WebJun 1, 2015 · These cave levels formed during cold periods with stable river beds, and are coeval with fluvial terraces of rivers that flow perpendicular to the strike of bedding in gypsum monoclines. When rivers entrench, renewed cave formation occurs very rapidly, resulting in the formation of a lower level.
WebOne of the dominant karst-forming processes is the dissolution of soluble rock by the action of water, forming solution, or dissolution caves (White and Culver, 2000; Palmer, 2007 ); consequently, most caves are dissolutional in origin.
WebIn epigenic caves, where water flows underground from the surface, various types of sediment are deposited, including gravel, sand, clay and loam. The transport of these sediments can mechanically enlarge karst caves by scouring the walls and floors, and significantly transforming cave channels. ...
