Writeup from MB 101:
Yamato 983730 (Y 983730) Antarctica Found: 1998 Classification: Ordinary chondrite (H4-5) Petrography: (A. Yamaguchi, N. Imae, M. Kimura, and H. Kojima, NIPR) A half of the PTS is type 4 ordinary chondrite which is in contact with type 5 lithology with a sharp boundary. The type 4 area shows a well-defined chondritic texture whereas in the type 5 area the chondrule outline is less clear and the matrix is recrystallized. Geochemistry: On the basis of the olivine and pyroxene compositions (Fa18-21, Fs15-20), both lithologies belong H group. Thus, this meteorite is a genomict breccia of type 4 and 5 ordinary chondrites. | ||||||||||||||||||||||||
