Abstract:

Large and superlarge ore deposits are the results of supernormal accumulation of ore forming elements and their exploration is key for meeting the demands of mineral resources for national economy and society development. A combination of geodynamic background and metallogenic process studies with quantitative exploration and evaluation is an efficient approach. The geodynamic background study includes the following aspects: tectonic settings, crust-mantle structure and deep process, metallogenic petrological systems and regional thermo-fluid condition. For evaluating the preferential distribution and potential of mineral resources and predicting promising prospecting areas, it is specially important to reveal the deep Earth’s material and structure and geodynamic process of mass-energy transportation.

Key words: large-superlarge ore deposits, geodynamics, metallogenic process, Earth deep process, strategic key metal minerals
