Abstract

During an annual cycle the affect of microclimatic changes (of natural and anthropogenic origin) on the geochemical characteristics of seepage water and mineral precipitation rates was analyzed for 2 karstic caves which contrast in environmental stability and energy exchange with exterior. Castañar cave (Caceres, Spain) is an extremely controlled cave with limited visitation. Canelobre cave (Alicante, Spain) is a widely visited cave where the anthropogenic impact generates rapid and high-energy environmental changes. The obtained results reinforce the significance of the microclimatic fluctuations on short time scales in the dynamics of the subterranean karst systems, in terms of rates of mineral precipitation and growth of speleothems, as well as their key role for cave conservation
