Resumen
Geochemical characteristics of karstic water in Tito Bustil/o Cave are the result of two main types of recharge: authigenic recharge via percolating and infi/trating water through conduits and fractu­res, and allogenic-authigenic recharge vía San Miguel river that sinks (Gorgocera ponor) into the karst system. The chemical composition of San Miguel river reflects that its drainage basin is loca­ted both on siliceous (shale and sandstones) and calcareous lithologies; likewise, the influence of tides is a/so present. By means of geochemistry modelling it has been proven that water chemical composition in the area of Tito Bustillo cave reflect a double influence: (1) 60% of discharge of groundwater by mean of springs and (2) 40% of water coming from the headstream.
