Here is an example where the reflection geometries are fairly diagnostic
We have oblique progradation indicated by the seismic reflection geometries
This is very similar to the cartoon example covered in lecture 10b
We can predict where we would find coastal plain, shoreface and offshore deposits
We can then infer that there is a good possibility that we have a sand fairway in the region of nearshore deposits (yellow)
