| 摘 要： | 对梧南金矿床成矿特征及成矿条件进行了分析和研究,发现该矿床的形成受构造、地层及岩性等因素的制约。容矿围岩为不纯碳酸盐岩,矿石矿物组分简单,围岩的热液蚀变发育,以硅化、黄铁矿化为主,金矿物粒径为0.001～0.032mm,主要载金矿物为黄铁矿。流体包裹体研究表明,成矿压力为(280～440)×105Pa,成矿深度0.93～1.46km,主成矿期的温度为120℃～340℃,与国内外卡林型金矿床具有相似特征,将梧南金矿划归为以不纯碳酸盐岩容矿的沉积、构造热液改造型金矿床。

| Abstract: | Research on the characteristics and conditions of ore-forming for Wunan Gold Deposit shows that it iscontrolled by geological structure, stratum and lithology. The ore body exists in impurity carbonate rock, and thecomponent of mineral assemblage is simple. The well-developed hydrothermally alteration is mainly identified bysilicification and pyritization, and the grain size of gold minerals is generally from 0.001 to 0.032 mm. Theauriferous minerals mainly comprise pyrite. Studies on fluid inclusion indicate that the temperature of oreformation is from 120℃ to 340℃ , the pressure is from 280× 105 to 440× 105 Pa, and the depth is from 0.93 kmto 1.46 km. Through comparing with other Carlin Type Deposits around the world from the aspects of geologicalcharacteristics, the ore genesis in the similarity is found. Genesis of the deposit is considered to be asedimentation-hydrothermal alterative type hosted in impure carbonates. |
