摘　　要：云南富民东村钛铁砂矿品位高、厚度大,具有良好的找矿前景,矿体产于含钛铁辉长岩基性侵入体风化壳及附近地形有利部位。通过对研究区地质特征、矿床成因、控矿因素、找矿标志等分析研究认为,区内钛铁砂矿为基性侵入岩体风化形成,钛铁砂矿的品位、厚度与辉长岩的风化程度有关,风化壳越厚,地形越有利,矿体厚度越大、品位越高。The thickness and ore grade of Dongcun Ilmenite Placer are rich,it has a good prospecting prospect.The deposit is confined to the gabbro and advantaged topographic.The placer occurs in the weathering crust of the gabbro.This paper has a discussion on geological characteristics,ore gensisi,ore control factors and ore criteria of the ilmenite placer.The study indicates that the ilmenite ore deposit is formed by weathering of gabbro,thickness of the orebody and ore grade are in close relation with weathering crust thickness and topography.
