Time
Time is the final variable but it is an important variable. The time it takes to form the a karst landscape depends on the other four variables that we discussed.
Other variables include the Climate and potentially the Biology of the area.
Time in the Valley and Ridge:
- The rocks in the Great Valley are Cambrian to Ordovician in age so it has been 500 million years since those events have been deposited. More time= more time for diagenesis to take place.
- With development well below the water table shows evidence that the karst landscape is very mature (Doctor et al., 2008).
- The rock in the surrounding highlands are Mississippian age so it has been about 330 million years since those events have been deposited.
- Karst features in this rock are Telegenetic, meaning that they were formed from in the later stages of diagenesis.
- Lithology (Rock Type, Age, Weathering Properties of the Rock)
- Solvent (Aggressiveness of the water, discharge rate, carbonic acid or sulfuric acid)
- Gradient (The range of elevations in the area)
- Geometry (The structural influence of the area and how it influences the landscape)
