Limestone areas
7 important questions on Limestone areas
What is the formula for karstification. You may split it up in the processes: dissolving CO2 gas, further split up of at increaging pH, dissolving chalk
Where's your favourite sort of tower karst and what's a geological description for this?
Where's your favourite cave system of karst?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Mention 4 different names for sinkholes related to dissolving limestone, of which 2 are related to the cause of sinking. How does this relate to GW?
- Cenote
- Solution sinkhole
- Cover collapse sinkhole
Groundwater development induced by karst: collapsed doline
Explain the 2 hydrogeological units on top of the Floridan aquifer system that is based on paleokarst carbonate bedrock (dolomite/limestone) and how this influences water flow through the aquifer system.
Name the 3 layers of the Floridan aquifer system that is based on paleokarst carbonate bedrock (dolomite/limestone).
In which layers in the Floridan aquifer system do sinkholes occur? Which two types can be distinguished and how do they differ?
Cover-collapse sinkhole: could breach the confining unit(clay) in the mantle/overburden (clay, sand), allowing water to flow into the Upper Floridan aquifer. Not sure why they collapse.
