| 摘 要： | 综合利用地震剖面解释和地面地质资料分析,较为准确地揭示了位于西昆仑帕米尔逆掩推覆带的结构和变形特征.研究表明,帕米尔逆掩推覆带是帕米尔与南天山对冲碰撞带,呈东西走向,区内发育三、四排逆冲断层,且逆冲断层出露地表,反映出帕米尔向北逆冲推覆的特征.帕米尔逆掩推覆带由南向北的冲断作用表现为浅层滑脱的薄皮冲断为主,各次级断片成叠瓦状构造样式,其断片南倾的格局是由于来自南天山冲断系统深部双重冲断构造的背景下实现.

| Abstract: | Based on various date such as 2D seismic profile and field geologic survey,the structural and deformation al features more accurately of fold-thrust belt in the Pamir,West Kunlun was disclosed.The study indicates that the Pamir overthrust nappe structure is the ramp collision belt of Pamir and Southern Tienshan fold-thrust belt,and shows east-west direction,the belt can be divided into several rows of surface thrust faults,the thrust faults exposed surface,reflecting the Pamir thrust northward features.Thin... |
