磷和磷酸盐是主要的农业肥料之一,并且还广泛地应用于冶金、化学、医药和国防等部门。因而,加速开发和利用磷矿资源为促进我国四个现代化的早日实现是具有重要战略意义的。我国磷矿床的类型比较齐全,内生、外生和变质的磷矿床都有所发现。从成矿时代来说,从太古代到现代的磷矿床也都有发现。但是,从已知磷矿床的地理分布情况来看,则主要分布在我国中南和西南地区。 Phosphorus and phosphate are among the major agricultural fertilizers and are also widely used in metallurgy, chemical, pharmaceutical and defense industries. Therefore, it is of strategic importance to accelerate the development and utilization of phosphate rock resources to promote the early realization of the four modernizations in our country. The type of phosphate deposits in China is relatively complete, and all endogenesis, exogenous and metamorphic phosphate deposits have been discovered. From the mineralization era, from the Archean to modern phosphate deposits have also been found. However, from the known geographical distribution of phosphate deposits, it is mainly distributed in China’s south-central and southwestern regions.
