新疆克孜勒陶地区构造演化及控煤作用分析

Tectonic Evolution and Coal Controlling Effect in Kizilto Region, Xinjiang

利用遥感卫星图像解译,结合区域地质资料及野外实际调查资料,从构造演化的角度,对新疆克孜勒陶调查区地质构造形态和主要控煤构造的分布及性质进行了综合分析。结果显示:调查区含煤盆地类型为一断陷型内陆盆地,其煤层聚集和赋存与盆地基底构造、区域构造及后期构造活动等综合作用密切相关;控煤构造以褶皱断裂组合为主要特征,喜马拉雅期的构造变形对煤系改造最为剧烈;并圈定了同由路克、昔里必里、阿帕里克及库斯拉普含煤远景区。

Using remote sensing satellite image interpretation, combined with regional geological data and field investigation, from struc-tural evolution point of view, carried out comprehensive analysis of geological structural form and main coal controlling structures distri-bution in the Kizilto prospecting area, Xinjiang. The result has shown：coal-bearing basin in the area is a faulted depressed interior basin;its coal accumulation and hosting are closely related to integrated activities of basement structure, regional structure and succeeding tectonic activity etc. Coal controlling structures are mainly folds and faults, structural deformation during Himalayan stage violently reformed coal measures. Finally the paper delineated coal-bearing prospect areas of Tonyoluk, Xilbil, Apalik and Koslap.
