1. When this rock formation was deposited the sea level in this area was rising; or going through a
marine transgression.
2. Mica Sandstone was Deposited Horizontally – there was a bidirectional flow with relatively calm
moving water causing symmetrical ripples
3. In areas where the mica sandstone is present, crinoids, brachiopods can be found.
4. Shale rock unit was deposited horizontally – trilobites can be found
5. Limestone Rock Unit deposited horizontally – Rugose coral found
6. Ductile deformation due to compressional forces cause the beds in the rock units causing the
entire rock unit to fold
7. Dip of west and east
8. This resulted in a non-plunging, asymmetrical syncline.
9. Many years passed eroding the beds in the Early Paleozoic and the Mesozoic Cenozoic portion
of the area compared to when the next rock unit was laid down. – creating an angular
unconformity underneath the newly deposited beds
10. Some unidirectional body of water entered the area depositing the quartz sandstone to be
horizontally. This area contains asymmetrical ripples showing that the flow was unidirectional
with a transitional flow speeds moving from 2D crests to 3D crests. Tuning fork junctions were
present to prove this.
a. Echinoderms and Clams present (Meso/Ceno)
11. A body of water deposited Glauchonite rock unit was deposited horizontally
a. Fish Poo gives it the green color proving that there were fish present at the time of
deposition
12. A body of water deposited Iron Sandstone Deposited horizontally
a. Vertebrae fossils were found
13. You could tell the area was evolving due to the evolution of the animals in the rock unit
succession. Along with the animals evolving the rock units changed due to organisms new affect
on them.
14. Due to brittle deformation of the area and extensional force the area experienced a normal fault
where the hanging wall moved downward
15. We can tell this because of the way the beds show up in the formation of the rock unit
16. Eroded to present day surface
