James Edwin Hawley
James Edwin (Ed) Hawley (September 27, 1897 – April 20, 1965) was a Canadian geologist and distinguished Professor of Mineralogy at Queen's University. Biography Hawley was raised in Kingston, Ontario, Canada. He earned both a Bachelor’s and a Master's degree from Queen’s University in 1918 and 1920, respectively. After completing his Masters, Hawley spent three years working in petroleum geology in Alberta, Ecuador, Burma and India. In 1926, he earned his PhD at the University of Wisconsin–Madison. He stayed there for three years as an Assistant Professor. In 1929, Hawley returned to Queen's as Professor and Head of the Department of Mineralogy. His earliest papers in 1929 and 1930, based on research on the generation of oil in rocks by shearing pressures, are classics in the field of petroleum geology. In 1948, he established the school's Spectrographic lab. He held that position until the Mineralogy and Geology Department were combined in 1950. At that time he wa ...

Kingston, Ontario
Kingston is a city in Ontario, Canada. It is located on the north-eastern end of Lake Ontario, at the beginning of the St. Lawrence River and at the mouth of the Cataraqui River (south end of the Rideau Canal). The city is midway between Toronto, Ontario and Montreal, Quebec. Kingston is also located nearby the Thousand Islands, a tourist region to the east, and the Prince Edward County tourist region to the west. Kingston is nicknamed the "Limestone City" because of the many heritage buildings constructed using local limestone. Growing European exploration in the 17th century, and the desire for the Europeans to establish a presence close to local Native occupants to control trade, led to the founding of a French trading post and military fort at a site known as "Cataraqui" (generally pronounced /kætə'ɹɑkweɪ/, "kah-tah-ROCK-way") in 1673. This outpost, called Fort Cataraqui, and later Fort Frontenac, became a focus for settlement. Since 1760, the site of Kingston, Ont ...

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Townships
The Eastern Townships (french: Cantons de l'Est) is an historical administrative region in southeastern Quebec, Canada. It lies between the St. Lawrence Lowlands and the American border, and extends from Granby in the southwest, to Drummondville in the northeast. Since 1987, most of the area is within the administrative region Estrie, and the term Eastern Townships is now used in tourist literature. The name derives from there also being western townships in Ontario. History Before European colonization the area was inhabited by the Abenaki, as attested by many toponyms such as Lake Memphremagog and Massawippi River. Until 1791 the region was organized under the seigneurial system of New France. In 1791 the region was resurveyed under English law. It was divided into counties, which were in turn subdivided into townships. Settlement by Europeans happened in three waves: first from New England, including some loyalists, then from the British Isles, and finally French-Cana ...

Quebec
Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States. Between 1534 and 1763, Quebec was called ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, Quebec b ...

Kirkland Lake
Kirkland Lake is a town and municipality in Timiskaming District in Northeastern Ontario, Canada. The 2016 population, according to Statistics Canada, was 7,981. The community name was based on a nearby lake which in turn was named after Winnifred Kirkland, a secretary of the Ontario Department of Mines in Toronto. The lake was named by surveyor Louis Rorke in 1907. Miss Kirkland never visited the town, and the lake that bore her name no longer exists because of mine tailings. The community comprises Kirkland Lake (Teck Township), as well as Swastika, Chaput Hughes, Bernhardt, and Morrisette Twp. Kirkland Lake was built on gold, but it is equally well known for producing world-famous hockey players. Indeed, legendary hockey broadcaster Foster Hewitt called Kirkland Lake "the town that made the NHL." The town celebrated this via Hockey Heritage North which has been renamed in the meantime to Heritage North. Until January 1, 1972, the town was known as Township of Teck. A by-law w ...

Steep Rock Lake
Steep Rock Lake is a body of water near the township of Atikokan, northern Ontario, Canada. It was originally fed by the Seine River (Ontario), Seine River. Geography Steep Rock Lake and the surrounding region was carved out by retreating glaciers. The lake was carved out as a sprawling "M" shape and is 14 miles long with a surface area of 7 square miles. The lake lies 6–7 km (4 miles) north of Atikokan and 215–225 km (135–140 miles) west of Thunder Bay. The ridges around the water rose 25 meters in places, often with visible outcrops of iron. The area straddles two major Fault (geology), fault systems: The Quetico Fault and the Steep Rock Lake Fault systems. Active speculation about mining the area began as early as 1885, when land deposits were bought by the McKellar and Graham families. However, a patchwork terrain of deep soil, swamp land, and boulders hindered exploitation. Julian Cross, a mining prospector, later came to the area in 1926 and in 1937 through ...

Michipicoten River
The Michipicoten River is a river in Algoma District of northern Ontario, Canada, which flows from Dog Lake and joins with the Magpie River to empty into Michipicoten Bay on Lake Superior near the town of Wawa. This river is in length (including Lochalsh River to the outlet of Wabatongushi Lake) and drains an area of about . The river's name derives from the Ojibwe ''Mishipikwadina,'' meaning "big bluffs," and refers to the large hills located near the river's mouth. From the outlet of Dog Lake, the Michipicoten River flows south through a series of large lakes: Manitowik and Whitefish. Then it flows mostly west to Lake Superior. There are four hydroelectric generating stations on this last section of the river (operated by Brookfield Power Inc.), and at its mouth is the Michipicoten Provincial Park that was the site of a trading post. History A number of prehistoric sites on the Michipicoten River, as well as in the surrounding valley, have been identified by archaeolog ...

Greater Sudbury
Sudbury, officially the City of Greater Sudbury is the largest city in Northern Ontario by population, with a population of 166,004 at the 2021 Canadian Census. By land area, it is the largest in Ontario and the List of the largest cities and towns in Canada by area, fifth largest in Canada. It is administratively a List of census divisions of Ontario#Single-tier municipalities, single-tier municipality and thus is not part of any district, county, or regional municipality. The City of Greater Sudbury is separate from, but entirely surrounded by the Sudbury District. The city is also referred to as "Grand Sudbury" among Franco-Ontarian, Francophones. The Sudbury region was inhabited by the Ojibwe people of the Algonquin people, Algonquin group for thousands of years prior to the founding of Sudbury after the discovery of nickel ore in 1883 during the construction of the transcontinental railway. Greater Sudbury was formed in 2001 by merging the cities and towns of the former Regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawleyite
Hawleyite is a rare sulfide mineral in the sphalerite group, dimorphous and easily confused with greenockite. Chemically, it is cadmium sulfide, and occurs as a bright yellow coating on sphalerite or siderite in vugs, deposited by meteoric water. It was discovered in 1955 in the Hector-Calumet mine, Keno-Galena Hill area, Yukon Territory and named in honour of mineralogist James Edwin Hawley (1897–1965), a professor at Queen's University in Ontario, Canada.

Mohs Scale Of Mineral Hardness
The Mohs scale of mineral hardness () is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. The scale was introduced in 1812 by the German geologist and mineralogist Friedrich Mohs, in his book ''"Versuch einer Elementar-Methode zur naturhistorischen Bestimmung und Erkennung der Fossilien"''; it is one of several definitions of hardness in materials science, some of which are more quantitative. The method of comparing hardness by observing which minerals can scratch others is of great antiquity, having been mentioned by Theophrastus in his treatise ''On Stones'', , followed by Pliny the Elder in his ''Naturalis Historia'', . The Mohs scale is useful for identification of minerals in the field, but is not an accurate predictor of how well materials endure in an industrial setting – ''toughness''. Minerals The Mohs scale of mineral hardness is based on the ability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromatography
In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the ''mobile phase'', which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the ''stationary phase'' is fixed. Because the different constituents of the mixture tend to have different affinities for the stationary phase and are retained for different lengths of time depending on their interactions with its surface sites, the constituents travel at different apparent velocities in the mobile fluid, causing them to separate. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation. Chromatography may be preparative or analytical. The purpose of preparativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shear (geology)
Boudinaged quartz vein (with strain fringe) showing ''Fault (geology)">sinistral shear sense'', Starlight Pit, Fortnum Gold Mine, Western Australia In geology, shear is the response of a rock to deformation usually by compressive stress and forms particular textures. Shear can be homogeneous or non-homogeneous, and may be pure shear or simple shear. Study of geological shear is related to the study of structural geology, rock microstructure or rock texture and fault mechanics. The process of shearing occurs within brittle, brittle-ductile, and ductile rocks. Within purely brittle rocks, compressive stress results in fracturing and simple faulting. Rocks Rocks typical of shear zones include mylonite, cataclasite, S-tectonite and L-tectonite, pseudotachylite, certain breccias and highly foliated versions of the wall rocks. Shear zone A shear zone is a tabular to sheetlike, planar or curviplanar zone composed of rocks that are more highly strained than rocks adjacent to ...
