纯橄榄岩

The composition range of Cr-sp in the two types of chromite deposit are distictly different.

两类矿床中副矿物铬尖晶石的成分从二辉橄榄岩至纯橄岩均显示出富Cr贫AL的演化趋势。

The analysis method about ultra-trace PGE in rock samples is successfully used in the study on the characteristic of PGE in Kudi ophiolite suite and the following conclusions are made:(1) The difference of the mantle normalization of PGE patterns between dunite, harzburgite and lherzolite in Kudi indicates that they are residual of multi-stage partial melt of the mantle.

将建立的岩石样品中超痕量PGE分析方法成功地应用于西昆仑库地蛇绿岩中铂族元素示踪研究，并得出了以下结论：(1)库地地幔纯橄岩、方辉橄榄岩和二辉橄榄岩之间铂族元素地幔标准化配分模式的差异，表明它们是地幔多阶段部分熔融的残余。

In meymechite dike and phogopite-plagioclase peridotite dike, MgO content respectively is 28.86%～ 32.78% and 27.28%～ 34.99%., they belong to the ferrguinous ultrabasic rock .

玻质纯橄岩脉和金云斜长橄榄岩脉，它们的MgO含量分别为28.86％～32.78％和27.28％～34.99％，属于铁质超基性岩。

The mantle shear zone formed at lithospheric extensional setting of Meso-Tethys and reworked by serpentinization, cataclasis, and compressional deformation including deformed lens such as ophiolite, gabbro, and chronite, thrust faults, and folds produced during closure of the Meso-Tethys.

在南北向挤压导致海盆消亡的早期阶段，处于深层侵位环境的地幔橄榄岩由于物性的不均一性，变形分解作用产生不同尺度的透镜网络，如蛇绿岩体、辉长岩脉、纯橄岩异离体、豆荚状铬铁矿体、眼球状橄榄石、辉石残斑晶等。
