Non-Carbonate Karst Landscapes

"Karst" is a land system that has been shaped, at least largely, by chemical solution. The vast majority of such landscapes worldwide were formed in limestone or other carbonate rocks. "It is now widely recognised that both quartz and amorphous silica are soluble in water, particularly at high temperatures. However, solution is much slower than in many other rocks such as the carbonates, gypsum and salt" (AB – IUCN). This phenomenon has only been identified by geo-morphologists since c1966.
