卡拉库鲁木变质核杂岩构造的特征及成因浅析

ANALYSIS OF THE STRUCTURE AND METAMORPHIC FACTORS OF KALAKULUMU METAMORPHIC CORE COMPLEX

位于新疆塔什库尔干县瓦恰地区的卡拉库鲁木变质核杂岩构造,由变质核杂岩、剥离断层及剥离断层上盘滑脱体三个部分组成;变质核杂岩由长城系片麻岩以及燕山期花岗岩组成,主要岩性为含石榴二长片麻岩、黑云斜长片麻岩、二长片麻岩;变质核杂岩构造的形成时代为早—中侏罗纪。

The Geological Structures of `KLKLM Metamorphic core complex in waqia,Tashi KuerKan of XinJiang are composed of Metamorphic core complex,peel thrust fawt and the sliding block in upper side of peel thrust.The metamorphic core complex consists of gnesis oluring Great Wall strata of Precambrian and granite Yan shan period of Gelogical History.Its composition includes:Garnetiferous monzonitiic-gneiss;Biotite plagioclase-gneiss;Monzonitic-gneiss.The Geological time of its Metamorphic genesis was during the lower and the middle Jurassic.
