摘要
在对龙门山的构造变形、沉积环境、地层古生物、石油地质、遥感地质、地球物理、同位素地质等专题研究基础上,综合归纳出龙门山造山带岩石圈演化的动力学模式——为多层次、乡阶段、深层破裂控制浅层变形的陆内俯冲模式。它不同于A型俯冲带模式,也不同于阿尔卑斯碰撞型造山模式,而是具有中国特色的C型(中国型)俯冲造山模式。
Depending on the studies of structural deformation, deposftional enviroments, stratigraphyand palaeontology, remote sensing geology, geophysics, petroleum geology and isotop geology, it ispointed out that the dynamical model of the lithospheric evolution in Logmenshan Orogenic Belt ismultilayered, multistaged and deep-fracture controlling shallow-deformation intracontinental subdu-ction medel, which is different not only from Ampferer-subduction model, but also from Alps-typedcollision orogenesis model, and which possesses the characteristics of Chinese-subduction model.
