Sedimentological and paleontological studies carried out on the Upper Triassic Dolomia Principale and on the Lower Liassic Calcare Massiccio carbonate platform successions of the Gran Sasso area (Central Apennine, Italy) allowed to recognize several microfacies types arranged in three different types of high frequency cycles, subtidal, peritidal and diagenetic. The cycles can be attributed to high frequency sea-level oscillations on a fifth and fourth order scale. Five algal assemblages have been identified: 1. Gyroporella vesiculifera, 2. Griphoporella curvata, 3. Palaeodasycladus spp., 4. Palaeodasycladus and Thaumatoporella, and 5.

E’stata condotta un analisi sedimentologica e micropaleontological sulle successioni di piattaforma carbonatica della Dolomia Principale (Trias superiore) e del Calcare Massiccio (Lias inferiore) dell’ area del Gran Sasso (Appennino centrale, Italia), al fine di precisarne l’assetto stratigrafico, il contenuto algale, la distribuzione delle facies e dei paleoambienti.
