Karst

Karst is a geological formation shaped by the dissolution of carbonate rock, such as limestone or dolomite. It has also been documented for weathering resistant rocks, such as quartzite. The primary driver of karst is due to mildly acidic water, such as rainwater, acting on weakly soluble carbonate rock. Persistent exposure to the acidic water will begin to dissolve away the carbonate rock and form jagged features or potholes. Over time these features become significantly larger. Karst features can also develop underground on buried carbonate rock, forming massive caves and cavern systems.
