浅析大石桥何家屯一带金矿地质特征及找矿潜力

Analysis on Geological Characteristics and Prospecting Potential of Hejiatun Gold Deposit in Dashiqiao Area

在大石桥何家屯一带目前已知有三家金矿,呈北东向展布,由北向南依次为金海、宝元及鸿腾金矿,含金石英脉矿体均沿构造蚀变带产出。成矿条件与其南东部的猫岭金矿相似,属于岩浆热液型矿床。通过对大石桥何家屯一带金矿地质特征的初步分析,表明该区仍有找矿潜力。

At present,there are three known gold deposits in Hejiatun area of Dashiqiao,which are distributed in NE direction,followed by Jinhai,Baoyuan and Hongteng gold deposits from north to south.The gold-bearing quartz vein ore bodies are all produced along the tectonic alteration zone.The metallogenic conditions are similar to Maoling gold deposit in the south and east of the deposit,which belongs to magmatic hydrothermal deposit.Based on the preliminary analysis of the geological characteristics of Hejiatun gold deposit in Dashiqiao area,the prospecting potential of this area is simple analysed.
