... to replace sulfates with calcite and to form karst and small caves. All were later buried by ~2 km of Pennsylvanian–Cretaceous strata. Groundwater flow and speleogenesis in the Madison aquifer were renewed by erosional exposure during Laramide uplift. Post-Laramide speleogenesis enlarged paleokarst voids...

... We show the potential of paleomagnetism applied to sediments filling cave passages for chronology purposes, since the formation of caves cannot be directly dated. The Atapuerca karst system (N Spain) offers a suitable case scenario because it contains a multilevel karst system developed during...

... Weekly water samples collected in the spring and summer of 2012 demonstrate the dynamic geochemistry within the epikarst of an alpine karst aquifer in Timpanogos Cave National Monument in the Wasatch Mountains near Salt Lake City, Utah, USA. The results of chemical analysis of water from four...
