GM3D has been developed for computering the gravity or magnetic anomaly due to a three-dimensional body, and for plotting the resulting contour map. A complex body may be constructed from several right-rectilinear vertical-sided prisms. The program allows the input and editing of the prism data which are then used to calculate the anomaly map for plotting. Plotting is done on either a Tekronix 4014 graphics terminal, a Statos electrostatic plotter, or a CalComp pen plotter. A terminal plot is also available which can be printed on any terminal and on a line printer. The program is written in FORTRAN IV code and operates on a PRIME 400 computer system. Adaptation of the program to other systems is relatively straightforward.
