中文摘要:当前, 我国铁矿资源供应形势十分严峻, 实现铁矿找矿突破迫在眉睫。矿床成矿系列是对成矿规律的总结和凝练, 在多矿种和不同地质单元的找矿实践中丰富和发展, 现在已经成为指导我国地质勘查工作的基础理论, 对于深化铁矿成矿预测研究、明确找矿方向有重要意义。目前全国已划分的以铁矿为主的矿床成矿系列有18个, 矿产预测类型至少67种, 构筑了相对完善的成矿体系。根据矿床成矿系列理论体系对我国铁矿的研究成果, 铁矿成矿预测应聚焦于: ①成矿地质基础-识别成矿要素; ②特征性矿化指示和找矿标志的提取分析; ③找矿新发现的深入剖析和规律总结; ④新铁矿类型的辨别及其成矿规律研究; ⑤重点矿山的构造重新认识; ⑥以成矿体系的角度开展“全位成矿”和“缺位找矿”研究; ⑦成矿谱系的构建和成矿缺位(矿种、类型、时代)的研判; ⑧以市场和需求为导向开展铁矿资源预测和综合利用; ⑨从系统论的角度重新平衡资源开发与环境保护的关系。 |

Direction and Significance of Iron Ore Mineralization Prediction Based on the Ore Deposit Metallogenic Series Theory |

Abstract: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. |
