Boundary analysis using moving average differences of bouguer gravity anomalies

Boundary analyses are commonly used methods in gravity data processing in order to investigate possible source body boundaries from Bouguer gravity anomalies. Despite most of the methods use derivatives to estimate boundaries, it is possible to apply boundary analysis using simple arithmetic operations. In this study, we present Moving Average Differences as a new and simple boundary analysis method. The method examines the smoothed areas of Bouguer anomalies by moving average filter to enhance the boundaries. We tested this method on artificial and actual Bouguer gravity anomalies and compared with commonly used boundary analysis methods.
