磷灰石是普遍存在于岩浆岩和变质岩中的副矿物。它其有十分稳定的晶体化学结构。利用磷灰石中保持良好的U、Th、Pb和Rb、Sr等元素测定同位素年龄,可反映出早期地质事件的时间。值得重视的是,磷灰石在锶同位素地质学和年代学的应用中将具有重要的理论意义和明显的经济效果。磷灰石中富含F、Cl、CO_2和H_2O等挥发组份,常用来研究岩浆的性质和成岩的物理化学环境。因此,能否有效地获取纯净的磷灰石单矿物,已成为地质科研人员极为关注的问题。
Apatite is a sub-mineral commonly found in magmatic rocks and metamorphic rocks. It has a very stable crystal chemical structure. Determining the age of isotopes using well-preserved elements such as U, Th, Pb and Rb, Sr in apatite can reflect the time of early geological events. It is worth noting that apatite will have important theoretical significance and obvious economic effects in the application of strontium isotope geology and geochronology. Apatite is rich in F, Cl, CO_2 and H_2O and other volatile components, commonly used to study the nature of magmatic and diagenetic physical and chemical environment. Therefore, the availability of pure apatite mono-mineral has become a very important issue for geoscientists.
