Raibl layers


Raibl layers

In the Upper Triassic, about 220 million years ago, the Raibl strata were formed in shallow seas with numerous reefs. A dry and subtropical-hot climate prevailed. The input of sand and mud by rivers resulted in the death of the reefs. Today these deposits can still be found in the clay and sandstones of the Raibl strata.

Under the term Raibler Schichten, however, other stones can be found. Besides Rauhwacke and limestones, one can also find gypsum and dolomite. These stones were formed in bays, which were separated from the sea. There, the evaporation of the sea water caused the precipitation of gypsum crystals from the brine.

The Raibl strata do not form jagged peaks. The weathering of the soft, clay-rich and gypsum-bearing strata sequences creates good soil and forms lush alpine meadows. This source rock, which is well suited for soil formation, also forms valleys, embrasures and hollows.
