| Abstract: | Phosphatic series of Baiguoyuan in Yichang is located in the northwest of the Huangling anticline, which is a part of Yichang phosphate. The phosphorite was formed in the transgression of the Sinian Doushantuo period. The enrichment phosphorus lies in the Zhang cun-ping layer of Doushantuo Formation. From geochemical study on the profile of Baiguoyuan, we obtained the following conclusions:(1).The rich layer of phosphorite in Baiguoyuan is mainly composed of phosphate mineral, which is constituted by P2O5 a... |
