Writeup from MB 103:

Northwest Africa 8385 (NWA 8385)

Morocco

Purchased: March 2014

Classification: Carbonaceous chondrite (CK5)

History: Purchased from a dealer in Morocco in 2014 by A. Jonikas

Physical characteristics: One weathered stone fragment with some remnant crust. Cut surface reveals brown matrix with sparse chondrules of various sizes and CAIs.

Petrography: (A. Rubin, UCLA) Microprobe examination of a polished mount shows the rock contains ~40 vol.% matrix material; magnetite modal abundance is about 10-15 vol.%. Chondrules average ~800 µm in diameter and are readily delineated, consistent with type 5. Plagioclase grains range in size from ~40-100 μm. The groundmass if relatively coarse, with an average grain size of ~70 μm.

Geochemistry: Olivine Fa32.0±0.8, n=13; high Ca-pyroxene Fs11.7±3.8Wo49.6±0.1, n=4.

Classification: Carbonaceous Chondrite (CK5) Chondrules are readily delineated, consistent with type 5.

Specimens: 20.85 g type specimen including a probe mount
