| Punchbowl fault (near center of photo) juxtaposes sedimentary Punchbowl Fm (right) over igneous & metamorphic basement (left) |
Fault-related folding created a basin-wide syncline in the Punchbowl FM. Syncline is recognized in photo by further sedimentary beds dipping toward viewer, beds on right side of photo dipping left (SW), and nearest beds dipping away from viewer. Fold axis is parallel to length of picture (trends NE-SW) and plunges to the left (SW) |
