Formation (stratigraphy)
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] |
Ciechocinek Formation
The Ciechocinek Formation (also known as the Gryfice Formation at Suliszewo), formerly known in Germany as the Green Series (German: ''Grüne Serie'') is a Jurassic (lower Toarcian) geologic formation that extends across the Baltic coast, from Grimmen, Germany, to Lithuania, with its major sequence in Poland and a few boreholes in Kaliningrad. It is mostly known by its diverse entomofauna, composed of more than 150 species of different groups of insects, as well its marine vertebrate fossils, including remains of sharks, actinopterygians and marine reptiles, along terrestrial remains of dinosaurs, including the early thyreophoran ''Emausaurus'' and others not yet assigned to a definite genus. Its exposures are mostly derived from active clay mining of a dislocated glacial raft with exposed Upper Pliensbachian to late Toarcian shallow-marine sediments. Starting with coarse and fine sand deposits with concretions, the pure clay of the Ciechocinek Formation, after the falciferum zon ...

Geologic Formations Of Canada
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 of ...

Cattamarra Coal Measures
The Cattamarra Coal Measures is an Early Jurassic geological unit in Western Australia. Description They are part of the Perth Basin, and are a sequence of non-marine, probably fluvial sandstones, shales and silts including bituminous coal, and are up to 300 m thick. The Cattamarra Coal Measures conformably overly the Eneabba Formation. The Cattamarra Coal Measures constitute an unconventional tight gas reservoir. There are well preserved fossil insects from the Jurassic age in the deposit.

Kota Formation
The Kota Formation is a geological formation in India. The precise age of Kota Formation are uncertain, but it dates from the Early to Middle Jurassic, and is split into a Lower Member and Upper Member.Prasad GVR, and Manhas BK. 2007A new docodont mammal from the Jurassic Kota Formation of India Palaeontologia electronica, 10.2: 1-11 The lower member is thought to be Hettangian-Pliensbachian.Weishampel, David B; et al. (2004). "Dinosaur distribution (Early Jurassic, Asia)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 534–535. . While the upper unit is thought to be Toarcian, but may possibly extend into the Aalenian. It conformably overlies the Dharmaram Formation which is Late Triassic to earliest Jurassic and is unconformably overlain by the Early Cretaceous Gangapur Formation. The lower member is approximately 100 m thick while the upper member is 490 m thick. Both subunits primari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kandreho Formation
The Kandreho Formation is an Early Jurassic (middle or late Toarcian) geological formation of the Mahajanga Basin of Madagascar. The marly limestones of the formation were deposited in a subtidal lagoonal environment. The formation overlies the '' Bouleiceras'' and '' Spiriferina'' beds of the early Toarcian and has been correlated to the Marrat Formation of Saudi Arabia. Fossils of the marine crocodylian '' Andrianavoay'' (originally classed as a species of ''Steneosaurus'') as well as bivalves and the ammonite '' Nejdia'' have been found in the formation. at Fossilworks.orgBuffetaut et al., 1981, p.314 The name Kand ...

Mawson Formation
The Mawson Formation is a geological formation in Antarctica, dating to roughly between 182 and 177 million years ago and covering the Toarcian stages of the Jurassic Period in the Mesozoic Era. Vertebrate remains are known from the formation. The ''Mawson Formation'' is the South Victoria Land equivalent of the Karoo Large Igneous Province in South Africa (including the upper Clarens Formation desertic interbeds), as well the Lonco Trapial Formation and the Cañadón Asfalto Formation of Argentina. Geology The thin lacustrine interbeds of the Mawson Formation have received several names in literature, being known as either Carapace Sandstone or Carapace Formation, being a series of Freshwater environments developed during times when the Kirkpatrick Basalt stopped invading the zone. The lava flow deposits of the Kirkpatrick Basalt belong to the Ferrar Large Igneous Province, developed in a linear belt along the Transantarctic Mountains, from the Weddell Sea region to North V ...

Los Molles Formation
The Los Molles Formation is a geologic formation of Early to Middle Jurassic age, located at northern and central part of Neuquén Basin at Mendoza Shelf in Argentina. It is overlain by the Niyeu–Lajas Formation.McIlroy et al., 2005 Description It is the second largest oil and gas formation in the Neuquén Basin after the Vaca Muerta. Los Molles Formation is estimated to have of technically recoverable shale gas and of technically recoverable oil.EIA, 2013 In July 2015, the ''Buenos Aires Herald'' indicated that Pan American Energy and YPF planned to drill 46 shale gas wells in Los Molles over the next four years in their Lindero Atravesado drilling block, at an estimated cost of US$590 million. Fossil content In several outcrops, the Los Molles formation has been the site of paleontological discoveries: the ichthyosaurs '' Chacaicosaurus'' and ''Mollesaurus'', and, in 2017, an ornithischian, '' Isaberrysaura'', discovered with fossilized contents of the gut.Salgado ...
