Writeup from MB 110:
Northwest Africa 14319 (NWA 14319) Morocco Purchased: 2021 August Classification: Carbonaceous chondrite (CM2) History: The meteorite was purchased from a dealer in Morocco. Physical characteristics: Many small dark grayish to black and brown individuals mainly without fusion crust. Petrography: Carbonaceous chondrite composed of small (apparent mean diameter about 300 µm) chondrules, chondrule pseudomorphs, mineral fragments, and rare CAIs many of which surrounded by fine-grained dust rims set into abundant fine-grained matrix. Matrix is Fe-rich with abundant Fe-sulfides and rare Ca-carbonates. Low analytical totals of matrix analyses suggest the presence of hydrous phyllosilicates. No apparent lithologies with different petrologic type on thin section scale. Geochemistry: The olivines and low Ca-pyroxenes are highly variable in composition with Fa0.4-38.4 (mean Fa4.1±7.5; n = 31) and Fs0.7-4.6 (mean Fs1.6±0.8; n = 30). Oxygen isotopic composition (A. Pack, UGött): δ17O = -1.437, δ18O = 3.504 (all permil). Classification: Carbonaceous chondrite (CM2) | ||||||||||||||||||||||||||||||||
