摘要: 东昆仑西段—阿尔金地区处于北西向、北东向和近东西向构造的结合部位,地质构造作用极为复杂,成矿作用十分有利。依据新近完成的1:5万区域地质矿产调查成果资料,通过区域构造与沉积建造的分析研究,提出该地区区域地层划分方案,厘定和建立了地层单位时空格架,为成矿带成矿地质背景研究提供新资料。

Abstract: 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-
