| The Research and Application of Explorational Technology of “Penetrating” to Geology and Mineral Investigation in Overburden Area |
| 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. |
