摘要
作者认为,银山铜多金属矿床的形成,起主导作用的不是韧性变形带。矿床深部有隐伏斑岩体存在。矿床的形成是多期次岩浆作用的结果。成矿作用与斑岩体侵入-火山喷发-潜火山岩再侵入一岩浆隐爆的整个成岩过程密切相关。矿床类型属火山。
The author believes that the leading role for the generation of the Yinshan deposit is not paid bythe tough deformable zone.A porphyrite intrusive body concealed is existed in the lower part of thedeposit,which was formed as a result of multiple magamtism.The metallogenesis is closely related tothe intrusion of the porphyrite body-volcanic eruption-the reintrusion of the cryptovolcanic rcck-thewhole diagenetic process of concealed magmatic eruption.The deposit studied belongs to a composite oneconsisting of the volcanic-subvolcanic-hydrcthermal type and the porphyry copper type.
