MONTE GUGLIELMO LIMESTONE: A MIDDLE - LATE ANISIAN CARBONATE PLATFORM IN CENTRAL SOUTHERN ALPS (ITALY) IL CALCARE DI MONTE GUGLIELMO: UNA PIATTAFORMA CARBONATICA DI ETÀ ANISICO MEDIO-SUPERIORE NEL SETTORE CENTRALE DELLE ALPI MERIDIONALI

The Monte Guglielmo Limestone forms the uppermost part of the Monte Guglielmo ridge, in Eastern Lombardy (Northern Italy). While included in the basinal Angolo Limestone by the present official geological map at the scale 1:100.000, the Monte Guglielmo Limestone is indeed made up of shoaling algal banks, with interspersed lime mud. Most common facies are massive to dmbedded, locally dolomitized, boundstones and skeletal and intraclastic packstones and wackestones. Associated fossil fauna and flora include algae (blue-green algae and Dasycladaceans), benthic Foraminifera, gastropods, bivalves and echinoderms. Biostratigraphic analysis based on benthic Foraminifera allows a Middle - Late Anisian age (Pilammina densa zone).
