Uchi Subprovince

Last updated

The Uchi Subprovince is a Neoarchean volcanic sequence in Manitoba, Canada. It is at the southern margin of the North Caribou terrane and comprises a number of greenstone belts, which contains volcanic rocks that record some 280 million years of volcanism.[ citation needed ]

Not to be confused with archaea, in spite of biological discussion commonly alluding to the only life forms of that era, e.g. microbes

Manitoba Province of Canada

Manitoba is a province at the longitudinal centre of Canada. It is often considered one of the three prairie provinces and is Canada's fifth-most populous province with its estimated 1.3 million people. Manitoba covers 649,950 square kilometres (250,900 sq mi) with a widely varied landscape, stretching from the northern oceanic coastline to the southern border with the United States. The province is bordered by the provinces of Ontario to the east and Saskatchewan to the west, the territories of Nunavut to the north, and Northwest Territories to the northwest, and the U.S. states of North Dakota and Minnesota to the south.

Canada Country in North America

Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border. Its capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra. Consequently, its population is highly urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies widely across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons.

Lava Forks Provincial Park is a provincial park in northern British Columbia, Canada. It is the site of Canada's most recent volcanic eruption, which occurred in 1904 at Lava Fork.

The Pyramid, also called Pyramid Dome, is a young lava dome on the northeast flank of Mount Edziza in British Columbia, Canada. It is on the northeastern edge of the Tencho Glacier and represents several different styles of volcanic activity on the Mount Edziza complex. It is in the Northern Cordilleran Volcanic Province and last erupted during the Pleistocene period.

The Bridge River Cones, sometimes referred to as the Lillooet Cones and Salal Creek Cones, is the name given to a volcanic field located on the north flank of the upper Bridge River, about 40 km (25 mi) west of the town of Gold Bridge. The cones are in the lee of the Lillooet Icecap and sit astride a group of passes between the Bridge River, which flows W-E to their south, and the Lord River, which flows north to the Taseko Lakes in the Chilcotin District.

Pemberton Volcanic Belt

The Pemberton Volcanic Belt is an eroded Oligocene-Miocene volcanic belt at a low angle near the Mount Meager massif, British Columbia, Canada. The Garibaldi and Pemberton volcanic belts appear to merge into a single belt, although the Pemberton is older than the Garibaldi Volcanic Belt. The Pemberton Volcanic Belt is one of the geological formations comprising the Canadian Cascade Arc. It formed as a result of subduction of the former Farallon Plate.

Volcanology of Canada

Volcanology of Canada includes lava flows, lava plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes, calderas, diatremes, and maars, along with examples of more less common volcanic forms such as tuyas and subglacial mounds. It has a very complex volcanological history spanning from the Precambrian eon at least 3.11 billion years ago when this part of the North American continent began to form.

Ember Ridge

Ember Ridge is a volcanic mountain ridge associated with the Mount Cayley volcanic field in British Columbia, Canada. Ember Ridge is made of a series of steep-sided domes of glassy, complexly jointed, hornblende-phyric basalt with the most recent eruptions during the Holocene. The domes have structural similarities which indicate that the domes are similar in age and could have formed by the same foundation.

The Bennett Lake Volcanic Complex (BLVC) is a huge 50-million-year-old extinct caldera complex that spans across the British Columbia-Yukon border in Canada. It is located near the western end of the West Arm of Bennett Lake. The caldera complex is surrounded by granitic rocks containing pendants.

The Skukum Group is a 55-million-year-old volcanic group in northern British Columbia and southern Yukon, Canada. It consists of discrete calderas in a linear range from the south end of Atlin Lake to Bennett Lake, then to Aishihik Lake. The cluster of rocks crowds the Mount Skukum gold deposit southwest of Whitehorse. One of the calderas within the group is the Bennett Lake Volcanic Complex.

Powder Mountain Icefield glacier in Canada

The Powder Mountain Icefield, also called the Powder Mountain Icecap and the Cayley Icefield, is a glacial field in the Pacific Ranges of southwestern British Columbia, Canada, about 20 kilometres (12 mi) west of Whistler and about 90 kilometres (56 mi) north of Vancouver. On the west side of the icefield is the valley of the Squamish River, while on its east is the Callaghan Valley, which is the setting for the Nordic facilities for the 2010 Winter Olympics.

Cauldron Dome is a tuya in the Mount Cayley volcanic field, British Columbia, Canada. Cauldron Dome is made of coarsely plagioclase-orthophyroxene-phyric andesite lava flows and last erupted during the Holocene. It is in the Garibaldi Volcanic Belt, a portion of the Canadian Cascade Arc.

Sezill Volcano is a lava dome in Mount Edziza Provincial Park of northern British Columbia, Canada. It is thought to have formed and last erupted during the Miocene period. The volcano gets its name from being adjacent to Sezill Creek.

Mess Lake Lava Field

The Mess Lake Lava Field is a volcanic field associated with the Mount Edziza volcanic complex of the Northern Cordilleran Volcanic Province in northwestern British Columbia, Canada. It lies northwest of the Spectrum Range on the Kitsu Plateau and consists of young basaltic lava flows and tephra. The source for the basaltic lava and tephra was three cinder cones, including Mess Lake Cone and The Ash Pit, which may be the youngest volcanic feature of the Mount Edziza volcanic complex.

    Geographic coordinate system Coordinate system

    A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
