| 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。成矿作用表现出多期次、多成因的特点,与江浪变质核杂岩的形成与演化有着密切的联系。本文通过对地质特征、构造样式解析及成矿物质来源研究,华力西期的伸展性顺层韧性剪切作用和燕山期脆韧性重力滑脱的叠加是黑牛洞形成富矿的根本原因。通过对黑牛洞铜锌矿床的地质特征、控矿构造等构造成矿作用分析,探讨了黑牛洞铅锌铜矿床的成矿规律,为下一步深部及外围找矿提供理论依据。

| Abstract: | The Heiniudong Cu deposit is a medium-sized Cu-Zn polymetallic deposit lying in the ductile shear zone of the Jianglang metamorphic core complex dome.The ore-formation is in close relationship with the formation and evolution of the Jianglang metamorphic core complex and characterized by multi-stage and multi-genesis.The study of geological features,structural style resolution and ore material source indicates that the Hercynian extensional bedding ductile shearing and superposition of the Yanshanian brittle-ductile gravitational slippage were responsible for the formation of ore shoot.This paper makes an approach to metallogeny of the Heiniudong Cu-Zn deposit based on geological features and ore control structures. |
