    Sinkholes are far less common in areas where limestone is covered with an overlying surface layer of insoluble rock such sandstone or shale. The caves that form in the underlying limestone are, in this situation, protected from collapse by the overlying insoluble surface layer. Very large caves can form under these conditions.

    Some rocks, such as granite, do not change much at the lower metamorphic grades because their minerals are still stable up to several hundred degrees. Sandstone and limestone don't change much either because their metamorphic forms (quartzite and marble, respectively) have the same mineral composition, but reformed larger crystals.
