用丰度关系法估计岩浆分离结晶过程的物理化学参数

APPLICATION OF TRACE ELEMENTS ABUNDANCE RELATIONSHIP TO ESTIMATION OF PHYSICO-CHEMICAL FACTORS IN MAGMA FRACTIONAL CRYSTALLIZATION

该文简要介绍了岩浆分离结晶过程中微量元素丰度关系式。讨论了用丰度关系法估计岩浆分离结晶过程中的主要物理化学参数,如元素总分配系数、元素在原始岩浆中的初始含量、分离结晶度等的方法和实际应用。

This paper briefly introduces the formula of abundance relationship of trace elements in magma fractional crystallization, discusses the estimation of physico-chemical factors, such as bulk partition coefficient (D), the initial content of elements in primary magma and degree of fractional crystallization, in terms of the abundance relationship. It gives also some examples of application. This method improves the existing method in which there are some unknown factors in the formula, and there are some suggestion to some elements, such as the higher compactible or imcompactible elements. So, this method estimates the physico-chemical factors and their variation in magma fractional crystal-lizationion more objectively, more perceivably. This is a new approach of inverse technique estimating theperameters of magmatic fractional crystallization process.
