摘要
江西建昌大石沟金矿床的形成与火山作用有关的钱成侵入岩密切相关.根据金矿化所处的区域地质环境,对矿床地质特征及金的物质来源等特征的研究,认为该矿床属中低温浅成热液型金矿床.金矿床的成生与分布受控于沿北东-北北东向火山-岩浆带,金矿主要发育于陆相火山岩中.
The formation of Dashigou gold deposit in Jianchang, western Liaoning is closely related with pyroclasic hypabyssal intrusives. Based on the regional geological environment of the gold mineralization, and the study on the geological characteristics of the deposit and the source material of gold, it is believed that the gold deposit belongs to moderate -low temperature epithermal gold deposit. The formation and distribution of the gold deposit are controlled by NE-NNE volcanic -magma zone. Gold ore occurs mainly in continental volcanic rocks.
