| Abstract: | Based on the analysis of geochemical characteristics and metallogenic physico-chemical conditions of ISL-amenable sandstone-type uranium deposits,the formation mechanism of self-potential field is discussed,a mathematic calculation model has been set up,and the simulation calculation has been performed for self-potential anomalies above uranium ore bodies of ordinary form,features of survey curve are analysed and methods for correcting topography at self-potential anomalies are discussed,and a simulation curve of self-potential in the area of slope topography has been presented.Finally,the availability of the method is demonstrated by an example. |
