Abstract

This paper deals with the evolution of the karst developed in the evaporite succession around Monferrato. In this area the thickness of the evaporite sequence is highly variable due to an important erosion surface formed at the end of the evaporite cycle and carved in the gypsum beds. Epigenic caves probably formed during this short intra-Messinian phase of emersion. Cave sediments contain benthonic and planctonic formaminiferal associations ranging in age from Burdigalian to Upper Pliocene. The formation of the most important caves of this area probably started at the end of the Messinian under epigenic conditions. Possibly, those inherited caves enlarged slowly during the Quaternary in an intrastratal and confined hypogene karst system
