摘　　要：铜绿山铜铁矿床是长江中下游铜铁多金属成矿带典型的接触交代矽卡岩型矿床之一,但经三十余年的开采,资源己是中度危机,寻找接替资源,迫在眉睫。通过对矿床成矿规律及地质、物化探异常特征的研究,认为矿床深部及外围仍具找矿潜力:根据矿体的赋存规律及以往建立的推断矿体有无延伸的模型分析,铜绿山矿床多个已知矿体还有较大延深(伸);根据异常特征结合成矿规律类比,矿区深部己知矿体的延伸部位,预测有尖灭再现矿体,或己知矿体的旁侧存在规模较大的新矿体(第二找矿空间);矿区外围找矿也具有良好找矿前景,根据前人在区内已知大中型矿床研究的基础上建立的资源量预测模型进行逻辑信息法统计预测,预测铜金属量达中型以上规模。The Tonglushan copper-iron deposit,being one of contact metasomatic skarn polymeatal deposit,is at medium risk for use up of its resource after 30 years mining.It s urgent to find its substitute.Based on analysis of ore formation principle,geophysical-geochemistry anomalies,the authors consider that there exist possible ores in the deeper and surrounding areas.After considering all the possibilities,the authors think that there exist a medium-scale copper deposit in the working area.
