摘要
淋湘金矿床产于南秦岭古生界泥盆系地层中，容矿围岩主要为碳酸盐岩和粉砂质千枚岩、千枚岩，金矿体主要受近东西向断裂控制。主要载金矿物为黄铁矿、磁黄铁矿、黄铜矿、石英、褐铁矿，矿床的同位素特征和成矿物理化学条件表明：淋湘金矿的成矿物质来源于造山带围岩地层，属容矿岩石为沉积岩中的浅层渗滤同生热盐水型金矿床，成矿时代为燕山期。
The Linxiang gold ore deposit is found in the Palaeozoic Devonian strata. The gold orebodys occur in carbonate, fine-sandy phyllite and phyllite, and the major ore bodies are confined to the EW ore-control fault. Pyrite, limonite, pyrrhotite, chalcopyrite and quartz areall the major carrier minerals of gold. The stable isotope and ore-forming fluids characteristies suggest that the metallogenic substance comes mainly from orogenic belt strata, and thedeposit is a shallow-seated, medium-low temperature, leaching, syngentic gold depositwhich was formed in sedimentary in the Yanshan epoch.
