. . . and the oldest piece of earth

Scientists at the Western Australian Institute of Technology in Perth have discovered the oldest fragments of the earth's crust, according to the August issue of Australia's SCIENCE AND ENERGY NEWSLETTER. Bob Pidgeon and Simon Wilde found the 4.3-billion-year-old zircon crystals in the Jack Hills area, about 700 kilometers northeast of Perth. The crystals are about 200 million years older than other zircon crystals found previously in Australia and are thought to be 250 million years younger than earth and the solar system.
