Letter from Europe.
Gruss Gott from the Mineralientage Munchen - "the Munich Mineral Days" - where I have been chasing specimens, gossip, collectors, dealers and mineral history for 5 very solid days. I missed the Ste-Marie-aux-Mines show this year, so this was my first big show in ages and I had a lot to catch up on. Despite being on the go constantly, and fighting a heavy cold, I had a good time at the show and managed to get a few nice pieces for my own collection in between seeing a lot of superb but unaffordable (or worse still, affordable but just bought by somebody else) specimens. We were all helped by the beautiful weather, so there was plenty of opportunity to sit outside with a drink and chew the fat (and the ridiculously over-sized German sausages) with friends old and new. This atmosphere compensated a little for missing Ste-Marie, where relaxing sunlit conversation is taken for granted, the more so since past Munich shows have been known to take place in appallingly cold weather (speaking as an island dweller and beneficiary of the Gulf Stream, unused to continental winters).
I came to Munich early this year, but still not early enough of course. For instance I missed the best of a new batch of Indian cavansite, but the remainder was quite good enough thank you: deepest blue balls of crystals in rich specimens. Wilke Mineralien had a fine display of this and other recently acquired basalt quarry finery from India. However, as someone said, it was just more superb cavansite. The same was to some extent true throughout the show: more excellent galena from Bulgaria, more beautiful stibnite from Romania, more world-class scheelite from China, more Bunker Hill pyromorphite. Well, it's a common "lament" and I won't belabor the point. Except to say that do you remember when there was so much more Los Lamentos wulfenite that it was as uninspiring as today's glut of blood-red Moroccan vanadinite? Well, you don't see much anymore, and the prices of good pieces reflect this. Using this argument I bought yet another blood-red Moroccan vanadinite. Well, it is beautiful isn't it? It beads up my small display of the mineralogical spectrum through descloizite, crocoite, wulfenite (orange and yellow), brochantite (the stuff from Copiapo, Chile, selling as "aurichalcite" a few years ago), malachite, azurite, fluorite and erythrite.
So, what were the principal delights of Munich this year? Honors for quantity and quality must go to China, Romania, Bulgaria, India and Morocco; honors for one-off or two-off killers go to Sweet Home mine rhodochrosite, San Francisco mine wulfenite which stood out on a couple of stands, and to China again for things shown to me under tables.
Some of the Central European suites were very impressive. Galena from Madan, Bulgaria, was available in quantity and in some superb specimens. Geocommerce (Samena Gora 10, Plowdiv, Bulgaria 4003) had a particularly interesting display of small to large specimens featuring tabular spinel-law twins to 3 or 4 cm at reasonable prices (45 to 450 DM for most pieces). (Perhaps someone could explain to me why spinel twins are so common in galena in some localities, such as those in central Europe or South America, and so rare in others, such as Tri-State or Northern England?) Geocommerce's largest piece was a spectacular "museum specimen" some 30 cm square, covered in quartz and galena twins, the latter to about 5 cm. They also had some nice chalcopyrite and some globular rhodochrosite specimens. Other remarkable galenas - probably the best of their kind in the show - were also available from Pierre and Martine Clavel (4, Chemin vie Borgne, 38460 Cremieu, France). These show complex (untwinned) tabular rectangular crystals, with parallel overgrowths of small cubes, in perfect glittering condition, beautifully displayed on quartz matrix, or in parallel-growth masses of small, sharp cubes. The crystals reach several centimeters across and were priced at several hundred marks. Several excited collectors approached me with specimens from this lot, each saying they had acquired the best one. And they were all right. Very worthy specimens indeed.
Several stands had specimens of stibnite from Herja, Maramures, Romania. In this recently mined batch the lustrous black crystals vary from a centimeter to about 15 cm long, forming sprays and "hedgehogs" ("porcupines" might be more appropriate for the larger pieces) on and off matrix. The best have no damage and contrast well with the pale gray, rather vesicular quartz-rich matrix. Prices were generally very reasonable, although the best were priced accordingly high. A particularly attractive suite of specimens was available from Top Minerals (A-2700 Wr. Neustadt, Rudolf Hawel-Gasse 21, Austria), the owner of which - Rene Triebl - introduced me to an unusual dealer's expression: the "nail price." I'd heard of "keystone prices," "best" prices and so forth but never a nail price. It's the price you put on a specimen label if you like the specimen so much that you want it to grace your stand as long as possible: it's so high you might just as well have nailed the piece down. Also available from Herja were some fine specimens of semseyite in fans of small blades to 1 cm or so, the best again on a contrasting matrix of white quartz prisms; but the more typical pieces show the mineral - itself often tarnished black - on a dark sulfide matrix. Herja is also producing freibergite and fizelyite in reasonable specimens, some with a few rather dull bournonite crystals. These were mostly available from the smaller central European dealers dotted around Hall 5.
Some excellent sulfide minerals were also available from China. Chalcopyrite, galenobismuthite, galena, sphalerite and bournonite from "near Chenzou, Hunan" were seen at several stands. The chalcopyrite probably constituted the finest specimen material, and some excellent bisphenoids to 4 cm and complex (etched?) masses to 6 cm were being offered by Peter Bosse (Wilhelmhoher Alee 321, Kassel, Germany 34131). The latter are attractively associated with white lenticular calcite crystals on a reddish matrix. The bournonite (again Bosse had the best) forms bright, striated crystals, but specimens are small. Some of the sphalerite forms attractive blood-red crystals to 5 or 6 mm on matrix; other specimens show the more common black crystals but in sizes to 1.5 cm. According to Gabriel Risse, on the stand of Budil & Budil (Herzog Albrecht Strasse 36, Zomeding, Germany 85604), the mine is near the town of Yiou Guam Xiang, but I also saw a specimen of this characteristic chalcopyrite at another stand, labeled Leyang, Hunan. My knowledge of Chinese geography is not good enough to say whether these are all in the same area, or whether there is some disinformation at work again, as there has been with the scheelite/beryl combinations recently available. I talked to several people about this problem, but it is an intractable one, compounded by the transliteration of Chinese names into several European languages, using different transliteration regimes, and the fact that one rarely sees an actual mine name, so that the nearest town, village or city is given instead, with or without the addition of the word "mine." Thus, specimens of this sulfide suite may be seen labeled "Chenzou mine," although Chenzou is a good 200 km from the mine I'm told, and "Chenzhou" is the spelling on my maps of this south Hunan city near the border with Guangdong province.
A new Chinese mine, opened during the last year, is showing great potential for fluorite. This is the "Tao Ling mine, Yue Yang City, Hunan." (I feel fairly happy with this locality name because several people gave me exactly the same one, although I suppose this could mean merely that they all got their specimens from the same person. And a Yueyang city does exist in northwest Hunan on the Hubei province border!) This is a lead-zinc mine, but few sulfide specimens were to be seen at Munich. Several dealers had promising fluorite either as groups and singles of relatively small, delicately green, transparent cuboctahedra on matrix, as larger purple octahedra or as white drusy quartz pseudomorphs after the latter. The octahedra reach 4 cm on edge. Associations include transparent green sphalerite to 1 cm or so, tabular white barite, and small chalcopyrite crystals. Good specimens were available from Budil & Budil and from Christian Gobin, but both felt that the best was yet to come. Budil & Budil's stand also boasted a large lump of native bismuth showing the impressions of quartz crystal terminations. This was labeled from Yizhang, Hunan (also on my map in south Hunan on the Guangdong province border) and was purportedly an old piece. It is very similar to the better known and equally excellent material from Australia. Among other Chinese things I was told about, but didn't get to see, were stibiconite after stibnite and some bipyramidal vesuvianite - unfortunately I don't know any more than that (no sizes, or localities), but my informant was obviously impressed by them, and they might be worth asking your nearest China specialist about.
Excellent Chinese scheelite is still relatively plentiful. There seem to be two current sources, one yielding deep orange, sometimes gemmy, crystals with colorless beryl, and rarely with colorless fluorite or pink beryl, on mica. The other source produces gray, sharp, highly lustrous bipyramids to 3 cm on edge with arsenopyrite (very lustrous to 3 cm), quartz and cassiterite. The source of the orange scheelite has been in dispute for a while now; at first cited as from Hunan, it seems that Sichuan is now the more widely accepted province. I saw it labeled more precisely as both the "Leng Bao Dings Hill" or as "Ping Wu Town, Miang Yang City" - Mianyang city is northwest of the provincial capital Chengdu. Frederick Escaut (Ostrea Location, Route des Huitres, 17550 Dolus, France) still has the finest of this variety in crystals, to 8 cm or so on edge. Christian Gobin (Ourika, Chemin des Terres Longues, Venelles, France 13770) had the best of the gray crystals and said the material was from Jiao Kan Tchien, Hunan, a name remarkably like the Yiou Guam Xiang (given the change of language from German to French) cited as the source of the chalcopyrite mentioned above. I will not pretend to know which site is which here, and will hazard no suggestions as to whether geography or language decides the difference. Some wonderful cassiterite is coming from the same mine (or another close by) that produces the orange scheelite. It occurs as huge, complex twins to 10 cm and more across, some on matrix and some crowned with tabular colorless beryl several centimeters across. Other crystals are prismatic to lengths you would not believe. I saw only a limited number of these specimens and I look forward to seeing more; they set a new standard for the species.
In my last Munich report I also complained about problems with locality names, especially problems encountered with Russian sites. This resulted in a couple of interesting and informative letters from Russian mineralogist and mineralogical author Boris Kantor in Moscow. Explaining that he had had to devise standard Western spellings for Russian names himself for use in translated mineral articles, Boris listed several of his preferred versions: Nikolai mine (Dalnegorsk) should preferably be the Nikolayevsky mine; "Rudnui, Kusteni" should be Rudnyi, Kustanai; "Kerch, Keren Peninsula" should be Kerch Peninsula (and there is no "Kerch mine" as such, but a series of individually named open pits). He pointed out that "Oblast," as in "Kustenai Oblast," means "region" and that a "krai" (sometimes, wrongly, rendered "kraij") is a big oblast. He also says that the recently mined Russian crocoites currently on the market are probably from Beriozovsky (near Ekaterinburg), not Berezov (or Beriosova) which are different places, though all in the Urals. His last point was that the "galena after wire silver" recently pictured in the Mineralogical Record, and also from Beriozovsky, has been known for decades and is usually interpreted as a product of plastic deformation of galena squeezed through fissures by tectonic forces rather than as a pseudomorph. [Ed. note: Galena in an open cavity is not ductile! The pseudomorphic explanation is more credible.]
Back in Munich, and back with further locality confusion, lime-green olivine glowed on several stands. The locality was given as Sappat (or Sopat), Kohistan province, Pakistan. This is nice material. Crystals are generally rather rounded and etched, but are limpid and of very good color within. Individuals are all loose and generally show only one termination. An exceptional 3-cm doubly terminated crystal was held by Martin Rosser and Maria Grundner (Orthstrasse 14, 81245 Munchen, Germany). According to Martin the locality is at 13,000 feet and is a two-day walk or 9 hours on horseback from Dasso (between Gilgit and Islamabad). Either way you arrive with sore bits you didn't have when you started out. I was also told that the site had been attacked in force by specimen and gem miners and is likely to become rapidly depleted.
From the other side of the world (from where I'm sitting at the moment) there was little new to report. Australian opal was in evidence, especially in the show's colorful special exhibit of that mineral, but no new finds were represented. I was disappointed not to have been able to take up an offer of an escorted trip around this exhibit by an Australian dealer, as I'd have liked to learn more of the occurrences of this mineral. Among the many beautiful stones on view here I was most taken by one rather less colorful than most: a large opal "pineapple" pseudomorph after glauberite, from White Cliffs, New South Wales, surely one of the top ten pseudomorphs of all time. Otherwise the only antipodean item in quantity was crocoite from the Adelaide mine, Dundas, Tasmania, which was available on several specialist stands. Most of these pieces appear to have been etched from enclosing minerals and look it, being dull and milky. Nonetheless, they often show very large crystals for the species and can be very attractive if grouped in a sculptural arrangement of prisms. Specimens were reasonably priced and sold well.
From South America there was a lot of fine Argentinean rhodochrosite in evidence, another repeat performance, but at much more reasonable prices than heretofore. Superb, thick, polished slabs taken from intergrown or individual stalactites, some showing a fair degree of transparency, could be had for 50 to 500 DM. A special opportunity for European collectors was the chance to see fine specimens of the new mineral szenicsite at the stand of Aurora Minerals. Good specimens of this Chilean species were to be had from $400, and the best, featuring large (3 cm) crystals with powellite needles, for $12,000.
Russian minerals were popular, though quantities of many are still dwindling and prices still escalating. Dalnegorsk sulfides and fluorites are still available in fine specimens, and I bought yet another nice pyrrhotite (from MinGeo, Pardubicka 734, 500 02 Hradec Kralove, Czech Republic) unusual for its lines of minute octahedral galena crystals epitaxially arranged on the prominent, 8-cm pinacoid face. Top Minerals had a killer ilvaite from Dalnegorsk, a superb spray of large, lustrous black prisms sprouting from a matrix of quartz pyramids and spiky hedenbergite. This was regarded by several collectors as one of the best pieces in the show, and it was certainly one of the finest of all Russian ilvaites. It was sold before the show opened.
In Hall 5, certain canny Russian dealers, long steeped in the barter mentality and a regime of shortages, held court at tables brimming with unlabeled, unpriced specimens. It paid the collector to revisit these tables several times, as new batches of material were constantly being added. A four-deep throng of collectors was a periodic sign that something had been brought out. In this way scores of specimens of the honey-yellow blocky calcite from Sokolovskoye, Rudnyi, Kazakhstan, were moved on to collector's cabinets. A nice display of this material, which has been around in reasonable quantity for a year or so now, was also mounted by Wilke Mineralien. Russian and CIS rarities were dotted about the show in rather smaller quantities (I guess that's the way of it with rarities): from the Kola Peninsula Top Minerals had an unusual pale blue kovdorskite crystal from the type locality, Kovdor, and Fabre Minerals had an excellent plumbomicrolite octahedron, 3 cm on edge, from Mr. Ploskaya, Keivi. Jordi also had a good betekhtinite from Dzezkazghan, Kazakhstan, a rich mass of darkly iridescent, deeply striated crystals 1 to 2 cm long from the romantically titled Mine 55. As for other (generally smaller) rarities I turn once again for assistance to collector Simon Howell, whose dedication to obscure minerals far exceeds my own. Simon kindly provided me with the following eight paragraphs on some of the more interesting rarities available at Munich.
It's hard work being a systematic collector at the Munich show, where there is such a pronounced contrast between the small specks of material representing some fascinating chemical combination and the large and magnificent aesthetic specimens of more common species which appear to surround you at every moment. Nevertheless, the Munich show is well known for the excellent representation by dealers and collectors specializing in systematic minerals, and 1994 was certainly no exception!
Dr. Marek Kotrly (Severozapadni V/11, 141 00 Prague 4, Czech Republic) had a number of interesting species available from eastern European localities, including: tounkite and bystrite, from the type locality of Malaya Bystraya in Siberia; and several specimens of the rare copper-lead-bismuth sulfide-selenide soucekite, from Oldrichov, near Tachov, western Bohemia in Czechoslovakia. Specimens of another rare selenium mineral, poubaite (with clausthalite) were also available from the same locality.
As usual, Falko Baatz (Dorfstr. 21, Gerdshagen, Germany 18276) had a staggering array of systematic species available, the majority from their type localities, including belyankinite, betpakdalite, mushistonite, perlialite, rasvumite, shortite, shcherbakovite, srebrodolskite, strontiopyrochlore, tadzhikite-(Ce), vauquelinite, vitusite-(Ce), and yuksporite.
It was interesting to see some rare species available from Japanese localities at the stand of Hori Mineralogy (P.O. Box 50, Nerima, Tokyo 176, Japan), including specimens of minamiite and shigaite from their respective type localities of Okumanza Hot Spring, Gunma and the Ioi mine, Shiga, Honshu, and the hydrated manganese sulfate, jokokuite, from the type locality of Jokoku, Hiyama, Hokkaido.
One enormous specimen that caught my eye was a single crystal of sperrylite 2.2 cm (nearly an inch!) across, embedded in a sulfide matrix, from the well-known locality at Talnach, Siberia. This specimen had been placed directly below a large halogen spot light, and was almost dropped when I picked it up to examine the crystal because the sulfide matrix had reached such a high temperature!
Claudio and Marisa Albertini (via A Grandi, 22 Frax, Verta 28026 Omegna (Novara), Italy) had several specimens of the newly reported (1994) sodium antimonate brizziite, together with a large selection of both rare and more common alpine minerals from localities in Italy, which included good crystals of vigezzite. In addition, several specimens of aschamalmite (a lead-bismuth sulfide) were available from the first recorded occurrence in Italy, at Val Basso in the Valle Vigezzo, Novara.
A few small specimens of the rare palladium-tin mineral paolovite were offered from the type locality by Dr. Jarosmir Tvrdy (Vodarenska 10, 360 10 Karlovy Vary, Czech Republic), together with the platinum-antimony species, geversite, both from the Oktjabrs'koe deposit, Talnach, near Norilsk in northern Siberia, Russia; and Manfred Schaefer (Rosenstr. 5, Detmold, Germany 32756) had a wide selection of rare elements, sulfides and sulfosalts, including a large number of specimens of the rare iron-nickel-antimony-arsenic mineral, seinajokite, accompanied by native antimony, westerveldite and breithauptite, from the type locality at Seinajoki, Vaasa, Finland.
Helga and Horst Geuer (Am Sonnenhang 39, 53639 Konigswinter, Germany) had their usual excellent selection of specimens from Eifel and Lengenbach, the former including brenkite, calciobetafite, cuspidine, jacobsite, jasmundite, nickenichite, perrierite and srebrodolskite, and Lengenbach being represented by some early material from the Novacki Institute, which was also the source of some excellent specimens of marrite, rathite, seligmannite, trechmannite and imhofite, together with a small number of lengenbachite specimens of typical bladed form.
Back in the world of the more mundane species, there was also yet another new find of Spanish fluorite, this time from La Collada, Asturias, from a find known as the Geoda del Reguerin. These pale bluish crystals, which had made their debut at Ste-Marie-aux-Mines, reach 3-4 cm and were available in Munich in specimens up to a meter long at the stand of Fabre Minerals. Jordi is also the sole supplier of a new batch of pyrite, as sharp floater crystals and groups, the individuals to about 3 cm or so, from the Ambasaguas 1 mine, Ambasaguas, Logrono, Spain. Forms include both pyritohedrons (some rather elongated) and cube/pyritohedron combinations. These make excellent single-crystal pieces.
The institutional and private-collection displays at Munich presented the expected fine selection of goodies. Being a sucker for mineral collecting history, I was especially taken with that of London dealer Brian Lloyd (of Gregory, Bottley & Lloyd) featuring specimens sold at auction in 1829 by leading European dealer Henry (heulandite) Heuland. Alongside the auction catalog, marked with the names of famous buyers such as Henry Brooke, Countess Aylsford, Isaac Walker and Sir George Tuthill (whose fine collection was later to form the core of the more famous accumulation made by sculptor Francis Chantrey), were the actual specimens described in the lots! A nice historical snapshot. The Houston Museum displayed the usual suite of incredible specimens - phosphophyllite, cerussite on dioptase, etc.; it was nice to see them again, but as someone said to me: "Don't they have anything else?" The Royal Museum in Stockholm displayed their cobaltites (still the world's best as far as I know), including a plaster cast of the big dodecahedron with its customized carrying case. There were Alpine minerals in abundance too in the collector's cases, but not so many of them for sale around the show.
Munich is also a good show for books and magazines new and old. Standing out among the new ones worthy of mention was Meisterwerke sachsicher Minerale, a beautifully produced volume of 60 exquisite paintings of Saxon minerals by Eberhard Equit, originals of which made such a big impact in a special exhibit in the 1992 Munich show. Copies (which cost 179DM) are available from Equit Verlag (Fehrbellinerstr. 49, 10119 Berlin, Germany) and Christian Weise Verlag, publishers of leading German collector mineral magazine Lapis. And Falko Baatz had a copy of a relative rarity, a book on Russian gem minerals, Gemstones of Russia and Adjoining States, by J. P. Samsonov, published by the Agricultural Bank of Moscow in 1993. Fifty percent of the print run had been reserved by the bank for promotional purposes, but copies are available in the West for about 100DM. Also on Russian minerals, World of Stones magazine is still going strong and a further 2 issues were available at Munich.
By Sunday I was wiped out. Munich keeps me on my feet almost all day, and socializing late each night. It's a thoroughly enjoyable and generally good-humored event (collector jealousies aside!), and Munich itself is rumored to be a beautiful place, though I get to see little of it apart from the underground stations. Next year's show is later in the month: October 27-29, and the show theme will be "Fluorite, the collector's favorite." Should make for good special exhibits!

Bilbao and Barcelona Shows 1994
As is customary, the two largest mineral shows in Spain, Bilbao and Barcelona, were held in the fall. (It is surprising that Madrid, the capital of Spain, does not have a major mineral show.) As in other years, some new specimens could be seen, mainly from discoveries in Spain.
The Horcajo lead mine is a classical mineralogical locality in Spain (see the article about this locality in the Mineralogical Record, 25, 21-27). This year two interesting minerals surfaced from Horcajo. First, in the Bilbao show, Javier Garcia from Madrid had about two dozen cacoxenite specimens, some associated with heraunite, found on the dumps in the summer of 1994. The specimens are richly covered by rosettes and botryoidal crust of both minerals. From the same locality, Jordi Fabre had in the Barcelona Show about 20 pyromorphite specimens, the remains of more than 100, most sold at the Munich Show two weeks before. The specimens are very fine for the species and locality, and very reasonably priced. Two types of specimens are included: grass-green acicular crystals, and yellow, relatively blocky crystals. All specimens are crystal groups without matrix, and miniature size or smaller. Fabre stated that these specimens are from an old find, mined at least 30 years ago.
A large basalt quarry producing crushed stone for road construction is located between Albatera and Hondon de los Frailes, in Alicante province; it has been the source of some relatively modest epidote specimens in the past, with sheaf-like groups of millimeter-size crystals covering the surface. This year, Francisco Pinol from Alicante had specimens (from this quarry) with the epidote associated with titanite crystals or black garnet crystals, both up to 1 cm, and/or transparent quartz crystals up to 3 cm. Many specimens, obtained by dissolving the calcite to expose the enclosed epidote, are very nice.
Jose Javier Saura from Cartagena had in Bilbao and Barcelona newly mined barite from Teresita mine, La Union, Murcia. Specimens from this new find are groups of thin, tabular blue crystals up to 2 cm. These are found as floaters up to 15 cm. Larger specimens are very fragile and tend to get broken in the extraction process. In total, more than 1,000 specimens have been found. It is interesting to point out that this barite is found with blue color in the mine. Many "blue" barites from Asturias, also in Spain, are found colorless, but exposure to sunlight changes the color to a more or less intense blue. This process is natural in the dumps, but, of course, is also well known, and used, by many dealers.
Javier Saura also had blue barite from an unnamed mine near Gorguel, Murcia. The specimens from this locality are composed of crystals up to 5 cm, with their edges slightly rounded and faces slightly curved, probably due to some dissolution.
Among the specimens from localities outside of Spain, the most outstanding at the Bilbao Show was a malachite specimen from the Mashamba mine, Zaire, with curved leaves up to 5 cm. This specimen was sold by Luis Miguel Fernandez, a dealer from Zaragoza, to the Museo Mollfulleda, in Arenys de Mar, Barcelona. Martin Oliete, from Madrid, had in Bilbao five willemite specimens from Sterling Hill. These have relatively sharp, pink crystals up to 4 cm in a marble matrix. These, obtained about 15 years ago from Jim's Gems, Wayne, New Jersey, are probably the finest specimens of this mineral seen in Spain in many years.
At the Barcelona Show, Jordi Fabre had a fine old specimen of wurzite, a mineral rarely seen as good crystals. The small miniature specimen from Llallagua has two 1-cm hexagonal, very bright crystals in a matrix of siderite microcrystals pseudomorphous after some tabular mineral. The label is from the Harvard Mineralogical Museum.
Many interesting minerals of reference value for Spanish occurrences were to be found in Juan Vinals' booth in the Barcelona Show. This year, the most prominent mineral is planerite, found by Vinals near the prehistoric variscite and turquoise mines in Bruguers, Barcelona province. These mines, from the Neolitic age, are now classified as a site with historical interest, and collecting minerals inside is, of course, forbidden. However, specimens can be obtained at the surface in nearby areas. Planerite is found filling large fractures in quartz. Vinals had also two specimens of a Spanish classic: large (more than 10 cm) brannerite crystals from Sierra Albarrana. The specimens from Vinals are crude and somewhat damaged loose crystals, but of jumbo size for this mineral.
Also in the Barcelona show, Periz Minerales, from Granada, had some wulfenite specimens found in May 1994 in an old, small prospect, named Minillas del Hambre, near Quentar, Granada. The specimens, consisting of limestone matrix covered by yellow, tabular crystals up to 5 mm, are not very impressive by American standards, but are nice and rank among the finest found in Spain.
