Condensation water in heritage touristic caves: Isotopic and hydrochemical data and a new approach for its quantification through image analysis

Condensation water is a major factor in the conservation of heritage caves. It can cause dissolution rock substrate (and pigments art drawn on it) or covering thereof with mineral components, depending chemical saturation degree condensation water. In show caves, visitors act as source CO2 and thus modify microclimate, favouring negative processes that affect spite their interest, studies composition this type are scarce not very detailed. work we present research Nerja Cave, one main tourist caves Europe. The joint analysis isotopic, hydrochemical, mineralogical microbiological data use image have allowed us to advance knowledge risk for demonstrate usefulness quantify scope possible corrosion process could be producing bedrock, speleothem art. To our knowledge, application (relative caves) first has been documented.
