(Northwest Africa)

Purchased: 2010 Dec

Classification: HED achondrite (Diogenite, polymict)

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia containing lithic clasts of several different olivine-bearing diogenites and sparse (<10 vol. %) basaltic eucrites with related mineral debris and altered metal. The primary metal has been extensively weathered to produce veinlets of iron hydroxides that crosscut the specimen and cause it to break apart in fragments.
