Kaskapau Formation
The Kaskapau Formation is a geological formation in North America whose strata date back to the Late Cretaceous. The name derives from ''kaskapahtew'' (ᑲᐢᑲᐸᐦᑌᐤ), the Cree word for "smoky". It was first described on the banks of the Smoky River, close to the confluence with the Puskwaskau River by F.H. McLearn in 1926. Geographical distribution The formation is thick in the Peace River and Smoky River area, and thickens up to in the foothills of the Northern Rocky Mountains in British Columbia. It is exposed along the Peace River near Dunvegan, as well as in the Smoky River area. The formation is part of the Smoky River Group, and is conformably overlain by the Bad Heart Formation in the western area, and unconformably by the Cardium Formation in the Pouce Coupe River area. It is conformable underlain by the Dunvegan Formation. The Kaskapau Formation is equivalent to the Colorado Group shale in central Alberta. It is equivalent to the upper Blackstone Formati ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Alberta
Central Alberta is a region located in the Canadian province of Alberta. Central Alberta is the most densely populated rural area in the province. Agriculture and energy are important to the area's economy.

Colorado Group
Colorado is a geologic name applied to certain rocks of Cretaceous age in the North America, particularly in the western Great Plains. This name was originally applied to classify a group of specific marine formations of shale and chalk known for their importance in Eastern Colorado. The surface outcrop of this group produces distinctive landforms bordering the Great Plains and it is a significant feature of the subsurface of the Denver Basin and the Western Canadian Sedimentary Basin. These formations record important sequences of the Western Interior Seaway, and as the geology of this seaway was studied, this name came to be used in states beyond Colorado, but was later replaced in several of these states with more localized names. The USGS convention has been to use Colorado Group where the rocks are further divided into formations, Colorado Formation where no beds are developed enough to be mapped as formations, and Colorado Shale where the unit is composed of little ...

Pouce Coupe River
The Pouce Coupe River is a major tributary of the Peace River (Canada), Peace River in Alberta and British Columbia, Canada. Its name is officially spelled ''Pouce Coupé River'', but it is commonly written without the acute accent. Originating in Alberta's Saddle Hills County, it flows into British Columbia's Peace River Regional District, British Columbia, Peace River Regional District, then returns in Alberta in Saddle Hill County, where it empties into the Peace River. The region of Pouce Coupe Prairie, from which the river and village of Pouce Coupe, British Columbia, Pouce Coupe take their names, was called that for a Dunneza, Beaver Indian Chief named 'Pouscapee'. The first European settler in the region was Hector Tremblay, who built a cabin there in 1898. Tremblay, of French people, French origin, translated 'Pouskapee's Prairie' into the nearest French words of similar sound (, meaning "cut thumb" or "cut-off thumb"). Course The Pouce Coupe originates in a small lake i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unconformity
An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. In general, the older layer was exposed to erosion for an interval of time before deposition of the younger layer, but the term is used to describe any break in the sedimentary geologic record. The significance of angular unconformity (see below) was shown by James Hutton, who found examples of Hutton's Unconformity at Jedburgh in 1787 and at Siccar Point in 1788. The rocks above an unconformity are younger than the rocks beneath (unless the sequence has been overturned). An unconformity represents time during which no sediments were preserved in a region or were subsequently eroded before the next deposition. The local record for that time interval is missing and geologists must use other clues to discover that part of the geologic history of that area. The interval of geologic time not represented ...

Northern Rocky Mountains
The Northern Rocky Mountains, usually referred to as the Northern Rockies, are a subdivision of the Canadian Rockies comprising the northern half of the Canadian segment of the Rocky Mountains. While their northward limit is easily defined as the Liard River, which is the northward terminus of the whole Rockies, the southward limit is debatable, although the area of Mount Ovington and Monkman Pass is mentioned in some sources, as south from there are the Continental Ranges, which are the main spine of the Rockies forming the boundary between British Columbia and Alberta.''Landforms of British Columbia'', S. Holland, BC Govt, Bulletin 50, reprinted 1976. Some use the term to mean only the area north of the Peace Arm of the Williston Reservoir, and in reference to Northern Rocky Mountains Provincial Park, while others consider the term to extend all the way south, beyond the limit of the Hart Ranges at Mount Ovington, to include the McBride area, the Sir Alexander Group and Mo ...

Peace River (Canada)
The Peace River (french: links=no, rivière de la Paix) is a river in Canada that originates in the Rocky Mountains of northern British Columbia and flows to the northeast through northern Alberta. The Peace River joins the Athabasca River in the Peace-Athabasca Delta to form the Slave River, a tributary of the Mackenzie River. The Finlay River, the main headwater of the Peace River, is regarded as the ultimate source of the Mackenzie River. The combined Finlay–Peace–Slave–Mackenzie river system is the 13th longest river system in the world. History The regions along the river are the traditional home of the Danezaa people, called the Beaver by the Europeans. The fur trader Peter Pond is believed to have visited the river in 1785. In 1788 Charles Boyer of the North West Company established a fur trading post at the river's junction with the Boyer River. In 1792 and 1793, the explorer Alexander Mackenzie travelled up the river to the Continental Divide. Mackenzie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey. ...
