The Canadian Shield is a collage of Archean plates and accreted juvenile arc terranes and sedimentary basins of the Proterozoic Eon that were progressively amalgamated during the interval 2.45–1.24 Ga, with the most substantial growth period occurring during the Trans-Hudson orogeny, between c. 1.90–1.80 Ga. [5] The Canadian Shield was the ...
Selected geological features near the Skjaldbreiður shield volcano.(red outline). Light violet shading shows the current surface area of the Skjaldbreiður lava flows. Shading also shows: calderas, central volcanoes and fissure swarms, subglacial terrain above 1,100 m (3,600 ft), and seismically active areas. Clicking on the image enlarges to ...
This list of shield volcanoes includes active, dormant and extinct shield volcanoes. Shield volcanoes are one of the three types [ specify ] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)
Mount Edziza, a stratovolcano in northwestern British Columbia A topographic map of Canada, showing elevations shaded from green (lower) to brown (higher). Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes ...
The basin is located on the Canadian Shield in the city of Greater Sudbury, Ontario. The former municipalities of Rayside-Balfour, Valley East and Capreol lie within the Sudbury Basin, which is referred to locally as "The Valley". The urban core of the former city of Sudbury lies on the southern outskirts of the basin.
Its principal feature is an 18-mile (29 km) long linear zone of shield volcanoes, cinder cones, and flows with volumes of up to 23 cubic miles (96 km 3) with the highest peak, Lemei Rock. The shield volcanoes, which form the backbone of the volcanic field, are located on the northern and southern sides of the field.
Sif Mons is an active shield volcano located in Eistla Regio on Venus.It has a diameter of 500 kilometers (310 mi) and a height of 2.2 kilometers (1.4 mi). The volcano is one of the few identified active extraterrestrial volcanoes, having last erupted between 1990 and 1992.
Canadian Shield. The Canadian Shield, Precambrian shield, makes up the bedrock geology highlighted by rocks and lakes [2] and a boreal forest area. There are transitional areas between boreal and tundra flora. [3] The lower boundary of the Canadian Shield cuts across the province diagonally from the latitude 57 degrees in the northwest to 54 ...
