Petrography and mineralogy of the Grove Mountains (GRV) 021788 ureilite from Antarctica;

南极GRV021788橄辉无球粒陨石的岩石学和矿物学特征

The mineral-petrological characteristics and shocked effects of the monomict and polymict ureilites are studied in this paper.

本文主要综述单矿和复矿碎屑橄辉无球粒陨石的矿物-岩石学特征及冲击变质效应,并依据Δ17O,δ13C,mg#[MgO/(MgO+FeO)mol%],稀有气体,辉石丰度及辉石类型讨论橄辉无球粒陨石的分类和成因模式。
