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.
