Writeup from MB 100:
Northwest Africa 3195 (NWA 3195) Morocco Found: 2008 Classification: Ordinary chondrite (L, melt breccia) Petrography (A. Rubin, UCLA): Stone dominated by silicate melt composed of a mixture of chondrule fragments (100-600 μm) and mafic silicate crystals (6-20 μm) that precipitated from the melt. The mean olivine Fa content and relatively high standard deviation (Fa 14.5±5.5) reflect analysis of chondrule fragments and crystals formed in the chondritic melt. Also present are cellular metal-sulfide assemblages wherein metal cells are typically 10-50 μm in size and surrounded by troilite. An equilibrated clast (2 mm long) is present at the edge of one thin section. It is the mean olivine and pyroxene in the clast (Fa23.7±0.4; Fs19.5Wo1.0) that indicate that the rock is an L chondrite. The metal abundance in the clast is ~10 wt.%; this is within the L-chondrite range established by Keil (1962): 4.4-11.7 wt.%. The rock is classified as an L-chondrite impact melt breccia. | ||||||||||||||||||||||||
