四川省九龙县黑牛洞铜锌矿床为一个产于前震旦系江浪变质核杂岩中的富铜矿床,受穹隆内发育的环状滑脱构造系统控制。通过对矿床地质特征、成矿物质来源、氢氧同位素等方面的研究,认为矿床的成矿物质主要来自于深部,成矿热液是大气降水和变质水组成的混合流体。矿床的成矿时代为燕山期,矿床的形成与区域构造-岩浆热事件相对应。黑牛洞矿床为中高温变质热液矿床。
The Heinuodi copper-zinc deposit in Jiulong County, Sichuan Province, is a copper-rich ore deposit originating in the Jianglang metamorphic core complex of the former Sinian and controlled by a ring-like sliver detachment system developed in the dome. By studying the geological characteristics of ore deposits, the sources of metallogenic materials and the hydrogen and oxygen isotopes, it is considered that the ore-forming materials of the orebodies are mainly from the deep part, and the metallogenetic hydrothermal fluids are the mixed fluids composed of precipitation and metamorphic water. The mineralization age of the deposit is the Yanshanian period, and the formation of the deposit corresponds to the regional tectono-magmatic thermal event. The black hole deposit is a high-temperature metamorphic hydrothermal deposit.
