| 摘 要： | 阿哈大洼金多金属矿床位于青海省柴达木盆地北缘地区,该区地质环境复杂,成矿条件优越。目前已在该矿区发现金矿(化)体2条,银、铅、铜矿(化)体各1条。本次调查研究的重点是对区域成矿地质背景、矿区和矿床地质特征进行分析研究,进而探讨矿床成因。研究表明,北西—近东西向断裂构造控制着区内矿(化)体产状、形态及规模,加里东—印支期岩浆活动为本区成矿提供了热源与矿源物质。综合分析认为,阿哈大洼金多金属矿床为造山型金矿床。

| Abstract: | Ahadawa gold polymetallic deposit,located in North Qaidam Basin,Qinghai Province,has a complex geological environment as well as favorable metallogenic conditions.2 gold ore(mineralization) bodies have been found in the district and silver,lead and copper ore(mineralization) bodies,one for each.This paper studies geological background,deposit and ore characteristics and genesis of the deposit.It is shown that the NW-nearly EW fracture controls the occurrence,form and scale of ore(mineralization) bodies;Caledonian-indosinian magmatic activities provide the district with heat and ore sources.Comprehensive analysis thinks that Ahadawa gold polymetallic deposit is a orogenic gold deposit. |
