摘　　要：矿区大地构造位置上扬子古陆块二级构造单元,扬子陆块南部被动边缘褶冲带三级构造单元之凤岗南北向褶断区及黔中隆起四级构造单元北缘洋水背斜东翼深部。矿床属外生沉积类型磷矿床。矿层中的主要有用组分是P2O5含量高,伴生有益组份碘(I-)和氟(F-)均有综合利用价值。区内磷矿石是目前世界少有、国内唯一不经选矿就可直接用于生产高浓度磷肥的优质原料。具有较大的开发利用价值。The mine area locates in secondary tectonic unit of Upper Yangtze oldland, and situated Fenggang NS fault-folded zone on the passive marginal fold-thrust belt of southern Yangtze landmass, east limb deep part in Yangshui of qianzhong uplift Ⅳ tectonic unit.The deposit belongs to the sedimentary type.The main useful group in a mine is the high content of P205, associated with beneficial components of iodine （I-）and fluorine （F-） have comprehensive utilization value.Phosphate ore in the region is currently the world＇s few ,the only domestic can not be directly used for the production of high concentration phosphate fertilizer.It has great value of development and utilization.
