    Abstract:

    Information based on extensive investigation of mineral resources in recent years, the Tibet autonomous region and the Tibet autonomous regional mineral resources potential evaluation research on the system, detailed mineral resources information, the system summary writing Tibet metal metallogenic series of ore deposits and metallogenic spectrum (four papers). This paper discusses the Karakoram (qiangtang) -jinshanjiang metallogenic provinces (including Xijingulam-jinshajiang metallogenic belt, North qiangtang-changdu metallogenic belt and the Karakoram-tanietaweng metallogenic belt) of mineral geological characteristics and distribution regularity of mineralization and metallogenic series. Qiangtang- jiangshajiang metallogenic province in addition to the Karakoram -tanietaweng metallogenic belt (Ⅲ - 37) DuolonCu, MeiduoSb and DanquFe deposits when the song deposit distribution in southern Qiangtang and Tanietaweng region, other major ore deposits are distributed in Cangdu jinshanjiang area. Qiang south region are mainly related to middle-late yanshan movement in the magmatism, such as more DuolonCu deposit metallogenic series, related to Cenozoic fluid - transformation, such as MeiduoSb deposit metallogenic series and related to yanshan period stratabound hydrothermal - transformation, such as DanquFe deposits when the song deposit metallogenic series. Himalayan period in Cangdu-jinshajiang region mineralization is one of the most important metal deposit metallogenic events. Orogenic belt have large-scale strike-slip stretching, nappe shear and its associated rich potassium alkaline porphyry (magmatic hydrothermal), arc first on both sides of the foreland basin formed nappe basin fluid system (characterized by hydrothermal convection system), constitutes the YulongCu deposit represented by CuMoAg metallogenic series and the NormaPb deposit represented PbZnSb metallogenic series of ore deposits, and MeiduoSb deposit as representative's SbAg metallogenic series of ore deposits.
