| Abstract: | 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. |
