元素迁移的分维结构、级序路径及共轭地球化学异常存在的理论依据

FRACTAL STRUCTURE AND HIERARCHICAL PATHS OF ELEMENT MIGRATION AND CONJUGATE GEOCHEMICAL ANOMALIES

微量元素在矿源岩（层）中迁移遵循严格的级序路径，并且存在两种迁移倾向。迁移的结果图象是一分维结构。两种共轭地球化学异常出现的有利环境是温度高度反差地区和大断裂系及其附近。

The migration of trace elements in source rocks follows a hierarchical path sequence, starting with crystals, through intergranular surfaces, various fissures and the like, and finally joining large scale faults filled with running aqueous solutions.There are two tendencies for trace element to migrate. One is from within bulk solid cells to various sinks, and the other from high temperature fields to lower ones. The resultant migration pattern is a fractal structure. Diffusion may play a key role in element reactivation, which is essentially a kind of oriented short-range mass transport within bulk solid cells and lower rank sinks. Conjugate geochemical anomalies are the inevitable result of a closed geochemical system. Two geological environments are especially promising in development of large scale conjugate geochemical anomalies: areas with highly contrast temperature distribution, and major fault zones and their associated surroundings.
