摘    要:东昆仑昆中断裂带乌妥一带分布20多个超镁铁质镁铁质岩残块(片),在野外地质调查的基础上,结合室内岩石学、岩石地球化学研究,属非典型的蛇绿岩残块(片),是东昆中断带在漫长的地质演化过程中残留在陆块边缘的洋壳物质,形成于洋中岛弧环境。分布于东昆中断裂带内及其附近,时代上属于早古生代。

关 键 词:地质特征  构造环境  乌妥超镁铁  镁铁质岩  东昆中断裂带

Abstract:More than twenty ultramafic mafic rock mass distributed in Wutuo area in Kunzhong fault belt of eastern Kunlun.Based on detailed field geological surveys,combining with laboratory petrographic tests and geochemical studies,it is regarded that these ultramafic mafic rocks are typical ophiolite rocks.These ultramafic mafic rocks are oceanic materials remained in the edge of continents during the period of the formation in middle Kunlun fault belt.They were probably formed in an arc island setting,and distributed in the middle and surrounding fault belts of eastern Kunlun,and the forming age is early Paleozoic.
Keywords:Geological characteristics  tectonic environment  Wutuo ultramafic mafic rocks  middle Kunlun fault belt
