    摘要
  • 在新疆叶城县的西昆仑麻扎构造混杂岩带内,发育一套含煤砂砾岩地层,原陕西省地质调查院在1:25万区域地质调查中,将其划分为3个地层填图单元,即三叠系(T,未分)、三叠系赛力亚克达坂群(TS)和早—中侏罗世叶尔羌群(J1-2Y).这些碎屑岩主体是造山作用形成的山间磨拉石沉积,但各地层单元之间多为断层接触,顶底不全,岩石地层之间的新老关系和形成时代也不清楚.通过对该套碎屑岩的详细剖面测制和分析,依据其岩石组合特征、生物地层特征对比,将该套含煤砂砾岩重新厘定为早—中侏罗世叶尔羌群(J1-2Y),并自下而上再划分为:莎里塔什组(J1s^)、杨叶组(J2y)、塔尔尕组(J2t).它们主要是一套河湖相沉积的地层,是对西昆仑构造混杂岩带在早—中侏罗世隆起造山的沉积响应.
    In the Yecheng County, there exists a set of coal-bearing sandy conglomerate formation in the Mazha tectonic mélange of West Kunlun. Shaanxi Geological Investigation Institute divided this formation into three units in the 1:250000 regional geological survey, i.e. Triassic (T, non-layered), Triassic Sailiyakedaban Group (TS), and early-middle Jurassic Yarkant Group (J1-2Y). These clastic rocks were mainly intermountain molasses formed by orogenesis, but the contacts between all strata were faults. Except for the incomplete top and bottom, the sedimentary sequence and age of all strata were also without knowledge. By the measurement and analysis on the clastic rocks, and according to the rock assemblages and biostratigraphic characteristics, this set of coal-bearing sandy conglomerate can be redefined as early-middle Jurassic Yarkant Group which can be further divided into three units from the bottom to the top: the Shalitashi Formation (J1s^), Yangye Formation (J2y), and Targa Formation (J2t). They were fluviolacustrine strata and sedimentary response to the early-middle Jurassic orogenesis in the tectonic mélange belt of West Kunlun.
