Northwest Africa 6206 (NWA 6206)

Morocco

Purchased: 2008

Classification: HED achondrite (Howardite)

Petrography: Clastic polymict breccia. Clasts include those dominated by plagioclase (An85-93), zoned pyroxene (Wo5En64Fs31-Wo5En40Fs55), low-Ca pyroxene (Wo13En30Fs57) with augite lamellae (Wo32En28Fs40), ferroan olivine (Fa75-78), silica, ilmenite, chromite, Fe-Ni metal, and lithic fragments.

Classification: Classified as a howardite based on pyroxene and olivine FeO/MnO ratios (33 and 47, respectively), the diversity of clasts and their similarity to HED lithologies.

Specimens: A 3.03 g type specimen, including one thin section, is on deposit at UAb.
