Writeup |
Writeup from MB 102:
Northwest Africa 7599 (NWA 7599) (Northwest Africa) Purchased: 2012 Classification: HED achondrite (Diogenite) History: Purchased by Stefan Ralew in 2012 from a dealer in Erfoud, Morocco. Petrography: (A. Irving and S. Kuehner, UWS) Composed of larger grains separated by regions of smaller crushed grains in a cataclastic or mortar texture. Predominantly orthopyroxene with accessory clinopyroxene, anorthite, large chromite grains, stained Ni-poor metal and troilite. Geochemistry: Orthopyroxene (Fs24.8-24.9Wo3.0-3.5, FeO/MnO = 30-34), clinopyroxene (Fs10.4Wo42.8, FeO/MnO = 22). Classification: Diogenite. Even though the examined thin section does not contain olivine, this material is virtually identical in terms of texture, pyroxene compositions and alteration to the NWA 7464 stones (and probably is paired with them). Specimens: 20.1 g of sample and one polished thin section are on deposit at UWB. The remaining material is held by Ralew. | ||||||||||||||||||||||||||||
