A borehole with continuous core-sampling has been carried out in the south eastern side of the fossiliferous olistolith of the Eocene Pesciara di Bolca (Lessini Mountains of Verona Province, Italy), reaching 40 m depth. The borehole encountered more than 30 m of limestone, marl and clay, overlaying the volcaniclastic rocks. The sedimentary succession recovered, much thicker than the Pesciara outcrop, contains three main intervals of fossiliferous laminites (with fish, plants and amber), interbedded with calcarenitic and calciruditic beds rich in alveolinids and bivalves. The integration of geoelectric, sedimentological and stratigraphical data allow us to affirm that the site is still potentially exploitable for future paleontological excavations.

Abstract
A borehole with continuous core-sampling has been carried out in the south eastern side of the fossiliferous olistolith of the Eocene Pesciara di Bolca (Lessini Mountains of Verona Province, Italy), reaching 40 m depth. The borehole encountered more than 30 m of limestone, marl and clay, overlaying the volcaniclastic rocks. The sedimentary succession recovered, much thicker than the Pesciara outcrop, contains three main intervals of fossiliferous laminites (with fish, plants and amber), interbedded with calcarenitic and calciruditic beds rich in alveolinids and bivalves. The integration of geoelectric, sedimentological and stratigraphical data allow us to affirm that the site is still potentially exploitable for future paleontological excavations.Pubblicazioni consigliate
