摘要
在塔里木地台北缘断隆带上,广泛分布早元古代变质地层和同构造期蓝石英二长花岗岩.该区西部1140km^2范围内,已发现金及多金属水系沉积物综合异常20多处.其中大、小金沟金矿化区异常显示完整,具有典型性和代表性.根据该异常区原生金矿化地质特征、成矿控制条件、成矿作用与地质作用的关系,查证了本区曾经历了变质热液、岩浆热液和混合古地热水多期成矿作用的演化过程.
The early proterozoic metamorphic strata and syntectonic blue quartz monzonitic granite complex are widely distributed on the up faulted zone of the northern margin of Tarim platform. In the west of this region of 1140km.2,more than 20 synthetical anomalies of gold and polymetallie hydrographic net sedimaent have been determined. The anomalies of the Dajingou-Xiaojingou Auriferoustive. Based on the geological features of protogenous gold mineralization, metallogenesis and geological conditions, relationship between metallogenesis and geological function , a polyphase metalloyenesis has been proved.
