摘　　要：大庄子金矿1号脉矿床受大庄子断裂带控制,金矿体赋存在构造蚀变带内,矿体形态似厚层板状,沿走向呈脉状展布。矿石矿物具有多世代性,属中温热液充填交代蚀变岩型金矿床。经过对矿区地质、矿床地质和成矿阶段特征进行分析,并结合化探异常,总结出大庄子金矿床1号脉找矿标志,进而对深部探矿进行了初步预测。No.1 Vein of Dazhuangzi gold deposit is controlled by the Dazhuangzi fault zone.The quasi-lamellar, thick and tabular gold deposit occurs in the tectonic alteration zone, and spreads as vein along the strike.The min- erals in No.1 vein,which belongs to mesothermal and metasomatie deposit,is dominated by altered rock with mul- tiple generations.Based on the analysis of the characteristics of the geology of mining areas and the gold deposit, and the mineralization stages,the prospecting indicators of No.1 vein were listed,with reference to the geochemical anomalies.Then the preliminary deep prospecting was made.
