广西南丹县同贡—塘先金锑矿床地质特征及找矿方向探讨

同贡—塘先金锑矿床位于大厂矿田外围。泥盆系下统塘丁组和益兰组是本区金锑矿脉的主要赋存层位。该区褶皱、断裂构造发育并有多条Au、Sb矿脉,地球化学异常反应强烈。同贡地质项目组综合分析成矿地质因素认为:应把找矿方向重点放在北部塘先区1号～3号矿脉、南部同贡区F3、F16断裂破碎带的深部探索上。

Probe into the Geologic Features and Ore Prospecting Directions of Tonggong-Tangxian Gold-antimony Deposit in Nandan County of Guangxi

Tonggong-Tangxian gold-antimony deposit is located on the periphery of Dachang Mine Field. The Lower Devonian’s Pond D Group and Ithran Group are the main occurrence layers of gold-antimony vein in this area in which the fold and fault structure had developed, there are several gold-antimony veins, and the geochemical abnormal reaction is strong. The comprehensive analysis on ore-forming geological factors made by Tonggong geological project team holds that the key points of ore prospecting directions should be put on the deep exploration of No.1～No.3 veins in northern Tangxian Area and F3 and F16 fracture zones in southern Tonggong Area.
