摘要
分析了中国新疆维吾尔自治区境内沉积盖层中的不整合及不同时代形变的区域性分布特征,并评价了喜马拉雅造山运动对新疆现今构造的影响。指出,塔里木盆地(地台)在晚第三纪和喜马拉雅运动期就成为新疆主要的油气生成区。塔里木盆地仅受到了谐振运动的影响,这种谐振运动与四周活动区的构造活动有关(使塔里木克拉通盖层的同沉积构造及岩相带复杂化),但这种谐振运动在靠近褶皱带的范围内也未能形成褶皱山。只是新生代晚期的形变作用才形成了塔里木地台的现今推覆褶皱框架,塔里木地台的盖层是一个潜在的含油气领域。
The authors analyzed the characteristics of regional unconformity distributions in sedimentarycover and their deformation in different geological periods within the boundaries of Xinjiang Uygur Autonomous Region of China, and evaluated the effect of Himalayan orogeny on structures existed in Xinjiang.The result showed that Tarim basin (Platform) became a major area of hydrocarbon generation in Neogeneand stage of Himalayan movement, and only underwent the effect of resonance movement that was relatedto the structural activities in the surrounding active areas (thus making the syndepositional structures andlithofacies zones in Tarim cratonic cover complicated). However, folded mountains were not formed in areasnear folded belt under the resonance movement. It was deformation in lute Cenozoic that formed existingnappe fold framework on Tarim platform. Tarim's sedimentary cover is believed to be a POtential Petroleumbearing domain.
