河南省吉家洼金矿外围F1含矿带中深部金矿成矿潜力预测

Mineralization Potential Forecast for the Central-deep Part of F1 Surrounding Ore- bearing Belt in Jijiawa Gold Deposit

吉家洼金矿是熊耳山金矿田内的一中小型金矿,经建矿开采和探采结合,已持续生产十多年,累计查明金5 379 kg。笔者在系统总结研究以往金矿床的浅表部成矿特征和成矿规律的基础上,认为吉家洼金矿外围F1含矿带的中深部成矿具有半隐伏-隐伏成矿特征。通过少量验证工程的实施和中深部成矿潜力及隐伏矿资源量预测,可获金9 874 kg,表明F1中深部具备找矿潜力,应继续开展中深部找矿的验证工作。这将对该区域深部找矿及寻找隐伏矿具有重要意义。

Jijiawa gold deposit is one of the middle-small gold deposits in the Xiongershan orefield,which has continued to produce more than a decade after the construction of mining and the combination of exploration with mining,and the cumulative total gold is 5 379 kg.On the basis of systemic researching and summing up the metallogenic characteristics and metallogenic regularity of the previous superficial gold deposits,the authors suggest that the central-deep part of F1 surrounding ore-bearing belt in Jijiawa gold deposit is of a half-concealed-concealed mineralization characteristics.Based on a small amount of exploration work,metallogenic prognosis and middle-deep mineralization potential of F1,the reserves could reach 9 874 kg.Therefore,the central-deep part of F1 belt has great potential prospecting,and should be continued to do the prospecting work,which will has great significance for regional prospecting and finding buried deposits.
