PDEPTH: Calculation of depth to magnetic basement from profile data.
PDEPTH is a program for automatic calculation of depth to magnetic basement based on a total magnetic field or anomaly profile, and PDEPTH forms an inte- grated part of the IMP system developed by T.H.Torsvik. PDEPTH utilizes Phillips method (1975,1978,1979) for calculating magnetic basement depths and is adapted from an original mainframe Fortran program written by Phillips (ADEPTH). Conversely, PDEPTH is written for IBM compatible computers. A program named IMDEPTH is also available; this program however handles grid-data for automatic scanning and calculation of magnetic basement depths. This report describes how to use PDEPTH and outlines the basic software theory.
