The Bjorne Formation is a formation of sandstones and shales in the Canadian Arctic Archipelago. [1] The southern edge of the formation includes petroleum reserves in Melville Island. The basin also includes Mackenzie King Island, Lougheed Island and portions of Prince Patrick Island, Borden Island, Ellef Ringnes Island, Amund Ringnes Island, and Cornwall Island.
The formation underlies the Murray Harbour Formation and overlies the Blind Fiord, Lindstrom and Trold Fiord Formations. [2]
Oil and gas deposits are confirmed through the basin. [1]
The southern and eastern margins are more than 1000 meters, sometimes nearly 2000 meters, thick. [3]
The Qikiqtaaluk Region, Qikiqtani Region or the Baffin Region is the easternmost, northernmost, and southernmost administrative region of Nunavut, Canada. Qikiqtaaluk is the traditional Inuktitut name for Baffin Island. Although the Qikiqtaaluk Region is the most commonly used name in official contexts, several notable public organizations, including Statistics Canada prior to the 2021 Canadian census, use the older term Baffin Region.
Melville Island is an uninhabited member of the Queen Elizabeth Islands of the Arctic Archipelago. With an area of 42,149 km2 (16,274 sq mi), it is the 33rd largest island in the world and Canada's eighth largest island.
The Queen Elizabeth Islands are the northernmost cluster of islands in Canada's Arctic Archipelago, split between Nunavut and the Northwest Territories in Northern Canada. The Queen Elizabeth Islands contain approximately 14% of the global glacier and ice cap area. The southern islands are called the Parry Islands or Parry Archipelago.
Axel Heiberg Island is an uninhabited island in the Qikiqtaaluk Region, Nunavut, Canada. Located in the Arctic Ocean, it is the 32nd largest island in the world and Canada's seventh largest island. According to Statistics Canada, it has an area of 43,178 km2 (16,671 sq mi). It is named after Axel Heiberg.
Ellef Ringnes Island is an uninhabited island and one of the Sverdrup Islands in the Qikiqtaaluk Region, Nunavut, Canada. A member of the Queen Elizabeth Islands and Arctic Archipelago, it is located in the Arctic Ocean, east of Borden Island, and west of Amund Ringnes Island. It has an area of 11,295 km2 (4,361 sq mi), making it the 69th largest island in the world and Canada's 16th largest island. Its highest mount is 260 m (850 ft).
The Sverdrup Islands is an archipelago of the northern Queen Elizabeth Islands, in Nunavut, Canada. The islands, part of the Arctic Archipelago, are situated in the Arctic Ocean, west of Ellesmere Island from 77° to 81° North and 85° to 106° West.
Amund Ringnes Island is an uninhabited island and one of the Sverdrup Islands and Queen Elizabeth Islands in the Qikiqtaaluk Region, Nunavut, Canada. It is located in the Arctic Ocean, between 78 and 79 degrees of latitude. It lies east of Ellef Ringnes Island, west of Axel Heiberg Island. Hassel Sound separates Amund Ringnes Island from Ellef Ringnes Island. Hendriksen Strait is to the south, as is Cornwall Island. Norwegian Bay is to the east, as is Haig-Thomas Island. To the north lies Peary Channel.
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
Oil shale reserves refers to oil shale resources that are economically recoverable under current economic conditions and technological abilities. Oil shale deposits range from small presently economically unrecoverable to large potentially recoverable resources. Defining oil shale reserves is difficult, as the chemical composition of different oil shales, as well as their kerogen content and extraction technologies, vary significantly. The economic feasibility of oil shale extraction is highly dependent on the price of conventional oil; if the price of crude oil per barrel is less than the production price per barrel of oil shale, it is uneconomic.
Hoved Island is part of the Qikiqtaaluk Region of the Canadian territory of Nunavut. The island is located between the Svendsen and Bjorne peninsulas, and within the Baumann Fiord of Ellesmere Island, considered part of the Queen Elizabeth Islands, in the Arctic Archipelago. It comprises an area of 158 km2 (61 sq mi).
The Sverdrup Basin Magmatic Province is a large igneous province located on Axel Heiberg Island and Ellesmere Island, Nunavut, Canada near the rifted margin of the Arctic Ocean at the end of Alpha Ridge.
The Kanguk Formation is a geological formation in the Northwest Territories and Nunavut, Canada whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Bluesky Formation is a stratigraphic unit of Lower Cretaceous age in the Western Canada Sedimentary Basin. It takes the name from the hamlet of Bluesky, and was first described in Shell's Bluesky No. 1 well by Badgley in 1952.
Volcanism in Northern Canada has produced hundreds of volcanic areas and extensive lava formations across Northern Canada. The region's different volcano and lava types originate from different tectonic settings and types of volcanic eruptions, ranging from passive lava eruptions to violent explosive eruptions. Northern Canada has a record of very large volumes of magmatic rock called large igneous provinces. They are represented by deep-level plumbing systems consisting of giant dike swarms, sill provinces and layered intrusions.
The Melville Island oil sands are a large deposit of oil sands on Melville Island in the Canadian Arctic Archipelago.
The Cold Lake oil sands are a large deposit of oil sands located near Cold Lake, Alberta. Cold Lake is east of Alberta's capital, Edmonton, near Alberta's border with Saskatchewan, and a small portion of the Cold Lake field lies in Saskatchewan.
Marie Bay is a fjord on the Northwest tip of Melville Island. Marie Bay lies on the part of Melville Island that is in the Northwest Territories. The Eastern part of the Island is in Nunavut.
The Assistance Formation is a geologic formation located on Devon Island and Ellesmere Island in Nunavut. It preserves fossils dating back to the Permian period. The formation rides along the southeastern edges of the Sverdrup Basin, as well as on Melville Island and Grinnell Peninsula.
The geology of Nunavut began to form nearly three billion years ago in the Archean and the territory preserves some of the world's oldest rock units.
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.
The 100 million barrel tar sand deposit at Marie Bay (Trettin and Hills, 1966) on western Melville Island is held in a possible stratigraphic trap in the Bjorne Formation where conventional oil has been highly degraded by exposure at surface.
