That covered karst is 1. a fossil or currently developing karst in karst limestone which underlies superficial deposits or other rock, and which may produce landforms at the surface which reflect subsurface karstification [19]; contrasted with naked karst, which is soil free. see also buried karst; interstratal karst; mantled karst; subsoil karst; sulfate-reduction karst. 2. a generally subdued karst landscape developed where carbonate rocks are affected by dissolutional processes beneath a soil cover (see bare karst) [9]. synonyms: (french.) karst couvert; (german.) bedeckter karst; (greek.) kekalymenon karst; (italian.) carso coperto; (russian.) pokryty karst; (spanish.) karst cubierto; (turkish.) ortulu karst; (yugoslavian.) pokriveni krs, pokriti kras.?

Hypogene speleogenesis and karst hydrogeology of artesian basins, 2009, p. 45-49

Haloes of altered oxygen isotope values ranging in size from < 1 m to several km have been reported around hydrothermal ore deposits. We have found that similar alteration zones could be induced by lukewarm to thermal cave-forming waters. A paleo wall in Entrische Kirche cave (Gastein Valley, Austrian Alps) preserved a 5 cm-thick brownish zone behind a thick flowstone. Across this zone the O isotope values gradually increase by 11 ‰, until they reach values characteristic of the unaltered marble. The isotope composition in the alteration zone is very different from that of the ?owstone above but is similar to phreatic calcite spar from hypogene (thermal) karst cavities in surface outcrops in the area. We interpret this isotopic pro?le as re?ection of the water-rock interaction in a low-temperature hydrothermal karst system. Similar alteration pro?les were found around solutional cavities at Hllenstein (Tux Valley, Austrian Alps), lined with hydrothermal calcite. Sigmoid shapes of isotope profiles suggest that the most-altered bedrock was isotopically equilibrated with paleo waters. This allows use of isotope mass-balance calculations to assess the temperature of the paleo waters. Isotope profiles acquired from a number of other hypogene caves in Austria failed to show any isotopic signals of bedrock alteration.
