全国重要固体矿产重点成矿区带划分与资源潜力特征

Division of Major Mineralization Belts of China's Key Solid Mineral Resources and their Mineral Resource Potential

成矿区带是区域成矿规律研究成果最集中反映,同时也是地质找矿勘查部署最直接依据。利用全国重要矿产潜力评价成果重新厘定我国重要成矿区带,部署我国重要成矿区带有重要实际价值。成矿区带划分一方面要以区域构造环境及演化为纲,对成矿域、成矿省进行科学划分;同时要研究成矿本身时空分布规律,研究矿床的多元地物化遥等成矿信息,使得成矿区带符合成矿实际,能够直接找矿。部署区带是根据国家找矿工作部署出发,对成矿区带进行优选排序,具有引导导向作用,往往也能大大促进部署区带地质找矿突破。本次工作以23个矿种圈定成矿靶区,重要矿产地、物化遥异常等信息,并在最新划分的90个三级成矿区带基础上,划分了26个全国固体矿产勘查重点成矿区带,并进一步优选10个重点部署区带。

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 90three-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.
