Abstract

Two specimens of meteorites found last December in the Transantarctic Mountains may be the first carbonaceous chrondrites ever found under conditions of minimum terrestrial contamination.

Only 25 of the world's supply of some 2000 meteorites are carbonaceous chrondrites, representative of a celestial mix very much like that from which the planets must have been formed. Collected by a U.S.-Japanese team under National Science Foundation sponsorship, the meteorites arrived in the United States for study sealed in uncontaminated stainless steel lunar canisters locked in lunar transfer cases.
