磷灰石在岩浆中的溶解行为有助于理解熔体的演化、微量元素如REE、U、Th、Sr等的分异和地幔交代流体的形成。本文综述了硅酸盐熔体中温度、熔体成分(Si O2、Ca O、Al2O3、S等)和碳酸盐熔体中温度、Ca O含量等对磷灰石溶解度的影响,介绍了已建立的溶解度模型以及采用模型成功解释实际成岩成矿过程的例子。在概述研究进展的基础上,指出了压力、卤素和高压流体等对磷灰石溶解行为影响的研究的不足。
The dissolving behavior of apatite in magma can help to understand the evolution of the melt, the differentiation of trace elements such as REE, U, Th, Sr and the formation of mantle fluid. This paper reviews the influence of temperature, melt composition (Si O2, CaO, Al2O3, S, etc.) and the temperature and CaO content of silicate melt on the solubility of apatite. The established solubility model and the successful interpretation of the actual diagenetic mineralization process using the model. Based on the research progress, the shortage of the research on the influence of pressure, halogen and high pressure fluid on the dissolution behavior of apatite was pointed out.
