| 摘 要： | 研究藏东缘大型复合盆地喜山期陆内造山与成矿作用的目的,在于建立横断山型陆内碰撞造山构造模式、成岩成矿模式。根据地层接触关系、构造变形特征、矿床分布规律的研究,证实盖层褶皱推覆运动发生在早喜马拉雅期;盆地内的推覆(滑覆)构造圈闭、走滑断裂构造圈闭、走滑推覆脆-韧性剪切带圈闭、与造山带走向近直交的横向构造圈闭是主要的成岩、成矿空间。通过横断山型陆内造山动力学和喜山期成矿作用研究,分别建立了“横断山型”陆内碰撞造山模式和藏东缘大型复合盆地的成岩成矿模式。 |

| Abstract: | The study destination of intracontinent orogen and metallogenesis in Himalayan epoch of the large composite basin, East Tibet is to establish the tectonic model and the diagenesis-metallogenesis model on Hengduanshan type Intracontinent collision orogen. It is proved that the cover folding nappe would be in the early Himalayan epoch by the research of the stratum contact relation, the tectonic deforming characteristic and the ore control factor. The main diagenism, metallogenic spaces are the trap of the nappe structure, of the strike-slip structure, of the strike-slip nappe brittle-ductile shear belt and of the cross structure orthogonal with the strike of the orogenic belt. According to the study of the intracontinent orogen dynamics and metallogenesis in Himalayan epoch, this paper has established the tectonic model of Hengduanshan type intracontinent orogen and the diagenism-metallogenesis model of the large composite basin in eastern Tibet. There is the fact that the metallogenesis of the porphyry copper deposit was in the tectonic change period from the peak of the early Himalayan movement to the mid-Himalayan movement. And, the Pb-Zn (Ag ) mineralization in the hrust nappe trap was resulted from the late Himalayan movement. |
