摘　　要：黑牛洞铜锌矿床位于四川省九龙县江浪变质核杂岩穹窿韧性剪切带内,为中型铜锌多金属矿床。通过对该矿床的地质特征、控矿构造特征及成矿物质来源进行研究,认为火山-沉积作用、韧性剪切塑性流变和脆韧性滑脱作用是黑牛洞矿床的重要控矿因素,矿体多分布在穹窿构造的转折端、早期韧性剪切带或与后期脆韧性滑脱带的叠加部位,火山-沉积作用提供了成矿物质来源,矿床的形成与区域构造-岩浆热事件相对应,黑牛洞矿床属中-高温变质热液矿床。The Heiniudong Cu-Zn deposit lies in ductile shear zones of the Jianglang metamorphic core complex dome. Research on geologic characteristic, ore-control factors, ore material source indicates that volcanic sedimentation was responsible for ore-formation, orebodies are controlled by shear plastic deformation and brittle ductile detachment, occurring in the hinge zone of the dome, the early ductile shear zone and the site of superimposition of the later brittle ductile detachment on the early ductile shear. The deposit is a moderate- to high-temperature metamorphic hydrothermal deposit.
