The landscape of the Dolomites is dominated by Triassic carbonates, deposited from the Anisian to the Carnian.
In the Lower Carnian (Julian) the percentages of carbonates increments due to the diminishing eustatic sea-level change.
The last part of the reefal evolution is the development of patch reefs constituted by colonial corals (Scleractinia).

Large areas of the reefs of the Dolomites suffered karstic erosian due to sea regression in the Anisian.
A new transgression in the Carnian permitted new carbonate platforms to develop in swallow basins.
