Abstract

We present a new semi-automatic gravity method for<br>estimating a complex interface separating two media<br>predominantly homogeneous having, however, multiple<br>interfering sources in one or both media. The method<br>combines a robust fitting procedure and the constraint<br>that the interface is very smooth close to the interfering<br>sources. The proposed method differs from the regionalresidual<br>techniques by using no signal spectral content<br>assumption about the interface to be estimated, i.e., the<br>interface can be characterized by both low- and highfrequencies<br>features. As a result, it may be applied to a<br>complex geological setting where the interface is complex<br>and the interfering bodies are either shallow- or deepseated<br>sources. The proposed method was tested on<br>synthetic and real gravity data, producing good results.
