The Carnian stratigraphy of the Dogna area (Julian Alps, Northern Italy) has been investigated. Six lithostratigraphic units have been recognized between the Ladinian Sciliar (or Schlern) dolomite and the latest Carnian base of the Dolomia Principale. Facies analysis indicates that the Carnian succession of Dogna has been deposited in a shallow water, carbonate-siliciclastic ramp sedimentary environment. New biostratigraphic data (palynomorphs, and a few ammonoids) allow a correlation with the better known areas of Cave del Predil and Dolomites. This correlation framework highlights striking differences in the evolution of the Carnian carbonate platforms of the Southern Alps.

Abstract
The Carnian stratigraphy of the Dogna area (Julian Alps, Northern Italy) has been investigated. Six lithostratigraphic units have been recognized between the Ladinian Sciliar (or Schlern) dolomite and the latest Carnian base of the Dolomia Principale. Facies analysis indicates that the Carnian succession of Dogna has been deposited in a shallow water, carbonate-siliciclastic ramp sedimentary environment. New biostratigraphic data (palynomorphs, and a few ammonoids) allow a correlation with the better known areas of Cave del Predil and Dolomites. This correlation framework highlights striking differences in the evolution of the Carnian carbonate platforms of the Southern Alps.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
