Dear Mark,
GM-SYS® is a program for calculating the gravity and magnetic response from
a geologic model.
GM-SYS provides an easy-to-use interface for interactively creating and
manipulating models to
fit observed gravity and/or magnetic data. Rapid calculation of the gravity
and magnetic response from
2-D or optional 2¾-D model speeds the interpretation process and allows you
to quickly test alternative
solutions. Calculated responses change instantaneously as you change the
model. Models and data can
be imported from ASCII files, by hand, or extracted interactively from an
OASIS montajT database.

Subject: gravity and magnetics software?
> Can anyone out there point me toward some software that can do
> relatively simple gravity or magnetic profile calculations and models?
> For example, I'd like to be able to calculate a gravity profile above a
> cross section in which I know the density and distribution of rocks in
> the subsurface. The software can be Windows or Mac, shareware, freeware
> or commercial.
>
> Thanks in advance for any help you can provide.
