论地质作用中元素间的相关性及制约因素

本文把地质作用中元素间的相关性划分为曲线相关、准线性相关和线性相关三种类型;并在建立反映岩浆、沉积作用过程中元素间相关关系的数学模型及其它工作的基础上,详细讨论分配系数、源区成分和作用过程等方面对地质作用中元素间相关关系的制约作用。进而获得批式熔融、结晶分异、岩浆混合、化学沉积、碎屑沉积等过程中元素间呈线性和(?)线性关系的一般特征和应用前景。最后还给出La/Ce相关性的应用实例。

CORRELATIONS BETWEEN ELEMENTS FORMED IN GEOLOGICAL PROCESSES AND THE INFLUENCING FACTORS

Three types of correlations between elements (curve, para-linear and linearrelationship) have been attested in many geological bodies. On the basis of establishing mathematic models and describing behaviour relations of elements in magmatic and sedimentary processes, this paper principally discusses why and how partition coefficient, source composition and geological process influence the correlation between elements in geological bodies. Some general conclusions have been obtained. Finally,as a example, this paper researches the correlation of La and Ce which occurs extensively in many geological bodies.
