Since olivine is silica-unsaturated, quartz and olivine never coexist in the same rock. Therefore, in mantle peridotite and other ultramafic rocks, primary quartz can never be found.

由于石英和非饱和SiO_2的橄榄石不能共生，因此在地幔橄榄岩和超镁铁岩中不存在原生石英。

This paper gives a brief review of the characteristics and petrogenesis of mantle peridotite in continental subduction and collision belts, and then discusses in more detail the petrogenesis of peridotites in the North Qaidam ultrahigh pressure metamorphic belt.

论述了大陆俯冲碰撞带中地幔橄榄岩的基本特征和成岩类型，并重点讨论柴北缘超高压变质带中不同性质的橄榄岩及其成因。

The research results imply that the regional tectonic stress field has resulted in deformation and flow of upper mantle material with clockwise rotation,and make the alignment of upper mantle peridotite lattice parallel to the direction of material deformation. The deformation of the crust and upper mantle is possibly vertically coherent deformation.

研究表明青藏高原东北缘上地幔物质在区域构造应力场的作用下，发生了顺时针旋转的形变以至流动，使得上地幔中橄榄岩的晶格排列方向平行于物质形变或流动方向，上地幔变形和上覆地壳变形可能存在垂直连贯变形特征。

In respect of mineralogy and petrology as well as strontium isotope, the Pl-lherzolite exhibits some features of transition from the cumulates to the mantle peridotite.

在矿物成分、化学成分及锶同位素等力面，含长二辉橄榄岩具有介于地幔橄榄岩和堆晶岩之间的某些过渡特征。

Through analysis of the experimental data about ultrapotassic rocks, typeI ultrapotassic rocks came from the source region of phlogopite harzburgite that had undergone metasomatism of fluid enriched in silica and potassium; while the source region of typeⅢ potassicultrapotassic volcanics is carbonated peridotite mantle bearing potassic amphibole.

综合超钾质岩石的实验资料，可知区内I型超钾质岩的源区以富硅、富钾流体交代形成的金云母方辉橄榄岩为主；Ⅲ型钾质超钾质岩浆源区则以斜辉橄榄岩地幔为主。

The distributed of gold in the different zoning of xenoliths are inhomogeneous; from peridotite to pyroxenite, gold content incresed; in the transition belt of iherzolite,the sample emerged high positive anomaly; the content of gold in zoning clear is lesser.

金在包体不同带中的分布是不均一的；随橄榄岩向辉石岩的过渡，金的含量增高：在二辉橄榄岩过渡带的样品中常出现较高的正异常；分带模糊的样品中金含量高于分带清楚的样品。

According to layered rock-sequence and types, the body is divided into two zones; the upper gabbroites and the lower zone composed of pyroxenite, peridotite and coarse altered gabbroite.

杂岩体按岩石类型分为由辉长岩类组成的上部带和由辉石-橄榄岩组成的下部岩带构成。
