鄂西磷矿的分布与产状受神农架背斜和黄陵背斜控制,为荆襄式晚震旦世沉积型磷块岩矿床。受浅海台地台坪亚相,磷块岩、泥(页)岩、白云岩含磷建造和水下隆起古构造等控制。晚震旦世陡山沱期磷矿评价标志为:上震旦统陡山沱阶;浅海台地台坪亚相;磷块岩、泥(页)岩、白云岩含磷建造;成矿地段陡山沱阶厚度一般小于200m,最佳150~50m;水下隆起带;磷块岩矿床一般分布在冰碛砾岩为0m的区域;含磷建造等深线一般小于1000m。评价结果表明,荆襄、宜昌、新华、神农架和保康磷矿区的深部及外围具有较好的资源远景,资源潜力大。
The distribution and occurrence of phosphate rock in western Hubei are controlled by the Shennongjia anticline and the Huangling anticline, which are Jingxian late Sinian sedimentary phosphate rock deposits. It is controlled by sub-facies of Taiping, phosphorite, mudstone, dolostone-bearing phosphate and dolostone in the shallow sea platform. The late Sinian Doushantuo period phosphorite appraisals are as follows: Upper Sinian Doushantuo terrace; shallow platform Taiping subphase; phosphorite, mud (page) rock, dolomite phosphorus; steep mineralization The thickness of the mountainous Tuoji is generally less than 200m and the best is 150 ~ 50m. The underwater uplift zone and phosphorite deposit are generally distributed in the area where moraine conglomerate is 0m. The isobaric depth of phosphorus-bearing construction is generally less than 1000m. The evaluation results show that the deep and the periphery of Jingxiang, Yichang, Xinhua, Shennongjia and Baokang phosphate mining areas have good prospect of resources and great potential for resources.
