Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and ...

Haidoterminus
''Haidoterminus'' is an extinct genus of ant in the Formicidae subfamily Haidomyrmecinae, and is one of only nine genera placed in this subfamily. The genus contains a single described species ''Haidoterminus cippus'' and is known from one Late Cretaceous fossil which has been found in North America. History and classification ''Haidoterminus'' is known from a solitary adult fossil, the holotype, specimen number "UASM 332546" donated for study by Mark Elaschuk. At the time of description, the specimen was residing in the Strickland Entomology Museum, part of the University of Alberta. The holotype specimen is composed of a mostly complete worker caste adult female which has been preserved as an inclusion in a transparent chunk of clear yellow Canadian amber. The amber specimen was recovered from deposits of the Foremost Formation near Grassy Lake, Alberta, Canada. Canadian amber has been dated to an age of approximately 79–78 million years old, placing it in the Campanian of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amber
Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects."Amber" (2004). In Maxine N. Lurie and Marc Mappen (eds.) ''Encyclopedia of New Jersey'', Rutgers University Press, . Amber is used in jewelry and has been used as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions. Amber occurring in coal seams is also called resinite, and the term ''ambrite'' is applied to that found specifically within New Zealand coal seams. Etymology The English word ''amber'' derives from Arabic (ultimately from Middle Persian ''ambar'') via Middle Latin ''ambar'' and Middle French ''ambre''. The word was adopted in Middle English in the 14th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinosaur Provincial Park
Dinosaur Provincial Park is a UNESCO World Heritage Site situated a two hour drive east of Calgary, Alberta, Canada; or , about a half-hour drive northeast of Brooks. The park is situated in the Red Deer River valley, which is noted for its striking badland topography, and abundance of dinosaur fossils. The park is well known for being one of the richest dinosaur fossil locales in the world. Fifty-eight dinosaur species have been discovered at the park and more than 500 specimens have been removed and exhibited in museums around the globe. The renowned fossil assemblage of nearly 500 species of life, from microscopic fern spores to large carnivorous dinosaurs, justified its becoming a World Heritage Site in 1979. Dinosaur Provincial Park Visitor Centre The Dinosaur Provincial Park Visitor Centre features exhibits about dinosaurs, fossils, and the geology and natural history of the park. There is a video theatre, fossil prep lab area, and a gift shop. Public programs are offere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicine Hat

Lethbridge
Lethbridge ( ) is a city in the province of Alberta, Canada. With a population of 101,482 in its 2019 municipal census, Lethbridge became the fourth Alberta city to surpass 100,000 people. The nearby Canadian Rocky Mountains contribute to the city's warm summers, mild winters, and windy climate. Lethbridge lies southeast of Calgary on the Oldman River. Lethbridge is the commercial, financial, transportation and industrial centre of southern Alberta. The city's economy developed from drift mining for coal in the late 19th century and agriculture in the early 20th century. Half of the workforce is employed in the health, education, retail and hospitality sectors, and the top five employers are government-based. The only university in Alberta south of Calgary is in Lethbridge, and two of the three colleges in southern Alberta have campuses in the city. Cultural venues in the city include performing art theatres, museums and sports centres. History Before the 19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow River
The Bow River is a river in Alberta, Canada. It begins within the Canadian Rocky Mountains and winds through the Alberta foothills onto the prairies, where it meets the Oldman River, the two then forming the South Saskatchewan River. These waters ultimately flow through the Nelson River into Hudson Bay. The Bow River runs through the city of Calgary, taking in the Elbow River at the historic site of Fort Calgary near downtown. The Bow River pathway, developed along the river's banks, is considered a part of Calgary's self-image. First Nations made varied use of the river for sustenance before settlers of European origin arrived, such as using its valleys in the buffalo hunt. The name ''Bow ''refers to the reeds that grew along its banks and were used by the First Nations to make bows; the Blackfoot language name for the river is , meaning "river where bow reeds grow". The river is an important source of water for irrigation and drinking water. Between the years 1910 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldman River
The Oldman River is a river in southern Alberta, Canada. It flows roughly west to east from the Rocky Mountains, through the communities of Fort Macleod, Lethbridge, and on to Grassy Lake, where it joins the Bow River to form the South Saskatchewan River, which eventually drains into the Hudson Bay. Oldman River has a total length of and a drainage area of . History The Oldman River was, at one time, known as the Belly River. The Belly River is now a separate river that is a tributary of the Oldman. In 1991, the Alberta government finished construction of the Oldman River Dam. The Piikani renegade, led by Milton Born With A Tooth, had attempted to divert the Oldman River away from the Lethbridge Northern Irrigation District canal intake, leading to an armed standoff. The dam was constructed where the Oldman, Crowsnest, and Castle river systems converge. 2013 floods On June 21, 2013, during the 2013 Alberta floods Alberta experienced heavy rainfall that triggered catastrop ...

Petroleum Reservoir
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Petroleum reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs, the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods. Oil field An oil field is an area of accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, ...

Shales
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding p ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
