By stereographic projection, using the attitudes determined in Problem 3.1, determine the amount (in degrees) and direction

Question:

By stereographic projection, using the attitudes determined in Problem 3.1, determine the amount (in degrees) and direction of Neogene tilting on the fault blocks of the Bree Creek Quadrangle that contain Tertiary rocks.Northeastern fault block Central fault block Western fault block Post-Rohan Tuff/pre-Helm's Deep Sandstone


Problem 3.1

On the Bree Creek Quadrangle map determine the exact strike and dip of the Miocene and Pliocene units and label the map accordingly with the appropriate symbol. List each attitude in the space below as well as on your map. Use the lower contact of each unit, because the upper contact may have been eroded.

After determining the strike and dip of each formation, try to visualize the geology in three dimensions. Make sure that the attitude you determined is in agreement with the outcrop pattern.
