摘要
宜昌磷矿属于扬子地台区陡山沱成磷矿期,磷块岩主要形成于鄂西陡山沱期鄂中台地边缘叠层石礁相和开阔—局限海台地相的环境中。鄂西震旦纪陡山沱组地层剖面上通常可以划分出四个磷矿层位,具有工业价值的磷矿层主要为Ph1、Ph2。对宜昌蒋家湾—树崆坪磷矿以及神农架巴桃园含磷矿岩系的研究表明,与磷矿层陡山沱组中的黑色岩系密切相关,磷的富集除了正常海相沉积之外,生物与热水沉积也起到了较为重要的作用。宜昌磷矿是湖北省优势矿种,研究其地质特征及成因规律性对该地区磷矿勘探的中深部找矿工作具有重要意义。
On the stratigraphic profile of Doushantuo Fm Sinian Period usually can divided into four phosphorus horizons,in which the Ph1、Ph2 phosphatic bed have industrial value.After researching the phosporus-containing rock series of Shukongping-Bataoyuan,the black rock series have closed relationship with each other in Doushantuo Fm.It also shows that the enrichment of phosphorus not only depend on marine facies deposit,but also on biology and hot-water deposit.Yichang phosphorus is a dominant mineral in Hubei province,so it is significant for deep prospecting about researching its geological characteristics and genetic law.
