Abstract:

Geosciences are in the era of information science and informationization when as modern geosciences driven by the big data strategy are booming, and geochemistry has come into being in modern times as having the natural attribute of structured information science. The overall idea of conducting applied geochemical research, based on the big data science from informationization to modeling to intelligentization, is as follows: foremostly, build the information system on the basis of the geochemical big data; secondly, establish the zonal enrichment model of ore-forming geochemistry and the cumulative effect model of ecological geochemistry using the method and theory of the earth system science; thirdly, use intelligent system and techniques to analyze, judge and predict large amount of geological and geochemical nonlinear phenomena according to patternized thinking; and lastly, based on the geochemical research and application, evaluate and solve the important problems concerning the resources and environment which will influence the nationwide socioeconomic development. Big data and earth system science are two pillars of the applied geochemical research. Aimed at solving the main problems facing us today, this paper discusses the geochemical big data informationization, information modelling, model intelligentization, etc. The key point is to construct the intelligent system, with the geoscientific model as the main body, and study the scientific problems of metallogenic system and ecosystem. The world socioeconomic development and resources-environmental processes are in the age of globalization, therefore, we must look at the ore-forming geochemistry and ecological geochemistry from the perspective of global resources allocation and global environmental changes. Nowadays, the key computer techniques are becoming increasingly mature and perfect, and the frontier studies of the intelligent technology are making breakthroughs continuously. Furthermore, it is a great advantage for geochemistry to have the attribute of structured information science. All these contexts indicate that we have the preconditions to establish the geochemical big data information science such that it may stand out from the field of geosciences and become an emerging research paradigm advancing continuously with broad vision.
