Abstract:In order to make a new breakthrough in the prospecting of the coverage area, a suitable inherited fracture-controlling model for Tan-Lu fault system and a comprehensive prospecting model for the coverage area were established. Then an experimental method for identifying thin conductors in the coverage area was carried out to study Wuhe integrated exploration area mineralization and ore-controlling regularity. The results show that the NNE-NE fault is the main ore-controlling structure of Wuhe integrated exploration area. The spatial distribution pattern of the ore body has a good correspondence with the magnetic anomaly pattern. Combined with the ‘repeated circulation of one selection, three confirmation, four stages’ comprehensive prospecting model, the low-frequency electrical magnetic exploration method, the ground-well charging method and the positive and negative potential method in the coverage area, better prospecting results were achieved in this area. The magnetic anomaly step belt is used to find the secondary fault of Tan-Lu fault zone, which is also the ore-controlling fault. These three prospecting methods mentioned above can be used accurately to locate the ore body, and finally two gold polymetallic mineral deposits were found in Wuhe integrated exploration area. It indicates that these ore-controlling, comprehensive prospecting models and new prospecting methods have some guiding significance on prospecting in Tan-Lu fault system and the coverage area.
