orthopyroxene

Lithologic types of the massifs are mainly harzburgite and dunite, with subordinated lherzolite ( orthopyroxene: 5~ 7%). The textures and structures are similar to those of metamorphic rocks, and micro-plastic deformation of minerals is ubiquitous.

主要岩石类型是方辉橄榄岩和纯橄榄岩，二辉橄榄岩极少（单斜辉石含量5～7%），具有典型的变质岩结构构造特征，矿物显微塑性变形普遍发育。

The granulite facies retrograded stage with calcite+ dolomite+ diopside+ ilmenite+ phlogopite+ spinel ± orthopyroxene;

麻粒岩相退变质阶段，矿物组合主要为方解石+白云石+金云母+镁橄榄石+透辉石+钛铁矿+尖晶石±斜方辉石等；

They show layered intrusion features . The major rock-forming minerals include olivine, orthopyroxene, clinopyroxene, plagioclase and amphibole.

其主要造岩矿物为橄榄石 、 斜方辉石 、 单斜辉石 、 斜长石和角闪石.

Cumulate orthopyroxene occurs almost from top to bottom of the section.

堆积的斜方辉石几乎自下而上地分布在整个剖面中.

Orthopyroxene and olivine spinifex shows intermediate hollow skeletal crystal, most of which are replaced by talc, ankerite, chlorite and magnetite, but still keeps undamaged columnar pseudomorphism;

斜方辉石和橄榄石鬣刺呈中空骸晶状，大部被滑石、铁白云石、绿泥石、磁铁矿等取代，但仍保留完好的长柱状假像；
