The evolution of karst and caves in the Konûprusy region Bohemian Karst, Czech Republic), Part II: Hydrothermal paleokarst, 1998, Bosak, Pavel

The origin of hydrothermal karst cavities was connected with the Variscan hydrothermal process. The cavities were formed and filled by crystalline calcite. The process was accompanied by the intensive dolomitisation. Younger phase of hydrothermal karstification was not connected with vein-filling, but with the deep circulation of groundwater, probably associated with neovolcanic activity in the Bohemian Massif. This is supported by pollen grains and decomposed volcanic ash in speleothems which were formed after the major phases of speleogenesis. It is supposed that caves in the Konûprusy Devonian were formed in confined aquifer under phreatic and batyphreatic conditions. Thermal conditions appeared when paleogeothermic gradient was increased due to intensive neovolcanic activity. Hydrothermal karstification partly changed the morphology of caves. The maximum temperatures were stated to 60-700 C from large calcite crystals precipitated under phreatic and deeply phreatic conditions. The piezometric level was situated above limestones in Upper Cretaceous platform siliciclastics as indicated by numerous subvertical phreatic tubes („depressions") filled with sunkened Cretaceous and Tertiary sediments after the water buyoancy support decreased. Popcorn-like silicified Konûprusy Rosettes can be result of decrease of thermal water level and mixing with infiltrating meteoric waters. Outer zones of large calcite crystals with precipitation temperatures of about 400 C can indicate the gradual cooling of the whole system.


Traage entre le lac de barrage de Salanfe et les sources thermales de Val dIlliez (Valais, Suisse) : tectonique, lithologie et gothermie, 2003, Sesiano, Jean
Dye tracing between the lake of Salanfe and thermal springs of Val dIlliez (Wallis, Switzerland): tectonics, lithology and geothermics - A detailed fieldwork has allowed us to locate a sinkhole where some water from the artificial lake of Salanfe disappears. Two dye tracing experiments have proved the link with hot springs in Val dIlliez, 9 km to the NW. The temperature increase is due to the depth the water reaches before coming up, following an alpine inverse fault.

Temperature distribution in karst systems: the role of air and water fluxes, 2004, Luetscher M. , Jeannin P. Y.

A better understanding of heat fluxes and temperature distribution in continental rocks is of great importance for many engineering aspects (tunnelling, mining, geothermal research,…). This paper aims at providing a conceptual model of temperature distribution in karst environments which display thermal “anomalies” when compared to other rocks.
In temperate regions, water circulations are usually high enough to completely “drain out” the geothermal heat flux at the bottom of karst systems (phreatic zone). A theoretical approach based on temperature measurements carried out in deep caves and boreholes demonstrates however that air circulations can largely dominate water infiltrations in the karst vadose zone, which can be as thick as 2000 m. Consequently, temperature gradients within this zone are similar to the lapse rate of humid air (~0.5°C/100 m). Yet, this value depends on the regional climatic context and might present some significant variations.
