Conceptual model of deep-penetrating geochemical migration.

Deep-penetrating geochemistry is a new branch of geochemistry initiated for looking for concealed ore deposits.Its theoretical framework consists of several consecutive elements:mechanism of migration of elements from deeply buried deposits to the surface→modes of occurrence of elements in overburden at surface→geochemical anomaly patterns.With respect to the mechanism of migration of elements from deeply buried deposits to the surface,three traditional migration models are summarized they are the models of ionic diffusion,groundwater dissolution and dispersion and electrochemically-induced dispersion.Based on the latest research results,the new conceptual models of earthgas streaming and multi-agent dispersion are proposed.The systematic summary and proposition of these models have great significance for the establishment of the theoretical basis of geochemistry and study of 3D element dispersion model of concealed deposits.
