Semisopochnoi Island or Unyak Island is part of the Rat Islands group in the western Aleutian Islands of Alaska. The island is uninhabited and provides an important nesting area for maritime birds. The island is of volcanic origin, containing several volcanoes including Mount Cerberus. It has a land area of 85.558 square miles, measuring 11 miles (18 km) in length and 12 miles (20 km) in width.
John Bicknell Auden was an English geologist and explorer, older brother of the poet W. H. Auden, who worked for many years in India with the Geological Survey of India and later with the Food and Agriculture Organization. He studied the Himalayan strata, particularly the Krol Belt where he recognized rocks from the Peninsula thrusting north into the Himalayas. He also studied groundwater and was involved in studying the geology of many dam sites in India. Auden's Col is named after him.
The Baie Verte Peninsula is a large peninsula on the north central coast of the island of Newfoundland in the Canadian province of Newfoundland and Labrador.
Smith Sound is a zigzag 24 kilometre inner region of Trinity Bay. This sound is one of the longest portions of inshore waterways in Newfoundland, located on its north-eastern coast in the Canadian province of Newfoundland and Labrador. Bonavista Peninsula is to the north of the sound, while Random Island is to the south. The waters that make up the sound is a continuous channel that encircles Random Island, broken only by a narrow channel located at Clarenville where a causeway was built to provide access to the communities on Random Island. The channel on the south side of Random Island is North West Arm.
Newfoundland is a large island off the east coast of the North American mainland and the most populous part of the Canadian province of Newfoundland and Labrador. It has 29 percent of the province's land area. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait. It blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the world's largest estuary. Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon.
The Jeanne d'Arc Basin is an offshore sedimentary basin located about 340 kilometres to the basin centre, east-southeast of St. John's, Newfoundland and Labrador. This basin formed in response to the large scale plate tectonic forces that ripped apart the super-continent Pangea and also led to sea-floor spreading in the North Atlantic Ocean. This basin is one of a series of rift basins that are located on the broad, shallow promontory of continental crust known as the Grand Banks of Newfoundland off Canada's east coast. The basin was named after a purported 20 metres shoal labelled as "Ste. Jeanne d'Arc" on out-dated bathymetric charts and which was once thought to represent a local exposure of basement rocks similar to the Virgin Rocks.
The Chapel Island Formation is a sedimentary formation from the Burin Peninsula, Newfoundland, Canada. It is a succession of siliciclastic deposits, over 1,000 metres (3,300 ft) thick, that were deposited during the latest Ediacaran and earliest Cambrian.
The Chamberlain's Brook Formation is a thin but distinctive geologic formation of dark red calcareous mudstones that crops out from Rhode Island to Massachusetts and, Nova Scotia, New Brunswick and Newfoundland. It preserves fossils, including trilobites, dating back to the lower mid-Cambrian period. Its lowermost member is the Braintree Member and the uppermost member is the Fossil Brook Member.
The Brigus Formation is a fossiliferous upper lower Cambrian geologic formation in Newfoundland and Labrador.
Bailiaspis Resser, 1936, is a Middle Cambrian (Miaolingian) trilobite genus belonging to the Family Conocoryphidae Angelin, 1854. Within the Acado-Baltic region, the genus ranges from Wuliuan into Guzhangian age strata.
The Random Formation is a rock unit in Newfoundland dating to the early Cambrian period, dominated by tidal quartz arenites deposited in a near-shore environment, but also incorporating intertidal and open-shelf deposits, including glauconitic and mud-cracked mudstones, and red channel sandstones. It was deposited quickly and is approximately 175 m thick. The Blue Pinion Formation was originally recognized as a separate formation, but is now interpreted as an expression of the Random Formation.
The Smith Point Formation is an Early Cambrian, fossil-rich, pink to brick red limestone formation cropping out in Newfoundland.
Crown Hill Formation is a late Ediacaran volcanic non-marine sedimentary formation in Newfoundland. It's topped off with a bright red conglomerate, with silt and arkose sands of similar hue too.
Manuels River Formation is a Middle Cambrian (Drumian) geological formation cropping out in the Random Island area of Newfoundland and elsewhere?. Its black/dark brown, finely laminated mudstones and thicker-bedded siltstones are occasionally interrupted by thin yellowish silty limestone horizons.
The Connecting Point Group is a Late Neoproterozoic geological formation cropping out on the Avalon Peninsula of Newfoundland, dominated by deep marine turbidite deposits.
The Musgravetown Group is a terminal Ediacaran stratigraphic group of terrestrialish sandstones, lavas and tuffs cropping out in Newfoundland.
The Love Cove Group is a metamorphosed volcaniclastic sedimentary group cropping out in southeastern Newfoundland. Strata from towards the middle of the formation have been dated to 620 ± 1 million years ago.
The Rocky Harbour Formation is a formation cropping out in Newfoundland. Its depositional setting was deltaic, with sediments showing the influence of tides and waves.
The geology of Newfoundland and Labrador includes basement rocks formed as part of the Grenville Province in the west and Labrador and the Avalonian microcontinent in the east. Extensive tectonic changes, metamorphism and volcanic activity have formed the region throughout Earth history.
The Canadian Arctic Rift System is a major North American geological structure extending from the Labrador Sea in the southeast through Davis Strait, Baffin Bay and the Arctic Archipelago in the northwest. It consists of a series of interconnected rifts that formed during the Paleozoic, Mesozoic and Cenozoic eras. Extensional stresses along the entire length of the rift system have resulted in a variety of tectonic features, including grabens, half-grabens, basins and faults.
