【摘要】 通过大量野外地表构造地质调查,结合研究区已有地震剖面和其他深部物探资料,对西昆仑-帕米尔交接区域的前陆构造——依格子牙弧形推覆构造系统进行了详细的构造分析,发现了依格子牙表层薄皮弧形推覆构造系统及推覆系统下盘的依格子牙背斜——达尔鼻状构造,阐述了依格子牙弧形推覆构造系统与齐姆根主弧形构造的斜冲-走滑关系,提出了新生代西昆仑—帕米尔前陆依格子牙弧形推覆构造系统演化的成因模式.更多还原

【Abstract】 By amount of field geological and structural investigation and combined with the interpretations of seismic profiles and other geophysical data from the studied area, this paper analyze the structures of foreland belts, that is, the Yigeziya arc thrusting system in detail in the conjoined area between West Kunlun and Pamir, and discover the Yigeziya arc thin- skinned thrusting system in the shallow depth and Yigeziya anticline - Daer nose structures in the down wall of the Yigeziya thrusting system, and also show the oblique thrusting and strike - slip relationship between Yigeziya arc thrusting system and Qimugen main arc tectonics. The mechanic evolution models duing Cenozoic of Yigeziya arc thrusting system in the foreland of West Kunlun- Pamir are suggested.更多还原
