Fault gouge can range from sand rich to shale rich. [[:file:evaluating-top-and-fault-seal_fig10-21.png|Figure 2]] shows three fault zones exhibiting a spectrum of sand-shale ratios. The table below describes the position of the three faults, their sequences and characteristics, and their location. | Fault gouge can range from sand rich to shale rich.
