羌塘及可可西里地区几个重要地质、构造与资源问题

Some aspects of the geology, tectonics and mineral resources in the Qiangtang-Hol Xil region, western China

笔者根据在羌塘及可可西里地区多年地质工作经验所获 ,结合该地区的其他地质资料 ,归纳总结出该地区具有重大地质意义的几大问题———羌塘盆地有无基底出露 ?玛尔果茶卡东山的片岩和辉橄岩 ,龙木错 -双湖板块结合带 ,南北向构造 ,新生代火山岩 ,羌塘盆地主体部分缺少早白垩世沉积 ,以及意义重大的接触关系 ;

The present paper deals, in detail, with western China the major aspects of the geology, tectonics and mineral resources in the Qiangtang-Hol Xil region, western China, including the presence or absence of the basement in the Qiangtang Basin, the discovery of schist and pyrolite in eastern Margog Caka, the Lungmuco-Shuanghu suture zone, NS-trending structures, ages of the Cenozoic volcanic rocks, the absence of the Early Cretaceous deposits in most parts of the basin and significant contact relations. Particular attention should be paid to the oil-gas and fresh-water resources in the basin and the collection of meteorological information in the future regional geological investigation.
