摘　　要：根据最近的勘查成果,从控矿构造、赋矿地层阐述大顶铁矿的成矿地质条件,结合地表和钻孔揭露矿石矿物特点、矿物组合规律、围岩蚀变以及矿体空间展布特征,探讨本区铁矿成矿地质因素、找矿标志以及找矿规律。大顶铁矿为含锡磁铁矿矽卡岩型矿床,主要成因为高温热液接触交代。Based on the recent investigation,the paper expounds the ore-forming geological conditions of Dading iron deposit from the ore controlling structure and host strata. Combined with ore mineral characteristics,mineral assemblages,wall rock alteration and ore regularity of spatial distribution characteristics of iron ore in the area,the metallogenic factors,prospecting criteria and prospecting pattern are discussed in this paper. This iron deposit is Sn magnetite of skarn type,mainly contact metasomatic-hydrothermal type.
