卡拉库鲁木变质核杂岩是慕士塔格岩体的南缘部分,由长城系片麻岩以及燕山期花岗岩组成,其中长城系片麻岩为一套低角闪岩相的变质侵入岩,主要岩性为(石榴石)黑云二长片麻岩、(石榴石)黑云斜长片麻岩;根据变形程度,将其划分为内带、中带及外带,其中在内带见有燕山期花岗岩.剥离断层沿变质核杂岩边缘呈向南凸出的弧形展布.剥离断层上盘滑脱体由长城系赛图拉岩群高绿片岩一低角闪岩相的变质岩系构成.变质核杂岩构造的形成时代为早一中侏罗世.
The Karakulmu metamorphic core is the southern margin of the Muztag rock body and consists of the Great Wall gneiss and Yanshan granite, in which the Great Paleogene gneiss is a suite of metamorphic intrusive rocks of low amphibolite facies , Mainly lithology (garnet) biotite gneiss, (garnet) black plagioclase gneiss; according to the degree of deformation, it is divided into inner belt, middle belt and outer belt, of which the inner belt See the Yanshanian granite.The stripping fault along the edge of the metamorphic core complex was convex south curved distribution.The stripping fault detachment from the Great Wall of the Cela Rock Group high greenschist - a low amphibole facies metamorphism The formation of metamorphic core complexes is Early-Middle Jurassic.
