Abstract：Through 1:50 000 regional geological and mineral survey in the Altyn Tashdaban area of Xinjiang, the researchers summarized the progress and main achievements of the regional geological and mineral survey projects of J45E008021, J45E008022 and J45E008023. The Altun Group was divided into the first and the second formations of the Altun Group, and the Jinyanshan Formation was delineated into Jixian System of Middle Proterozoic, according to the characteristics of rock assemblage, metamorphic deformation, rock geochemical and isotopic chronology. The intrusive rocks were redivided into 4 periods and 6 mapping units, and the chronological frameworks of intrusive rocks were established. The lower limit of formation time of a regional ductile shear zone was determined as Middle Ordovician. 29 new mineral occurrences were discovered, 2 zinc ore bodies and 6 metallogenic prospect areas were delineated. This research would provide detailed basic geological data for the future exploration work in the study area.
