| 摘 要： | 银山矿田的成矿岩浆建造，为一套典型的陆相中酸性次火山岩及与其紧密伴生的隐蔽爆破碎屑岩类．成矿主要发生在次火山作用晚期、岩浆隐蔽爆破之后的热液阶段，矿化与英安玢岩爆破岩筒紧密伴生．围绕爆破岩筒，蚀变和矿化具明显地分带性，次火山岩浆作用与成矿在物质组分上具一致性．

| Abstract: | The mineralizing magma formation of Yinshan ore field consists of a series of typical continental facies intermediate-acidic subvolcanic rocks and closely associated cryptoexplosion detrital rocks. Metallogenesis took place mainly in the hydrothermal stage after cryptoexplosion of magma, during late subvolcanism. Mineralization is closely associated with the explosive pipe of decite-porphyrite. Alteration and mineralization possess distinct zonation around the explosive pipe. The compositions of materials of subvolcanic magmatism and metallogenesis are same. |
