Grünbach Formation
From Wikipedia, the free encyclopedia
The Grünbach Formation is an Austrian geological formation that dates to the early Campanian age of the Late Cretaceous. it forms part of the Gosau Group, and represents a marine regression event, representing a coastal/brackish environment, being underlain by the marine carbonate Maiersdorf Formation and overlain by the deep marine siliciclastic Piesting Formation. The main lithology is clay, marl, siltstone and sandstone, with a minor conglomerate component. Coal seams have also been noted.[1][2] It is notable for its fossils including those of dinosaurs and plants.
