Locality type:
Meteorite Class:
Meteoritical Society Class:
A 139 g piece of the type specimen shows a typical hexahedrite structure. Inclusions are common but small. Most are FeS, 1-3 mm in long dimension, and always surrounded by schreibersite. Oxidation is minor, and mainly at inclusion boundaries; there may be a heat-altered zone but better sample prep is needed to confirm this. There are parallel 1 mm thick bands crossing the specimen, which may be shear zones that were later annealed.
