| 摘 要： | 广西天峨牛坪金矿位于右江盆地北东侧、天峨构造北端 ,以岩溶砂金为主 ,金矿体主要赋存于受多组断裂控制的溶蚀洼地及溶洞中。矿区内发现含 (金 )锑水晶的石英—方解石脉、方解石脉 ,脉体成份与砂金矿石成份相同 ,说明砂金矿源于岩金矿脉。此发现对黔桂地区在碳酸盐岩区寻找同类型金矿 ,对锑、水晶矿点 (床 )资料二次开发 ,研究该区金矿成矿作用 ,具有现实意义。

| Abstract: | Niuping placer gold deposit in Tian-e country of Guangxi is locaed at the Eastnorthern of Youjiang basin, the north of Tian-e structure, the ore bodies were occurrenced within karst depression and karst caves which were controlled by diversified string fractures. It is indicated that placer gold and antimonial (auriferous) quartz-calcite vein, calcite vein are the same origin, which are major of the metallic matter resources. This discovery has practical significance for looking for placer gold deposit in Guizhou and Guangxi carbonate region and secondary developing to stibnite and crystal ore bodies. |
