Dundas Island (Nunavut)
Dundas Island is a member of the Queen Elizabeth Islands and the Arctic Archipelago in the territory of Nunavut. It is an irregularly shaped island located between Devon Island and Baillie-Hamilton Island. The smaller Margaret Island is to the east of Dundas. Dundas Island is named in honour of Henry Dundas, 1st Viscount Melville, Viscount Melville and British Secretary of State for the Home Department. After showings were discovered on Dundas Island in 1972, geochemical sampling, mapping, and surveying began the following year. Canadian mining company Cominco (now part of Teck Resources) staked claims in 1974 and drilling occurred at high grade lead-zinc showings at the Thumb Mountain Formation and Disappointment Bay Formation in 1975. Cominco began IP surveys in 1981. Robert John McGhee's 1981 research found evidence of Late Dorset warm-season dwellings on Dundas Island. There is a second, much smaller (longest axis ~500 m) Dundas Island also in Nunavut, off Boothia Penins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Canada
Northern Canada, colloquially the North or the Territories, is the vast northernmost region of Canada variously defined by geography and politics. Politically, the term refers to the three Provinces_and_territories_of_Canada#Territories, territories of Canada: Yukon, Northwest Territories and Nunavut. This area covers about 48 per cent of Canada's total land area, but has less than 1 per cent of demographics of Canada, Canada's population. The terms "northern Canada" or "the North" may be used in contrast with ''the far north'', which may refer to the Canadian Arctic, the portion of Canada that lies north of the Arctic Circle, east of Alaska and west of Greenland. However, in many other uses the two areas are treated as a single unit. __TOC__ Definitions Subdivisions As a social rather than political region, the Canadian North is often subdivided into two distinct regions based on climate, the ''near north'' and the ''far north''. The different climates of these two regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islands Of The Queen Elizabeth Islands
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas Of Canada
The Atlas of Canada (french: L'Atlas du Canada) is an online atlas published by Natural Resources Canada that has information on every city, town, village, and hamlet in Canada. It was originally a print atlas, with its first edition being published in 1906 by geographer James White and a team of 20 cartographers. Much of the geospatial data used in the atlas is available for download and commercial re-use from the Atlas of Canada site or from GeoGratis. Information used to develop the atlas is used in conjunction with information from Mexico and the United States to produce collaborative continental-scale tools such as the North American Environmental Atlas The ''North American Environmental Atlas'' is an interactive mapping tool created through a partnership of government agencies in Canada, Mexico and the United States, along with the Commission for Environmental Cooperation, a trilateral internati ....

King William Island
King William Island (french: Île du Roi-Guillaume; previously: King William Land; iu, Qikiqtaq, script=Latn) is an island in the Kitikmeot Region of Nunavut, which is part of the Arctic Archipelago. In area it is between and making it the 61st-largest island in the world and Canada's 15th-largest island. Its population, as of the 2021 census, was 1,349, all of whom live in the island's only community, Gjoa Haven. While searching for the Northwest Passage, a number of polar explorers visited, or spent their winters on, King William Island. Geography The island is separated from the Boothia Peninsula by the James Ross Strait to the northeast, and the Rae Strait to the east. To the west is the Victoria Strait and beyond it Victoria Island. Within the Simpson Strait, to the south of the island, is Todd Island, and beyond it, further to the south, is the Adelaide Peninsula. Queen Maud Gulf lies to the southwest. Some places on the coast are: (counter clockwise from the nort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boothia Peninsula
Boothia Peninsula (; formerly ''Boothia Felix'', Inuktitut ''Kingngailap Nunanga'') is a large peninsula in Nunavut's northern Canadian Arctic, south of Somerset Island. The northern part, Murchison Promontory, is the northernmost point of mainland Canada. Geography Bellot Strait (Ikirahaq) separates the peninsula from Somerset Island to the north. Babbage Bay is on the east coast, as is Abernethy Bay, just to the south. The community of Taloyoak lies in the far south and is the peninsula's only significant population centre. Paisley Bay is on the west coast, as is Wrottesley Inlet (between Paisley Bay and Bellot Strait). Prior to the detachment of Nunavut in 1999, the Boothia Peninsula and the nearby Melville Peninsula were the only parts of mainland Canada that belonged to the District of Franklin in the then Northwest Territories. The balance of the District of Franklin was all situated within the Arctic Archipelago. Exploration John Ross was forced by ice to s ...

Dorset Culture
The Dorset was a Paleo-Eskimo culture, lasting from to between and , that followed the Pre-Dorset and preceded the Thule people (proto-Inuit) in the North American Arctic. The culture and people are named after Cape Dorset (now Kinngait) in Nunavut, Canada, where the first evidence of its existence was found. The culture has been defined as having four phases due to the distinct differences in the technologies relating to hunting and tool making. Artifacts include distinctive triangular end-blades, oil lamps () made of soapstone, and burins. The Dorset were first identified as a separate culture in 1925. The Dorset appear to have been extinct by 1500 at the latest and perhaps as early as 1000. The Thule people, who began migrating east from Alaska in the 11th century, ended up spreading through the lands previously inhabited by the Dorset. There is no strong evidence that the Inuit and Dorset ever met. Modern genetic studies show the Dorset population were distinct from later ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Queen Elizabeth Islands
The Queen Elizabeth Islands (french: Îles de la Reine-Élisabeth; formerly Parry Islands or Parry Archipelago) 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 (excluding the inland and shelf ice sheets of Greenland and Antarctica). Geography The islands, together in area, were renamed as a group after Elizabeth II on her coronation as Queen of Canada in 1953. The islands cover an area approximately the shape of a right triangle, bounded by the Nares Strait on the east, Parry Channel on the south and the Arctic Ocean to the north and west. Most are uninhabited although the Natural Resources Canada's Climate Change Geoscience Program Earth Sciences Sector (ESS), has monitors on the islands. In 1969 Panarctic Oils, now part of Suncor Energy, began operating exploration oil wells in the Franklini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Dundas, 1st Viscount Melville
Henry Dundas, 1st Viscount Melville, PC, FRSE (28 April 1742 – 28 May 1811), styled as Lord Melville from 1802, was the trusted lieutenant of British Prime Minister William Pitt and the most powerful politician in Scotland in the late 18th century. Dundas was instrumental in the encouragement of the Scottish Enlightenment, in the prosecution of the war against France, and in the expansion of British influence in India. Prime Minister Pitt appointed him Lord of Trade (1784–1786), Home Secretary (1791–1794), President of the Board of Control for Indian Affairs (1793–1801), Secretary at War (1794–1801) and First Lord of the Admiralty (1804–1805). His deft and almost total control of Scottish politics during a long period in which no monarch visited the country led to him being nicknamed "King Harry the Ninth", the "Grand Manager of Scotland" (a play on the masonic office of Grand Master of Scotland), the "Great Tyrant" and "The Uncrowned King of Scotland".
