摘　　要：矿区内次火山活动对成矿起着重要的、直接的控制作用。次火山岩脉与成矿在空间上、时间上以及成因上的关系极其密切。在脉岩分布密集,脉体规模较大或局部隐蔽爆发作用形成的次火山岩——角砾岩构造等地段,对成矿最为有利。脉岩的产出部位,可以作为矿区及其外围找矿的重要标志。Subvolcanic activity is important to control mineralization directly. It is closely related with subvolcanic veins in space, time and genesis. It is favorable to the mineralization in the distribution area of dense subvolcanie veins of large scale or subvolcanic rock and breccia structures, formed by local concealed outbreak. The location of subvolcanic veins is the important indicator to prospecting and exploration in the mine and its adjacent area.
