Writeup from MB 104:
Northwest Africa 10050 (NWA 10050) Morocco Purchased: 2014 Classification: Ordinary chondrite (L6, melt breccia) Petrography: In the light-colored, impact-melted portion contains olivine. Olivine exhibits weak mosaicism, but the plagioclase grains do not contain maskelynite. It is an impact melt with a glassy mesostasis. This portion contains several shock veins. In the dark-colored, chondritic portion contains olivine. Plagioclase grains are coarse and exceed 50 μm in size. Some grains are maskelynite. Geochemistry: In the light-colored, impact-melted portion: olivine Fa 24.1±0.2 (n=15), low-Ca pyroxene Fs20.8±0.4Wo1.4±0.2 (n=10), and Ca-pyroxene Fs7.0±0.3Wo45.8±0.5 (n=11). In the dark-colored, chondritic portion: olivine Fa 24.3±0.6 (n=12) and low-Ca pyroxene Fs20.4±0.2Wo1.6±0.2 (n=14). | ||||||||||||||||||||||||
