HYPOGENE CAVE PATTERNS
Abstract:

The hypogenic cave pattern re?ects the speleogenetic processes incvolved. Processes vary according to the depth in the aquifer, involving mixing corrosion by convergent ?ux and with meteoric water, cooling, sulfur oxidation, carbon dioxide degassing, and condensation-corrosion. Cave patterns are: isolated geodes, 2D and 3D multistory systems following joints and bedding planes, Giant phreatic shaft, Water table mazes, Isolated chambers, Upwardly dendritic spheres, Water table cave, ‘Smoking’ shafts. The development of caves by hypogene processes (i.e. “hypogenic speleogenesis”) corresponds to the formation of caves by water that recharges the soluble formation from below, driven by hydrostatic pressure or other sources of energy, independent of recharge from the overlying or immediately adjacent surface” (FORD, 2006). Hypogenic caves - often referred to as “thermal caves” - were often considered as an “exotic” side of the “normal” (i.e. meteoric) caves. Palmer (1991) estimated that about 10% caves have hypogenic origin. Recent studies (overview in KLIMCHOUK, 2007) have emphasized the speci?c hydrogeological background and shown that hypogenic caves are much more common than previously thought. The extreme diversity of settings (carbonic, sulfuric, thermal, cold, deep phreatic, shallow phreatic, vadose...) in different geological or geomorphological contexts produces a puzzling impression: each hypogenic cave seems to be unique, with few characteristics in common with the other hypogenic caves in terms of their patterns.
