| 摘 要： | 细晶沟金矿床位于滩间山金矿田南东端滩间山南坡四五沟—细晶沟一带，具有一定找矿潜力。对矿区地、物、化、遥特征进行研究，可知矿区内的化探异常的分布、分带、元素套合特征，对金矿的指示意义很大。研究了矿床矿体与矿石特征，得到了矿体的倾向、倾角、矿体控制长度、厚度、控制的最大斜深以及细晶沟矿床的矿石类型。结合区域矿产特征，研究、分析认为，区内成矿与地层、构造、岩浆岩及热液蚀变作用4种控矿因素均较密切，高背景值的地层对金成矿的贡献、构造活动为成矿提供了导矿及储矿场所、频繁的岩浆活动为成矿带来了物质来源、热液蚀变为成矿提供了能源。

| Abstract: | The Xijinggou gold deposit is located in the Siwugou-Xijinggou area on the southern slope of the Tanjianshan at the south east end of the Tanjianshan gold ore field，and has certain prospecting potential.Research on geological，physical，chemical and remote characteristics of the mining area shows that the distribution，zoning and element combination characteristics of geochemical prospecting anomaly in the mining area are of great significance to gold mines.The characteristics of ore body and ore of deposit are studied，and the ore body′s tendency，inclination，ore body controlled length，thickness，controlled maximum slant depth，and ore type of the Xijinggou deposit are obtained.Based on regional mineral characteristics，research and analysis suggest that the four ore-controlling factors of mineralization and stratigraphy，structure，magmatic rock，and hydrothermal alteration in the region are all closely related.Mineralization provides ore-guiding and storage sites，frequent magmatic activities bring material sources for mineralization，and hydrothermal erosion provides energy for mineralization. |
