摘　　要：化皮峪矿床为一小型矽卡岩型多金属矿床,为研究其地质特征、成因及区域成矿潜力,采用了地质路线调查、采样化验、区域成矿背景研究、物化探分析等方法并得出以下结论:(1)化皮峪矿床共包括2条矿体,矿种为铁、铅、锌,矿体平均厚度1.40 m,TFe平均品位为41.03%,mFe平均品位为38.99%,Zn平均品位2.19%,Pb平均品位为0.42%。(2)从成因类型看,化皮峪矿床成为矽卡岩型多金属矿床。(3)将本溪桥头镇-草河城镇一带划为矽卡岩型多金属找矿潜力区。另外还应多注意石炭系地层与中酸性岩浆岩的接触部位。这将对本溪地区乃至整个太子河坳陷内部的多金属矿床的找矿工作具有一定意义。Huapiyu deposit is a small skarn ore polymetallic deposit.We use geological route investigation,sampling test,regional metallogenic background,geophysical and geochemical exploration and analysis in Benxi area to study the geological characteristics,genesis and regional metallogenic potential of Huapiyu polymetallic deposit.The following conclusions are drawn:(1)Huapiyu deposit include two orebodies,iron,lead,zinc,the average thickness of the orebody is 1.40m,the average TFe grade is 41.03%,the average MFe grade is 38.99%.The average Zn grade is 2.19%,and the average Pb grade was 0.42%.(2)From the perspective of genetic type,Huapiyu deposit is a skarn type polymetallic deposit.(3)The area between Benxi Qiaotou Town and Caohe Town is classified as a skarn type polymetallic metallogenic potential area.In addition,more attention should be paid to the contact site between the Carboniferous strata and the intermediate-acid magmatic rocks.This will be of great significance to the prospecting of some polymetallic deposits in Benxi area and even the whole Taizihe depression.
