| 摘 要： | 结合近年来在青藏高原取得的区域地质调查成果,利用卫星图像遥感解译,对青海省杂多—囊谦地区进行了煤田地质遥感综合分析,建立了区域构造格架,分析了构造演化和成煤古地理环境,探讨了构造对聚煤作用和赋煤状态的控制与影响。结果表明:研究区煤层聚集和赋存与羌塘地体构造演化密切相关,构造演化经历了5个阶段,区域构造活动较强;煤聚集场所分布于拗陷边缘地带,局部形成富煤带;煤系除遭受复杂的错断、变形外,同时还遭受较强的剥蚀作用;华力西运动对本区煤系改造影响最为强烈;石炭纪聚煤中心地带位于解曲大型区域断裂带北岸,共圈定了早石炭世含煤远景区3处,晚石炭世含煤远景区6处。

| Abstract: | Combining geological investigation in Qinghai-Tibet Plateau,coal geology was analyzed by remote sensing interpretation in Zaduo-Nangqian Area of Qinghai Province,regional tectonic structure was built,tectonic evolvement and coal-forming paleo-geographical environment were analyzed,the control and influence of tectonics on coal accumulation and ocurrence were discussed.The results showed that coal accumulation and occurrence were related to tectonic evolvement of Qiangtang Block,tectonic evolvement experienc... |
