Chemical compositions of Antarctic meteorites I

Chemical compositions of Antarctic meteorites I
P(論文) Sixty-four chondrites (14H, 25L, 17LL and 8C), 32 achondrites and 2 rare stony-iron meteorites from Antarctica were analyzed by standard wet chemical analysis method. In the present paper the analyses of the chondrites and the stony-iron meteorites are reported. Many Antarctic meteorites are more or less weathered or oxidized.

Oxygen isotopic compositions of several Antarctic meteorites

Oxygen isotopic compositions of several Antarctic meteorites
P(論文) Oxygen isotopic compositions are reported for seven carbonaceous chondrites, seven ordinary chondrites, two enstatite chondrites, three lunar meteorites, and twelve achondrites. Three of the achondrites (ALH-77081,Y-74063,and Y-74025) do not belong to known groups; the first two of these are related to Acapulco.
