摘　　要：凹山矿田是我国东部重要的玢(斑)岩-浅成热液型铁铜金矿床矿集区。蓝辉铜矿床在凹山矿田马山硫铁矿床中首次发现,资源潜力较大。除赵玉琛对马鞍山地区火山岩铜金矿点进行研究;周涛发、毛景文等从凹山矿田铜金矿与A型花岗岩有关的氧化物-铜-金(铀)矿床成矿系统铜矿进行系统研究外,尚未有针对高硫型铜金进行过研究。研究高硫型铜金矿床成因,尤其通过蓝辉铜矿等指示矿物的发现和研究,不仅对矿田勘查意义重大,而且有利于探索斑岩型与浅成热液型矿的关系。本文试图通过分析矿体特征,探讨矿床成因,进而提出找矿方向。The Aoshan ore field is an important cluster of porphyrite(porphyry)-epithermal iron-copper-gold deposits in eastern China.The blue chalcocite ore deposit was first discovered in the Mashan pyrite deposit in the Aoshan ore field,with big potential of resources.In spite of a study of volcanic copper and gold deposits in the Ma'anshan area by Zhao Yu-chen,and a systematic study of oxides-copper-gold(uranium)ore-forming system’s copper deposits in view of their relationship with A-type granites in the Aoshan ore field by Zhou Taofa,Mao Jing-wen et al.,there has been no study ever made on the origin of high-sulphur copper-gold ore deposit.Study of the genesis of high-sulfur copper-gold deposit,especially through the discovery and study of indicator minerals such as blue chalcolite,is of great significance not only for the exploration of the ore field,but also for the exploration of the relationship between porphyry type and epithermal type.This paper tries to discuss the genesis of the ore deposit by analyzing the characteristics of ore bodies,and then single out the priority areas for prospecting.
