摘要
磷元素在地壳发展过程中，随磷矿成矿作用不同阶段物化条件改变而变化。将成矿划分为沉积、变质及改造三阶段。成矿时代为中元古代早期。由沉积、变质、混合岩化交代和风化淋滤作用，使磷质活化，在一定空间富集成矿。
In the development procedure of the crust, the element phosphorus varies in pace with the change of physical and chemical conditions in the different phases of phosphoric mineralization. Its mineralization can be divided into three phases, deposition phase, metamorphism phase and reformation phase. The mineralization epoch is the early period of mesoproterozoic Era. Due to the deposition, metamorphism, migmatization and weathering infiltration, phosphoric substances are remobilized, concentrating and mineralizing in a certain space.
