Middle to Late Triassic sedimentary record in the Alpine realm is characterized by presence of various masses of dolomitic rock formations. In the Northern Calcareous Alps the dolomitic mass of Ladinian - Norian age is divided by the Carnian sandstones and shales of Lunz Formation to the Ladinian - Carnian Wetterstein Dolomite and Norian Main Dolomite. The Main Dolomite reaches higher thickness than underlying dolomites in Alps, therefore it is considered as more important "Main".
