| 摘 要： | 重力场概率成像方法对复杂地质体的成像效果较差，提出一种较好的适用于脉状矿体模型的改进方法．把重力异常场看作位于脉状矿体顶点的点源产生的场，从而把对脉状矿体的成像转换成对脉状矿体的顶点成像，并根据顶点推断脉状矿体的几何参数．脉状矿体的正反演结果表明。这种方法是可行的．

| Abstract: | Probability tomography can not inverse complex geologic body with high resolution in gravity field.For this reason,a new improved method which is good for vein model was brought forward.According to this method,the retrieved picture was regarded as distributing of point sources rather than vein body itself.Because gravity anomaly field is supposed to be generated by the point sources located vein body' points,geometry parameters can been deduced.Comparison of forward and inversion of vein bodies showed this method is practicable. |
