Shaunavon Formation
The Shaunavon Formation is a stratigraphical unit of Bathonian age in the Western Canadian Sedimentary Basin. It takes the name from the town of Shaunavon, and was first described in the ''Tidewater A.O. Eastend Crown No. 1'' well, drilled south-west of the settlement, by R.L. Milner and G.E. Thomas in 1954.Milner, R.L. and Thomas, G E., 1954. Jurassic System in Saskatchewan. In: Western Canada Sedimentary Basin American Association of Petroleum Geologists, p. 250-267 Lithology The Shaunavon Formation is composed of two members. The lower member consists of buff microcrystalline massive limestone in the lower part with an oolitic bed at the top. The upper member consists of calcareous sandstone and oolitic limestone, shell coquina and argillaceous limestone with interbeds of gray and green shale 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) ...

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 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 Abraham Gottlob Wer ...

Coquina
Coquina () is a sedimentary rock that is composed either wholly or almost entirely of the transported, abraded, and mechanically sorted fragments of the shells of mollusks, trilobites, brachiopods, or other invertebrates. The term ''coquina'' comes from the Spanish word for " cockle" and "shellfish". For a sediment to be considered to be a coquina, the particles composing it should average or greater in size. Coquina can vary in hardness from poorly to moderately cemented. Incompletely consolidated and poorly cemented coquinas are considered grainstones in the Dunham classification system for carbonate sedimentary rocks. A well-cemented coquina is classified as a biosparite (fossiliferous limestone) according to the Folk classification of sedimentary rocks. Coquinas accumulate in high-energy marine and lacustrine environments where currents and waves result in the vigorous winnowing, abrasion, fracturing, and sorting of the shells that compose them. As a result, they typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologic Formations Of Saskatchewan
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes ...

Weyburn, Saskatchewan
Weyburn is the eleventh-largest city in Saskatchewan, Canada. The city has a population of 10,870. It is on the Souris River southeast of the provincial capital of Regina and is north from the North Dakota border in the United States. The name is reputedly a corruption of the Scottish "wee burn," referring to a small creek. The city is surrounded by the Rural Municipality of Weyburn No. 67. History The Canadian Pacific Railway (CPR) reached the future site of Weyburn from Brandon, Manitoba in 1892 and the Soo Line from North Portal on the US border in 1893. A post office opened in 1895 and a land office in 1899 in anticipation of the land rush which soon ensued. In 1899, Knox Presbyterian Church was founded with its building constructed in 1906 in the high-pitched gable roof and arches, standing as a testimony to the faith and optimism in the Weyburn area. Weyburn was legally constituted a village in 1900, a town in 1903 and finally as a city in 1913. From 1910 until 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Williston Basin
The Williston Basin is a large intracratonic sedimentary basin in eastern Montana, western North Dakota, South Dakota, southern Saskatchewan, and south-western Manitoba that is known for its rich deposits of petroleum and potash. The basin is a geologic structural basin but not a topographic depression; it is transected by the Missouri River. The oval-shaped depression extends approximately north-south and east-west. The Williston Basin lies above an ancient Precambrian geologic basement feature, the Trans-Hudson Orogenic Belt that developed in this area about 1.8-1.9 billion years ago, and that created a weak zone that later led to sagging to produce the basin. The Precambrian basement rocks in the center of the basin beneath the city of Williston, North Dakota lie about below the surface. Deposition of sediments began in the Williston area during Cambrian time, but subsidence and basin filling were most intense during the Ordovician, Silurian, and Devonian Periods, when ...
