Diamonds found in Antarctic meteorite



Tiny crystals of diamond have recently been found in a 10A-kg iron meteorite collected from the Allan Hills region of the Antarctic ice cap in 1977. The discovery was reported in Nature by Roy S. Clarke, Jr., Daniel E. Appleman, and Daphne E. Ross, all of the Smithsonian Institution's National Museum of Natural History. (The Antarctic Meteorite Program is a joint activity of the National Science Foundation, the Smithsonian Institution, and NASA. The specimens are preserved, described and distributed by NASA's Planetary Materials Laboratory at Johnson Space Center, Houston.)
