摘　　要：大顶山磁铁矿床位于泸沽花岗岩体外接触带,铁矿体赋存于中元古界登相营群夕卡岩化大理岩中,呈似层状、透镜状产出,矿体与夕卡岩化大理岩关系密切;大顶山磁铁矿床是泸沽花岗岩体侵位过程中沿层交代的产物,其矿床成因属接触交代型矿床。Dadingshan magnetite ore deposit is located in outer contact zone of Lugu granite body. The iron ore bodies occur in layeroid body or lens in the skarnized marble of Middle Proterozoic Dengxiangying group and are closely related to the skarnized marble. Dadingshan magnetite deposit is the product of metasomatism along bed plane during emplacement of the Lugu granite
