【摘要】 据河西走廊西段敦煌—金塔一带区域地球物理场特征反映的构造格局,通过构造应力场和动力学分析研究认为,基于阿尔金走滑断裂带东北段存在尾端效应,产生一系列与走滑断裂伴随的裂陷盆地和挤压隆起,能量的消减和转换致使阿尔金断裂止于花海裂陷,向东并未延伸;在疏勒河两岸遥感影像和色调差异,主要反映两侧山前冲洪积扇发展不平衡,岩性含水性的差异,疏勒河隐伏断裂在地球物理场未能得到佐证;敦煌盆地地热田受NNE向张性断裂导热,NNE向压扭性断裂阻水阻热两重因素控制,热源除地壳正常增温还有壳内局部热源叠加。更多还原

【Abstract】 On the basis of comprehensive geophysical survey result in area of Donghuang-Jinta of west Hexi corridor recent years, it’s in this paper which was discussed about such 3 geological issues as extension of Altun fault, fault in Shule river, geothermal control and mechanism in Donghuang basin.更多还原
