Origin of Limestone Caves | The Institute for Creation ...

Although solution was a major process in the formation of limestone caves, some major problems are encountered if these caves are considered to have formed only by solution. The first problem is the origin of the original fracture porosity along which circulation of acidic groundwater could be initiated.
