The earth is a complicated system, and it has been continuously moving differentiating and evolving since it had been formed. Not only has the earth layering structure, but it has vertical movement of materials. The movement is prompted by the mechanism of force and heat of the centrifugal force to be formed by the rotation and revolution of the earth, and difference of temperature, pressure, density, viscosity and velocity in the between core and mantle, and radioactive heat, et al. The expressive means of the mechanism of force and heat are the precesses of mantle plume and mantle fluid. Not only are ore-materials of core and mantle carried directly into crust, but ore-materials of crust are activated and accumulated into proper location by the mantle fluid having the supercritical nature.

地球是一个复杂的系统，自形成以来，一直处于不停地运动、分异和演化过程；它不仅存在着圈层结构，而且伴随其自转和公转的离心力，以及核幔间的温度差、压力差、密度差、粘度差、速度差和放射性蜕变热等动热机制，同时存在着以地幔柱和地幔流体作用方式的物质垂向运动；这一过程，不仅直接向地壳带入核幔成矿物质，而且通过流体自身的超临界性质，将沿途活化已有初步富集的成矿物质转移至地壳适宜部位集中成矿。

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.
