Résumé

On a trouvé dans la grotte-perte Ponikva, en Odolina (Slovénie), les restes d'une inscription murale datant d'août 1929. La peinture employée sur le mur a protégé la roche contre la corrosion; c'est pourquoi à cet endroit la surface de la roche est convexe, en relief. En fonction de l'âge de l'inscription et de la convexité mesurée des lettres, on suppose que la vitesse de corrosion est de 1,05 à 1,98 mm par siècle.

Abstract

The inscriptions on cave walls are usually treated for preservation, because of their historical value. In the Ponikva cave, in Odolina, the old signatures were made of oil paint on the scalloped wall and thus the paint protected the rock surface against corrosion; that is why this rock surface juts out. The corrosion rate of the unprotected rock was measured by microerosion meter and this corrosion activity could then be compared respectively with laboratory tests and with similar activity in other caves.
