We discuss the alternative model of internal waves (instead of storminduced waves) as the hydrodynamic agent providing the highenergy events needed to explain the origin of the peloidal–intraclastic intermound facies and, likely, also the nutrients needed by the microbialites and siliceous sponges to grow.

Lower Triassic mixed carbonate and siliciclastic setting

The intraclastic limestone of Facies 4 lithologically resembles Facies 1b, the flat pebbles and cobbles in Facies may represent transgressive lag deposits, and its basal erosive surface 4 are more rounded and dolomite clasts are rare. Facies 4 overlies shal may therefore represent a major marine flooding surface. low marine deposits (e.g
