摘要
为梳理矿区地质特征,进行成矿构造深部预测,解决矿区深边部找矿问题,以志木山金矿区矿床为研究对象,收集、梳理前人的研究成果,总结矿区构造、岩浆岩、蚀变、矿体等特征,结合野外地质填图、地球物理特征等信息,主要采用物探激电中梯研究方法,对矿区地球物理异常特征、地质特征、找矿前景等进行全方面分析,探讨矿床成因、控矿因素、富集规律等,总结找矿标志。研究结果表明,主矿床产于剪切断层破碎带的主构造中,并受三期构造控制,研究圈定了3处高极化率和视电阻率物探综合异常区,发现蚀变带和矿脉8条,具有潜在的找矿突破价值,可为该区域金矿床找矿勘查工作提供一定的参考和指导。
In order to sort out the geological characteristics of the mining area,carry out the prediction of metallogenic structure depth,and solve the problem of prospecting at the deep edge of the mining area.Taking the deposit of Zhmushan gold mining area as the research object,collecting and combing the previous research results,summarizing the characteristics of the structure,magmatic rock,alteration and orebody of the mining area,combining the field geological mapping and geophysical characteristics and other information,and mainly using the geophysical exploration induced electric ladder research method,the geophysical anomaly characteristics,geological characteristics and prospecting prospects of the mining area are comprehensively analyzed.The genesis,ore-controlling factors and enrichment rules of the deposit are discussed,and the prospecting signs are summarized.The results show that the main deposit occurs in the main structure of the shear fault fracture zone and is controlled by the third-stage structure.Three comprehensive geophysical anomalies with high polarizability and low resistivity have been delineated,and eitht alteration zones and veins have been discovered,which have potential prospecting breakthrough value and can provide certain reference and guidance for the gold deposit prospecting and exploration in this area.
