Writeup from MB 106:

Northwest Africa 11344 (NWA 11344)

(Northwest Africa)

Purchased: 2016 Oct

Classification: Ordinary chondrite (L3-4)

Petrography: (K. Metzler, IfP) Ordinary chondrite breccia, consisting of well-preserved chondrules of various textural types, set in a finer-grained matrix. The mean apparent chondrule size is 630 μm (240-1800 μm; n=49). Accessory phases are FeNi metal and troilite, mostly residing outside of chondrules. Olivine in the majority of components is equilibrated, but some components (chondrules, chondrule fragments) of petrologic type 3 are admixed.

Geochemistry: The mean olivine and low-Ca pyroxene compositions of the type 4 host are Fa25.3±0.4 (Fa25-26; n=11) and Fs18.6±4.1 (Fs9-22; n=12). The mean compositions in the type 3 fragments are Fa10.2±6.2 (Fa3-29; n=16) and Fs6.0±3.4 (Fs1-14; n=13).

Classification: L chondrite based on apparent chondrule size. Petrologic types based on the chemical variation of olivine and pyroxene.
