In the following discussion, 2-D cross sections demonstrate each of these parameters on theoretical gravity profiles. While the models may not be geologically reasonable, the concepts they demonstrate provide important building blocks for more complex geometric modeling, which is often performed to solve real exploration problems. When modeling gravity effects, it is much more important to constrain the size (shape) and depth of the geologic body than it is to constrain the density.
