摘　　要：马厂地区是庐江-滁州成矿带是一个典型地段,地表有数十个古采坑,找矿潜力巨大。东孙家铜矿作为该地区开采中的矿山,研究其成矿模式为马厂地区的成矿模式研究提供指导意义。通过对马厂地区地质特征进行研究,对东孙家铜矿勘探成果分析总结,结合前人的一些研究成果,提出东孙家铜矿新的成矿模式。结果表明,东孙家铜矿的主要成矿模式为层控矽卡岩型和多成因U型,对马厂地区乃至滁州—花山—黄栗树—马厂成矿带寻找铜、金矿床具有指导意义。Machang area is a typical area of Lujiang-Chuzhou metallogenic belt,with dozens of an⁃cient mining pits on the surface and great prospecting potential.Dongsunjia copper mine is a developing mine in this area,the study of its metallogenic model provides guidance for the metallogenic model in Mach⁃ang area.By studying the geological characteristics of Machang area,the exploration results of Dongsunjia copper mine are analyzed and summarized,and a new metallogenic model of Dongsunjia copper mine is put forward.The results show that the main metallogenic models of Dongsunjia copper deposit are strata-con⁃trolled skarn type and multigenetic U-type,which is of guiding significance to the search for copper and gold deposits in Machang area and even Chuzhou-Huashan-Huanglishu-Machang metallogenic belt.
