江西省浮梁县猫儿颈金矿地质特征及找矿标志

Geological characteristics and prospecting criteria of Maoerjing gold deposit in Fuliang County,Jiangxi Province

猫儿颈金矿位于江南地台东段中部的鹅湖金矿化集中区。区内金矿体主要产于双桥山群漳前组中,在空间上受到韧性剪切石英脉带控制。矿区金矿体数量较多,但规模较小,在沿走向及倾向上均有尖灭再现,“豌豆荚”现象。矿床成因类型为中低温热液蚀变岩-石英脉型金矿床。文章通过分析矿区地质、矿体特征,总结矿区找矿标志,对鹅湖金矿化集中区剪切带型金矿勘查提供参考。

Maoerjing gold deposit is located in Ehu gold mineralization concentration area in the middle of the eastern part of Jiangnan platform.The gold deposits in this area mainly occur in Zhangqian Formation of Shuangqiaoshan Group,and are spatially controlled by ductile shear Shi Ying vein belt.There are a large number of gold bodies in the mining area,but the scale is small,and there is a phenomenon of"pea pods".The genetic type of the deposit is medium-low temperature hydrothermal altered rock-Shi Ying vein type gold deposit.By analyzing the geology and ore body characteristics of the mining area,this paper summarizes the prospecting criteria of the mining area,and provides reference for the exploration of shear zone type gold deposits in Ehu gold mineralization concentration area.
