Inactive stalagmites from the Silberen cave system and its surroundings (Muota Valley, Central Switzerland) have been dated by the 230Th/U method (alpha spectrometry and TIMS). The following complementary dating methods were applied : 234U/238U, paleomagnetism, palynology and electron spin resonance. Discussion of the results. The uplift rate of the mountains, the corrosion rate of the karstified surface and the incision of the valley bottom, suggest that karstification started 4 to 3 Ma (Middle to Upper Pliocene). The dated speleothems are therefore substantially younger than the beginning of speleogenesis
