Kapp Toscana Group (Svalbard)

The Kapp Toscana Group is a geologic group in Svalbard and Jan Mayen in the Barents Sea, Norway. [1]

Contents

Description

The group dates back to the Late Triassic, and comprises the rock formations of Tschermakfjellet, De Geerdalen and Wilhelmøya. [2] The group is named from the headland of Kapp Toscana at the southern side of Van Keulenfjorden in Wedel Jarlsberg Land at Spitsbergen, Svalbard. [3] The thickness of the group varies from 8–500 metres (26–1,640 ft) of deltaic shales with interbedded sandstones. [4]

The Kapp Toscana Group was initially defined as a formation, [5] but has later become a group. [6] The type section was taken from Kapp Toscana at Van Keulenfjorden, where the thickness of the unit was 200 metres (660 ft), while its two members Tschermakfjellet and De Geerdalen had type sections from Botneheia.

Svalbard and Jan Mayen Two parts of Norway under separate jurisdictions

Svalbard and Jan Mayen is a statistical designation defined by ISO 3166-1 for a collective grouping of two remote jurisdictions of Norway: Svalbard and Jan Mayen. While the two are combined for the purposes of the International Organization for Standardization (ISO) category, they are not administratively related. This has further resulted in the country code top-level domain .sj being issued for Svalbard and Jan Mayen, and ISO 3166-2:SJ. The United Nations Statistics Division also uses this code, but has named it Svalbard and Jan Mayen Islands.

Greenland Sea body of water that borders Greenland to the west, the Svalbard archipelago to the east, south of the Fram Strait

The Greenland Sea is a body of water that borders Greenland to the west, the Svalbard archipelago to the east, Fram Strait and the Arctic Ocean to the north, and the Norwegian Sea and Iceland to the south. The Greenland Sea is often defined as part of the Arctic Ocean, sometimes as part of the Atlantic Ocean. However, definitions of the Arctic Ocean and its seas tend to be imprecise or arbitrary. In general usage the term "Arctic Ocean" would exclude the Greenland Sea. In oceanographic studies the Greenland Sea is considered part of the Nordic Seas, along with the Norwegian Sea. The Nordic Seas are the main connection between the Arctic and Atlantic oceans and, as such, could be of great significance in a possible shutdown of thermohaline circulation. In oceanography the Arctic Ocean and Nordic Seas are often referred to collectively as the "Arctic Mediterranean Sea", a marginal sea of the Atlantic.

Chinle Formation Geological formation in the western US

The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. The Chinle is controversially considered to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle is sometimes colloquially named as a formation within the Dockum Group in New Mexico and in Texas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains.

Kapp Muyen

Kapp Muyen is a cape just 107 m (350 ft) west of Beerenberg, the stratovolcano which forms the northeastern end of the Norwegian island of Jan Mayen. The point is named after the Dutch whaling master Willem Cornelisz. van Muyden, who was among the first to catch whales at Jan Mayen.

Ingebrigtsenbukta

Ingebrigtsenbukta is a bay at the south shore of Van Keulenfjorden inside Sør-Spitsbergen National Park. The bay is approximately 3 km wide, running from Kapp Toscana in the west to Ålesundneset in the east. The bay was named after Norwegian whaler Morten Andreas Ingebrigtsen.

Kapp Hammerfest is a headland on Svenskøya in Kong Karls Land, Svalbard. It is the most southern point of Svenskøya, and the headland has a length of about 1.5 kilometers. The headland is named after the Norwegian city of Hammerfest. North of the headland, at the western side of the Svenskøya, is Kyrkjevika with Antarcticøya and other smaller islands.

Mariaholmen

Mariaholmen is an islet in Nathorst Land at the mouth of Van Mijenfjorden at Spitsbergen, Svalbard. It is located south of Akseløya, between Akseløya and Måseneset. While Akselsundet north of Akseløya is regarded as the main entrance to Van Mijenfjorden, Mariasundet between Mariaholmen and Måseneset is also navigable.

It is present on the western edge of the Western Canada Sedimentary Basin in the foothills and Rocky Mountains of western Alberta and northeastern British Columbia. It includes marine fossils from the time shortly after the Permian-Triassic extinction event.

De Geerdalen

De Geerdalen is a valley in Nordenskiöld Land at Spitsbergen, Svalbard. It is named after Swedish geologist and Arctic explorer Gerard De Geer. The mountain pass of Kreklingpasset divides De Geerdalen from Helvetiadalen. The river of De Geerelva flows through the valley, and debouches into Sassenfjorden at Elveneset.

Kapp Toscana is a headland at the southern side of Van Keulenfjorden in Wedel Jarlsberg Land at Spitsbergen, Svalbard. It is named after an Austrian family. West of the headland is the bay of Bourbonhamna, extending from Kapp Toscana to Kapp Madrid. East of the headland is the bay of Ingebrigtsenbukta, extending from Kapp Toscana to Ålesundneset.

Geology of Svalbard

The geology of Svalbard encompasses the geological description of rock types found in Svalbard, and the associated tectonics and sedimentological history of soils and rocks. The geological exploration of Svalbard is an ongoing activity, and recent understandings may differ from earlier interpretations.

The Tschermakfjellet Formation is a geological formation in Svalbard, Norway, a subunit of the Kapp Toscana Group. The formation dates to the Late Triassic.

Río Cachirí Group Geological group in the Venezuelan Andes

The Río Cachirí Group is a geological group of the Cesar-Ranchería Basin, Colombia and the Serranía del Perijá of the northernmost Colombian and Venezuelan Andes. The group of shales, sandstones and limestones is of Devonian age and has a maximum thickness in the Venezuelan section of 2,438 metres (7,999 ft). The group contains abundant fauna; crinoids, bryozoa, brachiopods and molluscs have been found in the group.

The Glorieta Sandstone is a geologic formation in New Mexico. It preserves fossils characteristic of the Kungurian age of the Permian geology.

The Venado Formation is a geological formation of the Agua Blanca Group, in the Eastern Ranges of the Colombian Andes, cropping out along the Venado River in northern Huila. The sequence of pyrite containing dark grey micaceous shales interbedded with siltstones and sandstones dates to the Ordovician period; Middle to Late Floian epoch, and has a maximum thickness of 670 metres (2,200 ft) in the type section.
