进入21世纪中国化探发展路线图

笔者回顾了近年来中国化探的一些理论与方法技术上的重大新进展,立足于地球化学填图基础上的矿集区、多元素异常集结区与地球化学块体理论,利用地球化学资料进行矿产资源潜力评价与稀有分散元素独立成矿的可能性评价,利用地球化学资料进行成矿岩体演化与中国西南大地幔柱的初步研究,这些探索性的研究均取得了令人鼓舞的成就。化探方法技术的应用成果显著,如地球化学填图与矿产勘查一体化,多元素分析与分析质量监控方法不断完善外来物覆盖浅钻取样,深穿透地球化学方法,全国生态、农业、环境地球化学调查,全球地球化学填图方法研究等。在回顾近年化探成果的基础上,提出中国化探在21世纪的发展,整体思路是立足于地球化学填图及地球化学填图与矿产勘查一体化。需要有将研究、填图、调查、勘查、工程一体化的大科学计划。提出了涉及地球化学填图、矿产勘查与综合利用、能源勘查、生态环境调查、全球变化研究等的12个重点发展方向。

21st Century's roadmap for exploration geochemistry in China

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 microphase 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.
