坦桑尼亚石墨矿资源较为丰富,研究其石墨矿资源特征及资源潜力,对坦桑尼亚及其周边地区开展石墨矿资源选区评价和勘查开发具有重要意义.石墨矿床主要分布于其东北部、中部和东南部地区.常见的石墨矿床类型主要有:岩浆岩型、变质岩型和风化沉积型,其中变质岩型石墨矿床具备较大的经济价值.通过对坦桑尼亚的区域成矿地质背景、石墨矿床的成矿类型、分布和规模进行研究,初步认为坦桑尼亚东南部的石墨成矿带延续至莫桑比克境内,该成矿带上石墨远景资源量巨大,具备较大的找矿前景.%Graphite ore resources are rich in Tanzania,the great significance of studying of the graphite ore resource selection evaluation and exploration in Tanzania and its surrounding area.Graphite deposits are mainly distributed in the northeast,central and southeastern regions.The main types of graphite deposits are magmatic rock type,metamorphic type and weathering type,among which the metamorphic type graphite deposit has great economic value.The regional report shows that the graphite-bearing belt is extended into Mozambique.Research on types and scale of graphite deposits,provides the reference for graphite prospecting in or around Tanzania.
