What is it about?
Euler deconvolution is often erroneously applied to locate and estimate the depth to the top of a fault, using gravity data. This paper shows how it should be done. Its not straightforward.

Why is it important?
It illustrates the proper approach to using Euler deconvolution applied to gravity data. The technique is widely misused in this context
Perspectives
Simple Euler deconvolution (such as is available commercially) assumes that all anomalous structures are "single point" sources, that is, ones which display a single critical location in profile. The is, one of: sphere, line source, sheet edge source or infinite contact (mag only). Simple deconvolution SHOULD NOT be applied to a fault of finite throw, which has two such critical points (top and bottom). Euler's differential equation is non-linear for this case and simple software is inapplicable (and, if applied, misleading).
