摘　　要：百顺矿田位于广东南雄,通过野外调研工作,对矿区围岩蚀变岩石学和地球化学特征进行了系统的研究,结合前人对该地区的研究成果,对烟筒岭的围岩蚀变类型和矿化类型做出了以下总结:本地区的蚀变主要沿着断裂两侧展布,受断裂构造控制。其中以面状发育的白云母化,长石化和绿泥石化最为广泛,其次为水云母化,碳酸盐化,黄铁矿化和萤石化以及赤铁矿化等。与成矿关系密切的蚀变类型为绿泥石化,水云母化和赤铁矿化。Baishun ore field is located in Nanxiong,Guangdong Province.Through field investigation,the petrological and geochemical characteristics of surrounding rock alteration in the mining area are systematically studied.Combined with the previous research results in this area,the following conclusions are made:the alteration in this area is mainly distributed along both sides of the fault and controlled by the fault structure.Among them,muscovite,long petrochemical and chloritization are the most widely developed,followed by hydromica,carbonation,pyrite,fluorite and hematitization.The alteration types closely related to mineralization are chloritization,hydromica and hematitization.
