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。

It mainly reaches the following achievements:1 Through the research of petrology and geochemistry, it is found that dunite takes over 85 percent in ultramafic intrusion, which largely contains Mg(39.66%-47.20%) and Fe(733%-11.17%). The containing of Mn. K. Na, P and Ti is less than 0.1 percent respectively. So it has typical characteristic of leaving of mantle rocks, while it doesnt have partly characteristic of melting.

主要取得以下认识： 1 通过对超镁铁质岩体的岩石学、地球化学研究发现，松树沟超镁铁质岩体主要由纯橄榄岩和方辉橄榄岩组成，纯橄榄岩占85%以上，变质浅，变形相对简单，富含Mg(39.66%—47.20%)和Fe(7.33%—11.17%)，Mn、K、Na、P和Ti的含量通常都低于0.1%，具有明显的地幔岩残留体性质，而不具有部分熔融的特征。

Trace element exhibits enrichment of LREE and antipathic elements. Trace element spidergram of obvious right deviation and extremely high containing of Sr, Zr and Hf are different from the negative anomaly of dunite which lies the bottom of ophiolite, but has weak positive anomaly.

微量元素显示LREE和不相容元素的富集，右倾的微量元素分布模式，异常高的Sr含量，Zr、Hf不同于蛇绿岩底部纯橄榄岩的负异常，而显示出微弱正异常，这些特征都与经典蛇绿岩层序底部的地幔橄榄岩不同。

There are two types of peridotites within this UHP belt.(1) Garnet peridotite consists of garnet lherzolite, garnet-bearing dunite, garnet-free dunite and garnet pyroxenite, which could be considered as one of the critical rock types in a continental-type subduction zone.

根据岩石学特征，我们确定柴北缘超高压带中发育有两种类型的橄榄岩：(1)石榴橄榄岩，岩石类型包括石榴二辉橄榄岩、石榴方辉橄榄岩、纯橄岩和石榴辉石岩，是大陆型俯冲带的标志性岩石。
