According to the geochemical data, the formation of mantle peridotite might be: during the spreading of ocean floor, the MOR mantle underwent variable degrees of partial melting and formed the depleted mantle peridotite with podiform chromitite; during the spreading of ocean basin, intra-ocean subduction happened, REE and LILE rich fluids containing water derived from the subduction slab migrated upwards and metasomatism happened to peridotite relic.

康金拉矿区的地幔橄榄岩的地球化学特征反映了其形成过程的复杂性，表现为：洋底扩张期间，扩张脊下的MOR型地幔的经历了不同程度的部分熔融，形成了亏损地幔橄榄岩，该地幔橄榄岩中赋存了来自深部的豆荚状铬铁矿。

Well-documented Lu-Hf isotope data from the oceanic basalts show that,the starting area of magma melting for the MORBs derived from the DMM component would be in the the depth of garnet peridotite,i.e.at the depth of 80―90 km instead of less than 60 km,which is at the depth of spinel peridotite as proposed early.The HIMU component,which is characterized by its high rediogenic lead,is refered as a special mantle component differentiated at some time in geological history from the lower mantle.A correlation study of Hf-Nd isotope between the chondrite and oceanic basalts implies that no isolated primitive mantle might have remained.

大量的大洋玄武岩Lu-Hf同位素研究表明：具亏损地幔端元来源的洋中脊玄武岩岩浆部分熔融的初熔区位于石榴石稳定场深度，即深度为80-90 km的石榴石二辉橄榄岩地幔，而不是原来所认为的尖晶石二辉橄榄岩区(深度小于60 km)；以高放射成因Pb为特征的高U地幔端元应代表了下地幔物质在某一特定时期发生分异作用的结果；球粒陨石与大洋玄武岩Hf同位素对比研究表明，没有原始地幔物质能保留至今的迹象。

In this paper ophiolites in the Western Zhungeer are divided into two types: One of them is assemblage of metamorphic peridotite troctolite gabbro; another is that of metamorphic peridotite pyroxenite gabbro.

本文将西准噶尔地区蛇绿岩分为两类：一类是变质橄榄岩橄长岩辉长岩岩石组合；另一类则是变质橄榄岩辉石岩辉长岩岩石组合。
