摘　　要：中国沉积磷矿床主要分布在扬子地块东南缘与西缘,华北地块南缘和西缘;沉积磷矿主要赋存在震旦系陡山陀组、下寒武统梅树村阶、古元古界上部滹沱群和古元古界顶部榆树砬子组等含磷岩系中.根据成矿条件,矿石组合特征划分为开阳式、荆襄式、昆阳式、什邡式等11个类型.通过含磷岩系分布,成矿规律的综合分析,划分出28个聚磷区,对有远景的聚磷区进行了资源潜力评价.Sedimentary phosphatite deposits are mainly distributed over the Southeastern and western Margin of Yangtze Block, the southern and western Margin of North China Block. Sedimentary phosphate rock mainly existed in the Phosphate-Rocks of Simian Doushantuo formation, the Meishucun stage of the lower Cambrian, the Hutuo formation of the upper Palaeoproterozoic, the Yushuzi formation of the roof of Palaeoproterozoic and so on. There are 11 forms which has been classified according to ore-f0rming conditions and minerals association characteristics, such as Kaiyang, Jingxiang, Kunyang, Shifang and so on. By analogy with the distribution of phosphate-rocks and comprehensive analysis of mineralization law, this paper has outlined 28 phosphate-rich areas and made the resource potential evaluation.
