摘要
六股水磷矿床赋存于下寒武统麦地坪组,包含2个磷矿层、6个磷矿体。矿体水平延伸1200～2700m,均厚1.3～4.88m,深部延深大于120m。矿石类型有块状及白云质条带(条纹)状2种磷矿石,P2O5平均品位29.42%。稀土元素总量低,分布模式呈轻稀土富集型。矿床为生物化学沉积成因,磷经历了复杂的富集过程。
With two phosphorus ledges and six orebodies,Liugushui phosphorus deposit was hosting in the Cambrian Maidiping group.The orebody are from 1200 to 2700 meters in horizon and with the thickness of from 1.3 to 4.88 meters,deeping into 120 meters.There are massive and dolomitic banded types of rock phosphate,the average grade of P2O5 is 29.42%.Light rare earth elements are less and the formation cause of deposit is biochemistry sedimentatary.The phosphorus came through the complex enrichment process.
