湖北大冶铜鼓山地区成矿地质条件及找矿前景探讨

The metallogenic geological conditions and prospecting predictionin Tonggushan area,Daye,Hubei Province

通过对铜鼓山地区已知矿床控矿因素研究,已发现的矿化体多赋存于接触带及岩体内部的裂隙中,中酸性侵入岩、断裂、碳酸盐岩地层是区内有利成矿地质因素。通过综合分析该地区有利的成矿地质条件特征,认为铜鼓山地区具有形成斑岩型、矽卡岩型铜多金属矿的前景。区内下一步找矿工作应注重对区内已知矿床的成矿规律研究,对已知矿床深边部的找矿潜力进行评价,推动本区地质找矿工作。

By researching on the metallogenic regularity of known deposits in the Tonggushan area,those discovered ore bodies are mostly founded in the contact zone and the cracks inside the intrusion.Medium-acid intrusive rocks,faults,and carbonate rock formations are favorable geological factors for mineralization in the area.Through comprehensive analysis of the favorable metallogenic geological conditions in the region.it has the prospect of forming skarn-porphyry copper polymetallic deposits in Tonggushan area.In the future,we should focus on the research of the metallogenic regularity of the known deposits,evaluate the prospecting potential on the depth and side of the known mineralization points,then promote the geological prospecting work in this area.
