针对隐伏矿床和新类型矿床,科学选靶是矿产勘查成功的关键.根据地质异常致矿理论,将地壳结构复杂的地质异常区域定义为找矿有利地段;在找矿有利地段内,根据成矿系统理论,将成矿关键要素(源、运、储、盖)发育的地段定义为找矿潜在地段;在找矿潜在地段内,根据成矿系列理论,将可能出现矿床共生组合的地段定义为找矿远景地段.研究表明:(1)矿产资源体等级性和不均一分布,矿集区内,矿床规模-频率幂律分布和大型矿床通常在找矿初期发现的规律奠定了多尺度聚焦找矿战略的理论基础;(2)地质矿化单一信息的多解性和不确定性奠定了应用综合致矿信息找矿战略的理论基础;(3)基于成矿系统模式的概率模拟和基于综合找矿模型的概率模拟是从成矿的本质和现象两个方面评价可能矿化地段的最有效途径.
According to the theory of geology anomaly, the geological anomalous area with complex crustal structure is defined as the favorable prospecting area. In the favorable prospecting area, according to the mineralization System theory, the development of the key elements of mineralization (source, transport, reservoir, cover) is defined as potential prospecting areas; prospecting potential areas, according to the theory of metallogenic series, the symbiosis of the deposit may be defined as the location to find The results show that: (1) The hierarchical and uneven distribution of mineral resources, the distribution of power-law and the scale-frequency power law in the ore-collecting area and the law of large deposits usually found in the early stage of prospecting have laid the foundation for multi-scale focusing prospecting (2) The multi-solution and uncertainty of single information of geological mineralization laid the theoretical foundation for the prospecting strategy of integrated ore-producing information; (3) Based on probabilistic simulation of metallogenic system model and The probabilistic simulation of the mine model is the most effective way to evaluate the probable mineralized section from two aspects of the nature and phenomenon of mineralization.
