21st Century’s roadmap for exploration geochemistry in China

Abstract：Recent advances of exploration geochemistry in China are reviewed including (1) In-depth study of the tremendous amount of data obtained in past geochemical mapping projects for: (a) better planning of future exploration in China. (b) pediction of ore reserves potential by using the idea of minerelization coefficient, general, regional, and spcified (MCG, MCR & MCS). (c) new idea and methodology for searching economic & independent Se, Te, Ga, Ge, In, Tl deposits. (d) understandings of the evolution of S. China tin and tungsten granites from Archaean to Yanshan period. (e) calculation of the fractionation coefficients to describe the behavier of Pt, Pd, Os, Ru, Ir, Rh during and after the formation of SW China mantle plume, (2) advancement of 76 element analytical scheme and new data quality monitoring procedure using the idea of virtualized standard maps. (3) New idea and methodology in deep penetrating Geochemistry including micro-sieving method and micro-phase analysis. (4) new program of regional geochemistry with overburden drilling. (5) Eco-agro-evironmental mapping program to cover whole China. (6) New idea and methodology for geochemical mapping in global scale based on the fractal self-similiarity principle controlling the distribition of elements in diff kinds of sediments. In order to widen the scope of exploration geochemistry in 21st century 12 big geochemical programs are suggested, all based on the ideas that maping in diff scales and of nearly all elements in the periodic table provides the foothold for the advancement of exploration geochemistry in the 21st century, that close integretion of mapping, research, exploration and engeieering (drilling, trenching, etc) are necessery, for increarsing the success of discoveries, that establishment of a global geochemical mapping research center in IGGE, China with our new mapping cocept will promote to get a global picture of elements distribution in earlier days.
