The following questions should help you begin to think about interpretation of 2D blocky models produced by forward modelling of gravity profiles. Models are provided below the questions.
1. If the host rocks are 2.67g/cc, what is the true density of the material shown with a density contrast of +0.13g/cc?
2. If the heavier zone consisted of material that was in fact more dense than shown here, would that zone have to be ...
3. What do you expect is the geologic material labelled with a density contrast of -0.37?
