在区域微细粒浸染型(卡林型)金矿床物源、成矿作用和构造控矿等方面研究的基础上,重点讨论了桂西北隆或金矿的地质地球化学特征。研究结果表明,该金矿店的穹隆构造、深断裂控矿、多层位赋矿和围岩蚀变等矿床地质特征,在滇黔桂三省区交界地区微细粒浸染型金矿中既具有普遍性,又表现出特殊性,其原生成矿硅质流体可能主要直接来自深部岩浆源分异作用,但由于是在地壳中成矿.不可避免地受到部分地层的物质和流体的混杂,因而属于地慢上隆-构造岩浆活化分异-深大断裂导矿-次级断裂、背科控矿-交代充填成矿的中偏低温热液金矿床。
Based on the study on the source, mineralization and tectonic ore control of the regional fine-grained gold (Carlin-type) gold deposits, the geological and geochemical characteristics of Beilong or gold deposits in western Guangxi are discussed. The results show that the geological characteristics of the deposit, such as dome structure, deep-rupture ore control, multi-layer ore-hosting and wall rock alteration, are not only common in the fine-grained diagenetic gold deposits at the junction of Yunnan, Guizhou and Guangxi provinces But also shows its particularity. The primary ore-forming silicic fluids may mainly come from the deep magmatic source differentiation directly, but due to the mineralization in the crust. Inevitably by some strata of material and fluid mixed, and thus belong to the slow Shanglong - tectonic magmatic activation differentiation - deep fault guide - secondary faults, back to the control of ore - account of filling mineralization in the low temperature Hydrothermal gold deposit.
