摘要：

火星陨石的发现使人类第一次获得了除地球之外，太阳系另一类地行星的岩石样品。目前已收集并确证的火星陨石共１０个，包括了４种岩石类型，其中有４个火星陨石是在南极地区发现和回收的。本文通过对火星陨石有关岩石学、矿物学、全岩化学组成、轻元素及稀有气体的同位素组成，以及同位素年代学特征的总结和对比，对火星幔的化学组成特征、岩浆作用及火星表面的化学风化作用等进行了初步的讨论。

Abstract:

Samples from another Earth like planet of the solar system is now available due to discovery of Martian meteorites.Up to 10 Martian meteorites covering 4 petrographic types have been found so far,including 4 meteorites collected in the Antarctic area. In this review paper,discovery on petrology,mineralogy,bulk chemical composition,isotopic compositions of light elements and noble gases,and chronology of the Martian meteorites are summarized. In addition,a preliminary discussion is concerned on chemical compositon of the Martian mantle,Martian magamatism and chemical weathering on the Martian surface,based on the study of Martian meteorites.
