摘要:
金厂峪金矿床作为冀东矿集区规模最大、开采历史最悠久的矿床之一,为中国的金资源量提供了保障。目前，该矿床找矿工作遇到瓶颈，为解决深边部增储的关键问题，根据“三位一体”勘查区找矿预测理论与方法对其进行了立典式研究，建立矿床“三位一体”成矿预测模型对深边部找矿工作进行指导。通过对金厂峪金矿床的典型剖面、巷道进行大比例尺构造、矿化蚀变填图，查明了成矿构造和成矿结构面，刻画了矿区成矿构造空间展布形态。在确定金厂峪金矿床成矿地质体基础上，进一步梳理其与成矿构造和成矿结构面、成矿作用特征标志间的关系，初步构建了“三位一体”成矿预测模型，推测深部找矿目标应集中在Ⅴ号矿脉0勘探线—55勘探线-1 000~-600 m标高，外围找矿靶区则应在Ⅰ号、Ⅲ号、Ⅳ号矿脉的西侧。经工程初步验证，“三位一体”成矿预测模型预测效果良好，对金厂峪金矿床的接续性找矿生产工作具有良好的现实指导意义。

Abstract:
Jinchangyu Gold Deposit,one of the largest and oldest deposits in the Eastern Hebei ore concentration area,has made a significant contribution to China’s gold reserves.At present,exploration has reached a bottleneck.To address the critical issue of increasing reserves in the deeper parts,a systematic study was conducted based on the Trinity exploration theory and methods.A metallogenic prediction model was established to guide deep-edge exploration.Through large-scale structural and mineralization alteration mapping of typical sections and roadways in Jinchangyu Gold Deposit,the mineralizing structures,and structural planes were identified,and their spatial distribution was characterized.The relationship between the metallogenic geological body,mineralizing structures,structural planes,and mineralization features was further analyzed,leading to the preliminary construction of a Trinity metallogenic prediction model.The deep exploration target is suggested to focus on the V vein from Exploration Line 0 to 55,with elevations between -1 000 and -600 m.The peripheral exploration targets should be on the west side of the Ⅰ,Ⅲ,and Ⅳ veins.Preliminary engineering verification indicated that the Trinity metallogenic prediction model is effective,providing realistic guidance for continuous exploration and production in Jinchangyu Gold Deposit.
