摘　　要：通过对广东大顶铁矿田南部矿带多金属矿床地质特征的综合研究,总结和探计了该区多金属矿床的控矿因素、成矿规律及矿床成因。经研究表明,该区钨锡矿床为岩浆热液接触交代矽卡岩型矿床,铁矿床为海相沉积-热液改造型变质矿床,铅锌银矿床为岩浆热液交代充填型矿床。This paper deals with ore control factors, metallogeny and ore genesis of the polymetallic deposits in the southern zone of the Dading iron field, Guangdong. The study shows that W-Sn deposits in this region belong to skarn type, while Fe deposits are sedimentary-reformed type and Pb-Zn-Ag deposits are hydrothermal metasomatic-filling deposits in origin.
