| 中文摘要:覆盖区矿产勘探和研究程度较低, 找矿难度大, 但矿产资源潜力巨大。在覆盖区一系列大型-超大型隐伏矿的发现中, “穿透性”探测技术起到了重要作用。本文在梳理国内外覆盖区基础地质矿产调查和“穿透性”探测技术应用现状的基础上, 关注成矿带覆盖区地质矿产调查中常用的地球物理(重磁电)探测技术, 深入分析了地球物理异常多解性的物性变化和地质因素问题。通过总结地质体解译中的常见问题及应对措施, 对开展覆盖区地质矿产调查进行了深入思考, 认为充分利用地物化综合信息, 探索和发展多尺度、多参数、多方法相互约束的综合探测解译技术是覆盖区“穿透性”探测技术的发展趋势。 |

| Abstract:Although it is difficult to conduct mineral research and exploration in overburden area, the resources of minerals there have great potential. In the discovery of a series of large-super-large concealed deposits in the overburden area, “penetrating” exploration technology has played an important role. On the basis of reviewing the present situation of basic geological and mineral investigation and “penetrating” exploration technology in the overburden area around the world, this paper pays attention to the geophysical (gravity, magnetic and electromagnetic) exploration technology commonly used in the geological and mineral investigation in the over burden area of the metallogenic belt, and deeply analyzes the physical changes of geophysical anomaly and geological factors. By summarizing the common problems and countermeasures in geological interpretation, this paper makes a thorough reflection on the geological and mineral investigation in the overburden area. It is considered that exploring and developing the comprehensive exploration and interpretation technology with multi-scale, multi-parameter and multi-method constraints is the development trend of the “penetration” exploration technology in the overburden area by making full use of the comprehensive geophysical and geochemical information. |
