2SHH]8YXSVMEP1ERYEPStep 5The outcrop pattern of the unconformity is clear in parts of the magneticsimage, but is unclear in other areas, and is very hard to pick at all in the gravityimage. You can enhance the unconformity contact by performing a 1st verticalderivative calculation on the magnetics image. To do this select VerticalDerivatives->First>Magnetics from the Geophysics menu and selecting thefile name you have just saved, and then typing in a new file name for the 1 st VDimage.
