内蒙古东乌旗查干楚鲁银铅锌多金属矿区地质特征及找矿标志

摘要

In the study of geological characteristics of the mining area, it is believed that the Chaganchulu Ag-Pb-Zn polymetallic deposit in Dongwuqi, inner Mongolia is late Yanshanian magmatic hydrothermal fluid and fracture-controlled sulfide polymetallic deposit. The late Paleozoic volcanic-sedimentary stratum is an important ore bearing country rock. And the close association of Yanshanian period potassium calcium-rich alkaline granite with metallic deposits in time and special distribution is an important prospecting indicator.%在研究了矿区地质特征的基础上,认为内蒙古东乌旗查干楚鲁银铅锌多金属矿是燕山晚期岩浆热液—断裂构造控制的硫化物多金属矿床.晚古生代的火山—沉积岩地层,是该矿区重要的赋矿围岩,而燕山期富钾钙碱性花岗岩在时空分布上与金属矿床关系密切是重要的找矿标志.
