Study on Metallogenic Characteristics and Traget Areas in the Altyn Tagh Metallogenic Zone

Situated between the Tarim and Qaidam basins, the Altyn Tagh metallogenic belt stretches 600 km in NE-SW direction.The belt is mainly composed of Archean-Paleozoic metamorphic rocks and sed imentary rocks filling in the Mesozoic-Cenozoic fault-bound basins in the belt.The area has undergone multi-phased tectonic events including deformation, magmatism, tectonic up lift and strike-slip movement.Metallic, non-metallic and energy resource deposits have been developed in the belt and Au, Cu, Pb and Zn ore deposits have shown a great potential.The metallic deposits can be divided in to 9 types that are represented by Au deposits in the Caishigou, Dapinggou and Xiangyun areas, and Cu deposits in the Lapeiquan, Suolake and Kaladaw an areas.Based on the regional survey, geochemical and geophysical exploration, remote sensing and studies of mineralization and factors controlling the ore-forming as well as the use of GIS method, 5 metallogenic zones, 10 promising areas and 25 target areas have been determined in the belt.
