The fault boundaries are indicated by thick black lines. 180Explanation / Answer
1. There is depositional conformity between Ridpath Sandstone and Kavalier Shale because there is continuous deposition near the boundaries and the boundary is smooth. The Stohr Fault has not caused displacement of strata.
2. The Gem fault is a dip-slip fault. This is beacuse displacement is along the dip of the fault plane
3. The Stohr fault is a normal fault. This is beacuse while the displacement is vertical, the hanging wall block has moved dowwnwards relative to the foot wall block.
4. The Gem fault is older than the Stohr Fault. This is beacuse the Stohr fault has npot caused any displacement of strata and has left the beds undisturbed. The Gem fault has caused disturbance in the beds.
