Abstract��
The forward anomaly of regular geological bodies is the basis for the interpretation of actual data, so its correctness is crucial. Gradient step gravity anomaly forward formula listed in the existing textbooks and most of the papers have distortion points under certain conditions, which will cause trouble to the data interpretation of the structural model. Starting from the gravity integral expression of the step, the author re-derived the gravity anomaly forward formula of the inclined step model. The model test shows that the new derivation formula will not have distortion points, which provides more accurate basic data for data interpretation. |
