Classification: Chondrite L3.5 S3/W2
Time/Place: January 2015
Mass: 900 gram

History: Purchased by Marcin Cimala in Zagora, January 2015.
Physical characteristics: Single stone with weathered exterior. A saw cuts shows many densely packed chondrules set in orange-brown matrix.
Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous porphyritic chondrules, most with mesostasis or glass. Scattered opaque matrix. Apparent mean chondrule diameter 714±303 µm, n=20.
Geochemistry: (C. Agee and N. Muttik, UNM) Chondrule olivine Fa22.1±10.4, Cr2O3=0.05±0.04 (wt%), n=30; chondrule low-Ca pyroxene Fs19.2±12.9Wo1.6±1.6, n=12.
Classification: Ordinary chondrite (L3), estimated subtype L3.5 based on mean value of Fa and 1-sigma standard deviation, and on the ferroan olivine mean value of Cr2O3 and 1-sigma standard deviation, similar to Chainpur L3.4 and Tieschitz L3.6 (Grossman and Brearley, 2005).
