A Fast Method for Interpretation of Self-Potential Anomalies Due to Buried Bodies of Simple Geometry
Publikováno v:
Pure and Applied Geophysics. 178:3027-3038
The numerical method presented here is simple, fast and designed to determine automatically the depth, shape, polarization angle and electric dipole moment from residual self-potential (SP) anomalies due to ore bodies of simple geometry. The calculat

We present a least-squares minimization approach to estimate simultaneously the depth to and thickness of a buried 2D thick, vertically faulted slab from gravity data using the sample spacing – curves method or simply s-curves method. The method al

We have developed a simple method to determine completely the model parameters of a buried dipping fault from gravity data (depths to the centers of the upper and lower portions of the faulted thin slab, dip angle, and amplitude coefficient). The met

We have developed a simple and fast quantitative method for depth and shape determination from residual gravity anomalies due to simple geometrical bodies (semi-infinite vertical cylinder, horizontal cylinder, and sphere). The method is based on defi

In this paper, we develop a method to determine the depth to two superimposed sources from a self-potential anomaly profile. The method is based on finding a relationship between the depths to the two superimposed structures from a combination of obs

We have developed three different least-squares minimization approaches to determine, successively, the depth, dip angle, and amplitude coefficient related to the thickness and density contrast of a buried dipping fault from first moving average resi

We have developed a generalized minimization approach to depth and shape determination from potential field data (gravity, self-potential, or magnetic) due to sources of simple geometry (e.g., spheres, cylinders, dikes, contacts) that resemble minera
