摘要: 王家湾金矿床位于江南造山带浏阳–醴陵地区，矿体主要赋存于新元古界冷家溪群雷神庙组中，矿石类型主要为石英脉型和蚀变岩型。矿石中金属矿物主要有黄铁矿、毒砂，非金属矿物主要有石英、白云石，矿石的结构主要有碎裂结构、填隙结构和交代结构，矿石构造主要有脉状构造和浸染状构造。围岩蚀变类型主要有硅化、黄铁矿化和碳酸盐化。矿体受层间裂隙、岩性接触界面等控制，金的富集与黄铁矿、毒砂等金属硫化物密切相关。
Abstract: The Wangjiawan gold deposit is located in the Liuyang-Lilin area of Jiangnan Orogen. Orebodies primarily occur as veinlet and disseminated ores that are mainly hosted in the Leishenmiao For-ma-tion of Lengjiaxi Group. The ore minerals are mainly pyrite and arsenopyrite, the gangue minerals mainly include quartz and dolomite. The major ore textures include cataclastic, interstitial and replacement textures. The major ore structures include veins, and dissemination structures. The alteration styles include silicification, pyritization and carbonatization. The Orebodies are controlled by interlayer fractures and lithologic contact interface, gold enrichment is closely related to sulfides such as pyrite and arsenopyrite.
