| Direction and Significance of Iron Ore Mineralization Prediction Based on the Ore Deposit Metallogenic Series Theory |
| At present, the supply situation of iron ore resources in China is rigorous, thus, it is urgent to achieve a breakthrough in iron ore prospecting. The metallogenic series of ore deposits is the summary and refinement of the metallogenic law. It has been enriched and developed in the prospecting practice of multiple ore types and different geological units. Now it has become the basic theory guiding the geological exploration in China, and is of great significance for deepening the research on iron ore mineralization prediction and determining the direction of ore prospecting. There are 18 ore deposit metallogenic series dominated by iron ore deposits in China, and at least 67 types of mineral prediction types, forming a relatively perfect metallogenic system. According to the research results of China's iron ore deposit metallogenic series theory system, the prediction of iron ore mineralization should focus on: ① Metallogenic geological basis-identifying metallogenic elements; ② Extraction and analysis of characteristic mineralization indicators and prospecting indicators; ③ In-depth analysis and rule summary of new discoveries in ore prospecting; ④ Discrimination of new iron ore types and study of its metallogenic regularity; ⑤ A new understanding of the structure of key mines; ⑥ From the perspective of metallogenic system, the study of “whole-site mineralization” and “absence prospecting” should be carried out; ⑦ The construction of metallogenic lineage and explore the absent metallogeny (ore types, metallogeic types and ore-forming ages); ⑧ Ore prospecting and comprehensive utilization of iron ore resources based on the market and demand; ⑨ Rebalance of the relationship between resource development and environmental protection from the perspective of system theory. |
