Writeup from MB 110:

Northwest Africa 5037 (NWA 5037)

(Northwest Africa)

Purchased: 2007

Classification: Carbonaceous chondrite (CM2)

History: The meteorite was purchased from a local meteorite dealer in Erfoud, Morocco.

Physical characteristics: Almost black rocks without fusion crust.

Petrography: Brecciated carbonaceous chondrite composed of small (apparent mean diameter about 300 µm) chondrules, chondrule pseudomorphs, mineral fragments, and some CAIs in abundant fine-grained ferroan matrix. Most chondrules and CAIs are surrounded by fine-grained dust rims. The matrix contains Fe-sulfides, pyrrhotite, and Ca-carbonates. Low analytical totals of matrix analyses suggest the presence of hydrous phyllosilicates.

Geochemistry: Matrix analyses yield FeO=32.1±1.3 wt% and an average total of 81.7±2.6 wt% (5 µm defocused beam, N=7), the latter indicating the presence of hydrous minerals.
