Schlern Formation

The Schlern Formation, also known as Schlern Dolomite, and Sciliar Formation or Sciliar Dolomite in Italy, is a limestone, marl and dolomite formation in the Southern Limestone Alps in Kärnten, Austria and South Tyrol, Italy.

Description
It preserves fossils dating back to the Middle Triassic period (late Anisian-middle Ladinian), or Illyrian to Longobardian in the regional stratigraphy. The formation correlates with the Wetterstein Formation of the Northern Limestone Alps. The formation is also coeval with the Livinallongo or Buchenstein Formation. The Schlern Formation is unconformably overlain by the Cassian Dolomite, and overlies the Contrin Formation separated by another unconformity. Deposition of the formation took place between the Pelsonian Humid Interval and the Ladinian Humid Interval, that preceded the better known Carnian Pluvial Event (CPE).

In Italy, the unit is recognized in the Civetta and Latemar reef buildups, and in Austria at the Gartnerkofel.
