Actinolite and pyroxene phenocrysts separated respectively, from chlorite-actinolite schist and altered pillow basalt in the E'rou area of the eastern part of the Shuanghu-Longmuco suture zone, yield well-defined 40Ar/39Ar plateau ages of 235.9±2.6 Ma and 232.5±2.4 Ma. These nearly identical ages are interpreted as defining the age of the tectonothermal event of subduction-related collision along the Shuanghu-Longmuco suture zone.
在藏北龙木错－双湖缝合带东段双湖鄂柔地区，获得绿泥阳起石片岩中阳起石矿物的40Ar/39Ar坪年龄为(235.9±2.6)Ma和枕状玄武岩中蚀变辉石斑晶的40Ar/39Ar坪年龄为(232.5±2.4)Ma，两个年龄具有极好的一致性，记录了中三叠世晚期－晚三叠世早期沿龙木错－双湖缝合带发生俯冲碰撞作用的构造－热事件。

The crystallization temperature, pressure and depth of clinopyroxene phenocrysts from the picrite and basalt were calculated on the basis of the clinopyroxene-melt equilibrium principle.
根据单斜辉石-熔体平衡原理计算了苦橄岩中单斜辉石斑晶形成的温度和压力，其变化范围主要集中在1350～1387℃和16.6～21.3kPa，相应的深度为55～70km，大致代表了苦橄岩岩浆房的深度。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.
寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。

Among other things, paleovolcanic rocks at Shizuitang may be subdivided into olivine phenocryst-bearing basaltic komatiite and clinopyroxene phenocryst-bearing basaltic komatiite.
其中石咀塘古火山岩可进一步分为含橄榄石斑晶玄武质科马提岩和含单斜辉石斑晶玄武质科马提岩2种类型。
