Abstract We have developed a scheme for the interpretation of gravity data by a two-sided fault-like geological structure. The scheme is based on the particle swarm optimization and determines the model parameters of the upthrown and downthrown of the fault. It uses the second horizontal derivatives, which are calculated numerically from the measured gravity data by applying some filters of consecutive graticule spacings (the so-called here window lengths or s-values). The developed scheme has been verified on various noise-free synthetic models. Following that, the accuracy of the scheme has been assessed on a number of noisy synthetic examples. Finally, the developed technique has been successfully applied to two real data examples from India and the United States of America. It is found that the model parameters obtained from the scheme developed here are in good agreement with those reported in the published literature.

使用全局粒子群技术通过两侧断层状地质结构解释重力数据

摘要 我们开发了一种利用两侧断层状地质构造解释重力数据的方案。该方案基于粒子群优化，确定断层上抛和下抛的模型参数。它使用二阶水平导数，这些导数是通过应用一些连续经纬网间距（这里所谓的窗口长度或 s 值）的过滤器从测量的重力数据中数值计算出来的。所开发的方案已在各种无噪声合成模型上得到验证。之后，该方案的准确性已经在许多嘈杂的合成示例上进行了评估。最后，所开发的技术已成功应用于来自印度和美国的两个真实数据示例。
