Study of mineralization belts not only reflects research results of regional metallogeny, but offers the direct basis for determination of geological prospecting and exploration. It is of essential meaning to use the national assessment data of mineral resource potential to re define metallogenic belts and deploy next investigation plan in China. The division of mineralization belts is not only based on regional tectonic environment and evolution but on spatial temporal distribution of ore deposits and a large number of metallogenic data such as geophysical and geochemical and remote sensing results. This scientific classification for mineralization domains and provinces finally provides more direct and practical information for prospecting in these metallogenic belts.In accordance with t the national prospecting planning, the study did some optimal ordering for the metallogenic belts, and this will give the direction for future geological investigation and will greatly improve prospecting breakthrough in the metallogenic belts. Based on previous results for 23 mineral species and geophysical and geochemical anomalies data in key mineral resources bases, and the latest 90 three level metallogenic areas, this study has determined 26 metallogenic belts of key solid mineral resources all around China, among which ten critical deployment areas were preferentially deployed.
