【摘要】 通过对可地浸砂岩型铀矿的地球化学特征及成矿物理化学条件分析,详细讨论了其自然电场的形成机理,建立了数学计算模型,并对常见形态矿体的自然电位异常进行了模拟计算,分析了曲线特征,讨论了自然电位异常地形校正方法,并给出了一种斜坡地形条件下的自然电位模拟曲线。最后,以一个实例说明该方法的有效性。更多还原

【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.更多还原
