Abstract

A novel method based on Walsh function theory is developed for rapid computation of gravity anomaly over symmetric sedimentary basin. For the computation the initial model assumes that depth of symmetric basin vary exponentially toward the center along the profile. Walsh integral transform is used to construct the layered basin boundary structures using the exponential relation of the form of h=ex where h and x denote the depth and length of profile respectively. The binary waveform like Walsh function renders a more appropriate and natural representation of step-wise faulted sedimentary configuration. This procedure also facilitates fast convergence of the theoretically computed and observed gravity anomaly. The practical utility of the proposed method is demonstrated on synthetic gravity data as well as on field data obtained from East Slovakian Outer Carpathians sedimentary basin.
