| 摘 要： | 隆林县隆或金矿属微粒型金矿，具有多层位、层状矿体为主、矿石和矿物成分简单、沉积结构构造特征，属典型层控矿床。矿床成因与生物礁的消失、滑塌事件、深水火山碎屑硅泥质上超盆地的叠覆、以及有机质的热解和分异有关。火山作用提供金的来源，火山～碎屑～浊积岩相为矿源层和含矿层，并受沉积盆地的关闭和开启影响，形成成岩矿床、成岩～后生或后生矿床

| Abstract: | The gold deposit at Longhuo in Guangxi belongs to micro-grained type gold deposit. The gold orebodies occur as bed in poly-horizons. The compositions of gold ore and minerals are simple and the ore is of sedimentary texture and structure. So the deposit is a typical strata-bound ore deposit. Its genesis is associated with the disappearance of biological reef, slump events, the superposition of deep-water pyroclastic siliceous and argillaceous basins, the thermal dissolution and differentiation of organic materials. The gold comes from volcanism. The source beds and ore-bearing beds are volcanic-clastic-turbidite lithofacies, and are influenced by the close and open of sedimentary basin to form diagenetic, diagenetic-epigenetic, or epigenetic ore deposit. |
