Partnach Formation
Geological formation in Austria
From Wikipedia, the free encyclopedia
The Partnach Formation is a Middle Triassic geologic formation in the eastern Northern Limestone Alps and Western Carpathians, within Austria and Slovakia, Central Europe.[1] The formation consists of alternating grey and green marls and shales (Partnach shales) and grey limestones (Partnach Limestone), often brecciated, oncolithic and containing clay intraclasts.[2] The formation is gradually evolving from the Reifling Formation. It is usually overlain by the Lunz/Reibl Formation or Wetterstein Formation. Sediments of the Partnach Formation were deposited in intrashelf basins.
