ABSTRACT

Terracing (Cordell and McCafferty, 1989, Philips, 1992) is an operator that is applied to
potential field data to produce regions of constant field amplitude that are separated by
sharp boundaries. Magnetic data is usually transformed into pseudogravity data
(Baranov, 1957) prior to the application of terracing. The objective of terracing is ’to
recast potential field maps into a geologic map like format’ (Cordell and McCafferty,
1989). Terracing is performed by moving a window through the data and computing the
curvature at each point.
