研究区位于青藏高原西北缘和中央造山带的最西段,地处塔里木陆块西南缘,是古亚洲构造域、秦祁昆构造域和特提斯构造域的结合部位,陆内消减、走滑作用强烈,大地构造位置特殊,是研究西昆仑地质演化的重要地区。俘虏沟地区花岗岩十分发育,主要分布于中生代三十里营房构造带,构造位置上属于甜水海微陆块北缘边缘裂陷带。形成时期主要为晚三叠纪、侏罗纪、燕山期。前人研究主要集中在塔什库尔干地区-库地一带,其它地区研究非常薄弱。
Located in the western part of the Qinghai-Tibet Plateau and the central western part of the central orogenic belt, the study area is located in the southwestern margin of the Tarim block. It is a combination of the ancient Asia tectonic domain, the Qin Qikun tectonic domain and the Tethyan tectonic domain. Strong, the tectonic position is special, is an important area for studying the geological evolution of the western Kunlun Mountains. The granites in the captivity ditch area are well developed and are mainly distributed in the Mesozoic Sishilili barrack tectonic belt and structurally belong to the marginal rift zone in the northern margin of the Tianshuihai micro-continental block. The formation period is mainly Late Triassic, Jurassic, Yanshan period. The previous studies mainly concentrated in the Taxkorgan area - Kudi area, the study in other areas is very weak.
