METEORITE TYPE & CLASS / OFFICIAL NAME or NUMBER (Meteoritical Bulletin Database): "NWA 13376" - Unequilibrated LL3.4 Chondrite
FALL/FIND LOCATION: Morocco, North West Africa
WEIGHT: 686 g
Northwest Africa 13376 (NWA 13376)
Classification: Ordinary chondrite (LL3)
Petrography: (C. Herd and H. Shek, UAb) Optical and microprobe examination of a polished thin section shows well-defined chondrules in a clastic matrix. Several large and numerous small iron oxide veinlets are present throughout, and metal has been strongly oxidized. Shock effects include weak mosaicism and planar fractures in olivine.
Geochemistry: (C. Herd and H. Shek, UAb) Data obtained by EMP examination of carbon-coated thin section: Olivine Fa23.0±10.9, Cr2O3 = 0.07±0.09 (n=62); Low-Ca Pyroxene Fs11.5±7.2Wo0.8±0.6 (n=69).
Classification: Ordinary chondrite, LL3. Estimated subtype 3.4. based on standard deviation of olivine and low-Ca pyroxene analyses, and presence of chondrule glass.
