Place/Time: 01.2015 in Morocco
Mass: 609g

Physical: Single stone with weathered exterior, saw cuts shows many densely packed chondrules set in reddish brown matrix.
Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous porphyritic chondrules, most with mesostasis or glass. Adundant opaque matrix. Apparent mean chondrule diameter 731±394 um, n=29.
Geochem: (C. Agee and N. Muttik, UNM) Ferroan chondrule olivine Fa26.3±13.6, Fe/Mn=71±37, Cr2O3=0.13±0.07 (wt%), n=30; chondrule low-Ca pyroxene Fs10.1±7.3Wo0.6±0.4, n=12.
Classification: Ordinary chondrite (L3.2), type 3.2 based on mean value of Cr2O3 in ferroan chondrule olivine and the 1-sigma standard deviation, similar to Kyrmka L3.2 (Grossman and Brearley, 2005).
