| Abstract: | Under definite conditions the capability of certain component escaping from certain phase within certain material system in earth space is defined as geochemical potential. This paper makes use of the gas model which illustrates the foundamental properties of geochemical potential.Geochemical potential interprets the following geological events related to geochemical factors: the origin of zonal arrangement of the earth and the sequence of the main ore minerals occurring in the ore deposits of Li, W, Cu, Pb, Zn, Hg, and Sb in connection with their molecular weight (or atomic weight); the relation between the contraction of tenors of the ore bodies (or veins) of W, ,Pb, Au, Cu, U and their positions in gravitional field Z; the relation between concentration of rich ores and the velocity of ore fluids in their metallogenesis as indicated by the iron ore deposits of Anshari type in the Anshan area and some skarn type, copper bearing sand stone in sedimentary stage, the process of secondary enrichment of copper deposits, the copper deposits occurring in metamorphic systems, some auriferrous quartz veins, as well as wolfram quartz veins.Function of geochemical potential opens the way for finding the constancy of geochemical potential and illustrating the theory of geochemical potential field. |
