LSTRKFALTG - A forward modeling program to compute theoretical gravity anomalies of strike limited listric fault structures with prescribed vertical variation in density
A method to compute the gravity anomalies of strike limited listric fault structures among which density contrast varies continuously with depth is presented along with a program, LSTRKFALTG. expression for the gravity anomaly due to a listric fault structure having finite strike length is the space domain using both analytical and numerical approaches. The main program is supported a subroutine SIMP. Calculation of gravity anomalies at different offsets across a synthetic fault reveals the fact that the offset of the profile controls the magnitude of the gravity anomaly. input and output data files pertaining to a synthetic fault model are presented. The validity and of the method is demonstrated with a real field example. (C) 2010 Elsevier Ltd. All rights reserved.
