【摘要】 通过对天然地震剖面的解释,探索了南天山造山带、西昆仑(帕米尔)造山带和塔里木(塔吉克)地块的岩石圈大地构造关系,认为在研究区东西两侧,塔里木(塔吉克)地块为南北直接俯冲于西昆仑(帕米尔)造山带和南天山造山带之下的双向俯冲模式;在中部帕米尔地区,西昆仑造山带在帕米尔地区形成构造结并仰冲于南天山造山带的前陆冲断带之上。由此形成了两大新生代复活的巨型造山带,而造山带与塔里木(塔吉克)地块之间的俯冲和对接关系,展现了独特的"盆-山"耦合体系。更多还原

【Abstract】 After interpreting natural earthquakes,a exploratory research on the lithospheric tectonic relationship among South Tienshan orogen 、West Kunlun(Pamir)orogen and Tarim(Tajike)block has been done,and the author considered in west and east side,West Kunlun(Xindukushi)orogen and Tarim(Tajike)block subducts beneath the West Kunlun(Pamir)orogen and South Tienshan orogen in two directions;In middle Pamir area,a syntaxis has formed with the West Kunlun(Pamir)orogen obducts upon the South Tienshan orogen,and resulted in the two great orogens that rejuvenated during Cenozoic and the subduction and jointing relationship of two orogens and Tarim(Tajike)block,showing a specific "basin-and-range" coupling system.更多还原
