Print this pageAbstract: Triassic Sequence Stratigraphy: Stratal Patterns and Ammonite Data. Examples from the Southern Alps (Northern Italy)
Vittorio De Zanche, Gianolla Piero, Mietto Paolo
The Triassic succession in the Southern Alps is made up of continental deposits, carbonate platforms and basinal mixed sediments variously stacked and interfingered.
The good seismic-like exposure, which allows a clear definition of stratal patterns, the great quantity of ammonites and the disposal of a highly resolved ammonite standard scale for the Anisian-lower Carnian interval, have permitted the sequence stratigraphic interpretation of the Triassic in the Southern Alps.
The sequence stratigraphic interpretation has allowed a reliable scheme of correlations between shelf, basin and continental deposits.
Third-order sequence boundaries and maximum flooding surfaces in different environments, as well as second-order peak transgressions and maximum regressions, are shown in connection with the ammonite data which allow the biochronostratigraphic calibration.
