Writeup |
Writeup from MB 102:
Northwest Africa 8143 (NWA 8143) Morocco Purchased: July 2013 Classification: Ordinary chondrite (LL3) Petrography: (A. Rubin, UCLA) Chondrules are sharply defined, although they lack clear, transparent, colorless glassy mesostases. Much of the low-Ca pyroxene has polysynthetic twins and is thus low-Ca clinopyroxene. Olivine and low-Ca pyroxene are chemically heterogeneous. Chondrules have an average diameter of about 700 μm, indicating that the rock is LL and not H or L (which have much smaller chondrules). | ||||||||||||||||||||||||||||||
