متن کاملAubrites: Their origin and relationship to enstatite chondrites
All ten known aubrites (enstatite achondrites) as well as Happy Canyon and Mt. Egerton, related anomalous meteorites, have been studied in order to understand their origin and relationship to enstatite chondrites. Mineralogically, aubrites contain 75-9B% enstatite (En98.76-99.54), 1-16% plagioclase (Anl.S-B.:), O.Z-K.l^r diopside (Wo40.1-46.1). 0.3-10.07f olivine (Fo99.79-99,99), <0.l3.7% metal...

15 صفحه اولSystematics and Evaluation of Meteorite Classification
Classification of meteorites is largely based on their mineralogical and petrographic characteristics and their whole-rock chemical and O-isotopic compositions. According to the currently used classification scheme, meteorites are divided into chondrites, primitive achondrites, and achondrites. There are 15 chondrite groups, including 8 carbonaceous (CI, CM, CO, CV, CK, CR, CH, CB), 3 ordinary ...
