Division and Space-Time Frame Foundation of Regional Stratum in the Western Sector of East Kunlun and the Altun Region

The western sector of east Kunlun and the Altun region are located in the binding site among the north-west,north-east and nearly east-west struct ures; and with the process of very complex geological structure,the mineralization is very favorable.Based on recently completed 1 :50000 regional geological and mineral survey results,through the analysis for regional tectonic and sedimentary construction,the division program of regional stratum and the establishment of space-time frame of stratum units have been propo sed in this paper,in order to provide new information for the study on geological background
