Hall Peninsula
The Hall Peninsula is a peninsula on the southern end of Baffin Island, in Nunavut, Canada. It lies between Frobisher Bay on the west, and the Cumberland Sound on the east between 62°40'N and 65°10'W. The Hall Peninsula is part of the Arctic Tundra biome—the world's coldest and driest biome. The Blunt Peninsula extends off the southeastern part of the Hall Peninsula. The Hall Peninsula includes the Chidliak Kimberlite Province, which had been found to include diamond Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.

Baffin Island
Baffin Island (formerly Baffin Land), in the Canadian territory of Nunavut, is the largest island in Canada, the second-largest island in the Americas (behind Greenland), and the fifth-largest island in the world. Its area is (slightly smaller than Thailand) with a population density of 0.03/km2; the population was 13,039 according to the 2021 Canadian census; and it is located at . It also contains the city of Iqaluit (with a population of around 7,000), which is the capital of Nunavut. Name The Inuktitut name for the island is , which means "very big island" ( "island" + "very big") and in Inuktitut syllabics is written as . This name is used for the administrative region the island is part of ( Qikiqtaaluk Region), as well as in multiple places in Nunavut and the Northwest Territories, such as some smaller islands: Qikiqtaaluk in Baffin Bay and Qikiqtaaluk in Foxe Basin. Norse explorers are believed to have referred to it as ("stone land"). In 1576, English seaman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nunavut
Nunavut is the largest and northernmost Provinces and territories of Canada#Territories, territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the ''Nunavut Act'' and the Nunavut Land Claims Agreement, ''Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for self-government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the territorial evolution of Canada, first major change to Canada's political map in half a century since the province of Newfoundland and Labrador, Newfoundland (now Newfoundland and Labrador) was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the list of the largest country subdivisions by area, fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland). The capital Iqaluit (formerly "Frobisher Bay"), on Baffin Island in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frobisher Bay
Frobisher Bay is an inlet of the Davis Strait in the Qikiqtaaluk Region of Nunavut, Canada. It is located in the southeastern corner of Baffin Island. Its length is about and its width varies from about at its outlet into the Davis Strait to roughly towards its inner end. The capital of Nunavut, Iqaluit, known as Frobisher Bay from 1942 to 1987, lies near the innermost end of the bay. Geography Frobisher Bay has a tapered shape formed by two flanking peninsulas, the Hall Peninsula to the northeast, and the Meta Incognita Peninsula to the southwest. The Bay's funnel like shape ensures that the tidal variance at Iqaluit each day is about . This shape is due to the large outlet glacier centred over Foxe Basin during the Quaternary glaciation (Pleistocene), which gouged the Bay's basin, now flooded by the sea.Frobisher Bay< ...

Cumberland Sound
Cumberland Sound (; Inuit: ''Kangiqtualuk'') is an Arctic waterway in the Qikiqtaaluk Region, Nunavut, Canada. It is a western arm of the Labrador Sea located between Baffin Island's Hall Peninsula and the Cumberland Peninsula. It is approximately long and wide. Other names are ''Cumberland Straits,'' ''Hogarth Sound'', and ''Northumberland Inlet.'' Small islands litter the stretch of water which was formed from glacial activity and meltwater produced from the receding glacier. The only settlement located on the shore of the sound on the Cumberland Peninsula is Pangnirtung. John Davis, the English explorer, went part way up the sound in 1585. After that it was unvisited by Europeans until 1839, when the British whaler and explorer William Penny persuaded Eenoolooapik (brother of interpreter and guide Taqulittuq) to show him the inland sea. The Inuk had described the sound, known to him as ''Tenudiackbeek'', as full of whales, and soon the British set up a whaling st ...

Arctic
The Arctic (; . ) is the polar regions of Earth, polar region of Earth that surrounds the North Pole, lying within the Arctic Circle. The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway (Nordland, Troms, Finnmark, Svalbard and Jan Mayen), northernmost Sweden (Västerbotten, Norrbotten and Lapland (Sweden), Lappland), northern Finland (North Ostrobothnia, Kainuu and Lapland (Finland), Lappi), Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), the United States (Alaska), Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), and northern Iceland (Grímsey and Kolbeinsey), along with the Arctic Ocean and adjacent seas. Land within the Arctic region has seasonally varying cryosphere, snow and ice cover, with predominantly treeless permafrost under the tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, a tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: #Arctic, Arctic, Alpine tundra, Alpine, and #Antarctic, Antarctic. Tundra vegetation is composed of dwarf shrubs, Cyperaceae, sedges, Poaceae, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained greenhouse gases into the atmosphere, creating Climate change feedback, a feedback cycle t ...

Biome
A biome () is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. In 1935, Tansley added the climatic and soil aspects to the idea, calling it ''ecosystem''. The International Biological Program (1964–74) projects popularized the concept of biome. However, in some contexts, the term ''biome'' is used in a different manner. In German literature, particularly in the Walter terminology, the term is used similarly as '' biotope'' (a concrete geographical unit), while the biome definition used in this article is used as an international, non-regional, terminology—irrespectively of the continent in which an area is present, it takes the same biome name—and corresponds to his "zonobiome", "orobiome" and "pedobiome" (biomes determined by climate zone, altitude or soil). In the Brazilian literature, the term ''biome'' is sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chidliak Kimberlite Province
The Chidliak Kimberlite Province is located in the Hall Peninsula of southern Baffin Island, Nunavut, Canada. The first kimberlite there was discovered in July 2008 during exploration conducted by BHP Billiton and Peregrine Diamonds Ltd. By 2012, more than 60 kimberlites had been found, seven of which included some gem-quality diamonds.Pell, J., Grütter H., Neilson S., Lockhart, G., Dempsey, S. and Grenon, H. 2013.

Diamond
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) can color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimberlite Pipe
Volcanic pipes or volcanic conduits are subterranean geological structures formed by the violent, supersonic eruption of deep-origin volcanoes. They are considered to be a type of '' diatreme''. Volcanic pipes are composed of a deep, narrow cone of solidified magma (described as "carrot-shaped"), and are usually largely composed of one of two characteristic rock types — kimberlite or lamproite. These rocks reflect the composition of the volcanoes' deep magma sources, where the Earth is rich in magnesium. They are well known as the primary source of diamonds, and are mined for this purpose. Volcanic pipes are relatively rare by this definition based on minerals and depth of the magma source, but on the other hand volcanic diatremes are common, indeed the second commonest form of volcanic extrusion (that is magma that reaches the surface). Formation Volcanic pipes form as the result of violent eruptions of deep-origin volcanoes. These volcanoes originate at least three times as ...
