摘要
研究表明,洋鸡山金矿是与次火山作用有关的金矿床。主矿体直接产于火山通道中,近EW 向断裂(F1) 不仅是洋鸡山金矿的导矿构造,其边缘发育的次级羽状断裂又是金矿的储矿构造,并且对金矿床产出进行后期改造,使其产状复杂。
The Yangjishan gold deposit related to subvolcanic process is located within a volcanic conduit. The EW-trending faults are the passage ways for ore fluid, and the second-order fractures on their sides are the host structures. The cryptoexplosion crater and the second-order fractures are the ore-hunting indicators.
