Three Antarctic iron meteorites, Yamato-790517,Y-791076 and Y-791694,were analyzed and Y-790517 was classified as a IIIA meteorite. Elemental distributions of Ge, Ga, P, S, Co and Ni in the six Antarctic iron meteorites, ALH-77263,ALH-77289,Y-790724 and the three meteorites listed above, were examined and mapped by a newly developed computer-aided microanalyzer (CMA) and presented in color printouts.
