摘要
宜昌磷矿东部整装勘查区位于湖北省远安县、保康县及夷陵区交界处,区内磷矿层赋存于下震旦统陡山陀组,发育有Ph13、Ph21、Ph22三层工业磷矿层,矿体埋深174~1710m,沿走向长约26180m,沿倾向宽约9190m,共提交工业磷矿石推断及以上资源量18.47亿t;宜昌磷矿的矿床类型为沉积型,成矿时代为新元古代早震旦世陡山沱期,成矿作用主要为胶体化学作用,其次为生物化学作用,矿体受含矿地层控制,在特定的岩相古地理环境下富集成矿;本文在整装勘查区东部空白区圈定吴家岭、刘家坪等4个找矿靶区,预测可新增资源量10亿t以上,找矿潜力巨大。
The eastern assembly exploration area of Yichang phosphate mine is located at the junction of Yuan'an County,Baokang County and Yiling District of Hubei Province,where the phosphate layers are deposited in Duoshantuo formation of the Lower Sinian system,and there are three-layer industrial phosphate layer of Ph13,Ph21 and Ph22,which is about 26180m long along the strike,about 9190m wide along the trend,and the buried depth of the ore body is 174.05~1710.20m.A total of 1.847 billion tons of resources of industrial phosphate ore with the inferred levels and higher levels were submitted.The deposit of Yichang phosphate rock is sedimentary type,and the metallogenic period is neoproterozoic,and the metallogenic action is mainly chemical effects of colloids,followed by biochemical action.Ore bodies are controlled by ore-bearing strata,which is enriched in the specific lithographic paleogeographic environment.In this paper,four prospecting target areas including Wujialing and Liujiaping are delineated in the eastern blank area of the integrated exploration area,and it is predicted that the new resources can be increased by more than 1 billion tons,and the prospecting potential is huge.
