Abstract The contact zone of Lianshanguan rock body is an important ore-controlling structural zone in the Lianshanguan-Qijiabaozi area. In order to detect the strike and the downward extension of the rock body contact zone and the distribution of radon concentration anomalies in the study area with the purpose of guiding uranium exploration in this area, the authors employed both audiomagnetotellurics and soil radon survey on the basis of the physical-chemical environment. Based on the comprehensive geophysical results, the authors determined the strike and the deep extension of the contact zone and delineated four uranium favorable zones, which provides the information in the depth for uranium exploration. Drilling verification shows that there are two uranium anomalous holes and one mineralized hole in No. Ⅳ section, thus achieving favorable application result.
