The Liard Formation is a stratigraphic unit of Middle Triassic to Late Triassic age in the Western Canadian Sedimentary Basin that is present in northeastern British Columbia. It takes its name from the Liard River, and was first described from outcrops on the southern bank of that river, near Hell Gate Rapids in the Grand Canyon of the Liard, by E.D. Kindle in 1946.
The Shadow Lake formation is a geological unit that crops out in Southern Ontario, Canada and northern Pennsylvania, United States. The shaly sections act as a caprock to petroleum reservoirs.
San Cassiano Formation (Anisian-Carnian) is a geologic formation located on the Southern Alps in the Dolomites. These Triassic dolomites are considered to be a classic example of ancient carbonate platforms. As the allochthonous elements in the Shale strata show a good preservation, fossils and microbialites contained in these elements are useful in detailed geochemical analyses.
The Cairn Formation is a geologic formation of Late Devonian (Frasnian) age in the Western Canada Sedimentary Basin. It was named for the Cairn River near its junction with the Southesk River in Jasper National Park by D.J. McLaren in 1955.
The Southesk Formation is a stratigraphic unit of Late Devonian age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains and foothills of Alberta and southeastern British Columbia. It was named for the Southesk River in Jasper National Park by D.J. McLaren in 1955.
The Beaverfoot Formation is a stratigraphic unit of Late Ordovician to Early Silurian (Llandovery) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains of British Columbia and Alberta, and the Purcell Mountains of British Columbia. It consists of carbonate rocks, and was named for the Beaverfoot Range at Pedley Pass southeast of Golden, British Columbia by L.D. Burling in 1922.
The Fairholme Group is a stratigraphic unit of Late Devonian (Frasnian) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains and foothills of Alberta and British Columbia. It was named for the Fairholme Range near Exshaw in the Canadian Rockies by H.H. Beach in 1943.
The Sierra Madre Formation is a geologic formation in Chiapas state, southern Mexico. It consists of marine dolomites and limestones. The formation dates to the Middle Cretaceous, spanning from the Aptian of the Early to the Cenomanian of the Late Cretaceous.
The Baitoa Formation is a geologic formation in Dominican Republic. The formation consists of siltstones and limestones deposited in a shallow marine to reef environment. The formation, unconformably overlying the Tabera Formation and unconformably overlain by the Cercado Formation, preserves bivalve, gastropod, echinoid and coral fossils dating back to the Burdigalian to Langhian period.
The Ramsau Dolomite is a dolomitic geologic formation in the Northern Limestone Alps, in Bavaria, Germany. It is a unit of the Wetterstein Limestone found in the Limestone Alps. It preserves fossils dating back to the Carnian stage of the Triassic period.
The Kössen Formation is a Late Triassic (Rhaetian-age) geological formation in the Northern Calcareous Alps of Austria and Germany, in the Tiroler-Lech Nature Park. During the Late Triassic, the area now occupied by the Northern Calcareous Alps was instead a long, passive coastline at the western tip of the Neotethys Ocean. The environment was initially dominated by a wide and shallow carbonate platform within a lagoon between the shore and a string of reefs. This carbonate platform is nowadays preserved as the Carnian to Norian-age Hauptdolomit and Dachstein Formation. The Kössen Formation represents a period of increased siliciclastic clay input into the lagoon, covering up the carbonate platform with marls and marly limestones instead of pure limestone or dolomite. The Eiberg Member of the Kössen Formation was deposited in the Eiberg basin, a narrow strip of deeper water which developed between the carbonate platform and the shoreline in the later part of the Rhaetian.
The Allgäu Formation is a geologic formation in Austria, Germany and Slovakia. It preserves fossils dating back to the Hettangian to Sinemurian stages of the Early Jurassic period, or Raricostatum to Obtusum in the regional stratigraphy. Initially and formally defined by Jacobshagen (1965). The Allgäu Formation is formerly known as spotted marls (Lias-Fleckenmergel) and spotted marly limestones (Fleckenkalk). The formation is represented by dark-grey bioturbated limestones and marlstone interbeds. It represents basinal hemipelagic facies common in Alpine Tethys regions of Alps, Carpathians and other mountain ranges. Several horizons of the formation are particularly rich in ammonite fauna.
The Steinalm Formation is a geologic formation in the Northern Limestone Alps, in Austria.
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.
The Lunz Formation is a geologic formation in Austria and other Tethyan regions. It is composed of quartz sandstone, shales and claystones, locally with coal interbeds. The basal part of the formation may contain marine fossils. It preserves fossils dated to the Carnian stage of the Triassic period and represents significant siliciclastic input into the European carbonate shelf due to the Carnian Pluvial Event.
The Oberrhaet Formation, also known as the Oberrhaet Limestone, is a Late Triassic (Rhaetian-age) geological formation in Austria. It is a unit of massive dark grey bioclastic limestones, found within the Northern Calcareous Alps. The Oberrhaet Limestone was originally a series of reefs which developed on the northwest edge of the Eiberg Basin, a narrow marine waterway extending along the northwestern tip of the Neotethys Ocean. The center of the Eiberg Basin is nowadays preserved as the Eiberg Member of the Kössen Formation, which was deposited southeast of the Oberrhaet Limestone and interfingers with it in many areas. The Oberrhaet Limestone was very similar to the Dachstein Limestone, which represented carbonate platforms and reefs on the southeast edge of the Eiberg Basin. The most prominent components of the reefs were giant frond-like colonies of Retiophyllia, a scleractinian coral.
The Partnach Formation is a Middle Triassic geologic formation in the eastern Northern Limestone Alps and Western Carpathians, within Austria and Slovakia, Central Europe. The formation consists of alternating grey and green marls and shales and grey limestones, often brecciated, oncolithic and containing clay intraclasts. 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.
Oncodella is an extinct genus of Late Triassic conodont. The genus was given the type species Oncodella idiodentica by Mosher (1968), on the basis of fossils from the Late Triassic of Austria. However, Mosher (1969) later revised the species name to Oncodella paucidentata, since identical fossils from the same area were previously given the name Hindeodella paucidentata by Mostler (1967).
The Travenanzes Formation is a Late Triassic limestone, marl and dolomite formation in the Southern Limestone Alps in Trentino-Alto Adige, Italy.
