Definition:
Karstification is the geologic process of differential chemical and mechanical
erosion by water on soluble bodies of rock, such as limestone, dolomite,
gypsum, or salt, at or near the Earth4s surface. Karstification is exhibited
best on thick, fractured, and pure limestones in a humid environment in which
the subsurface and surface are being modified simultaneously. The resulting
karst morphology usually characterized by dolines (sinkholes), hums (towers),
caves, and a complex subsurface.
