•: Cave ferromanganese stromatolites and associated wall notches mark paleo-watertables.
•: Paleomagnetism of cave Fe–Mn deposits: a new approach to date paleo-watertables
•: Acidity produced by watertable Mn–Fe oxidation contributes to speleogenesis.
•: Allogenic-sediment input controls watertable versus phreatic passage development.
•: Matrix porosity in host dolostone induces spongework cave-wall mesomorphologies.
