安徽省枞阳县拔茅山铜矿位于长江中下游铁、铜、金(硫)成矿带中段,庐—枞(庐江—枞阳)火山岩盆地矿集区南部,目前探明铜金属量13 549.84 t,平均品位0.98%,为一小型铜矿床。由于基础资料的限制,多年来该矿床的地质成因一直无法明确。为此,结合区内地质勘探成果,对成矿地质背景、矿区及矿床地质特征、矿床成因进行了分析,认为该矿床应属斑岩型铜矿床类型。在上述分析的基础上,系统总结了找矿标志,对于该区进一步开展地质勘探工作有一定的参考价值。
The Bumoushan copper deposit in Zongyang County, Anhui Province is located in the middle part of the iron, copper and gold (sulfur) metallogenic belt in the middle and lower reaches of the Yangtze River and is located in the south of the Lu-Zong (Lujiang-Zongyang) volcanic basin. The current proven copper metal content is 13 549.84 t, the average grade of 0.98%, as a small copper deposit. Due to the limitation of basic data, the geological cause of this deposit has not been clear for many years. Therefore, combined with the geological exploration results in the area, the geological background of mineralization, the geological characteristics of ore area and deposit, and the genesis of deposit are analyzed. It is concluded that the deposit belongs to the type of porphyry copper deposit. Based on the above analysis, the ore-prospecting symbol is systematically summarized, which is of certain reference value for further geological exploration work in this area.
