| Abstract: | Abstract Haizhou-type phosphate deposits stand as a sedimento-metamorphic deposit,occuring in such formations of middle Proterozoic age as Jinping of Haizhou group,Shuangshan of Feidong group, Liuping of Susong group and Qijiaoshan of Hongan group. Depositions of the phosphate rocks were controlled extremely by lithofaciespaleogeographical condifions, madly taking place in the shallow areas of the tablelands alone the margins of basins. |
