Ravenscar Group
The Ravenscar Group is a Jurassic lithostratigraphic group (a sequence of rock strata) which occurs within the Cleveland Basin of North Yorkshire and extends to both the Hambleton and Howardian Hills. The name is derived from Ravenscar on the North Yorkshire coast where rocks of this age occur. It was earlier known as the 'Middle Jurassic Series'.British Geological Survey 1:50,000 scale geological map sheet (England and Wales series) no 34 ''Guisborough'' It is the stratigraphic equivalent to the Inferior Oolite Group and most of the Great Oolite Group, being overlain by the Cornbrash Formation The Cornbrash Formation is a Middle Jurassic geological formation in England.

Ravenscar, North Yorkshire
Ravenscar is a coastal village in the Scarborough district of North Yorkshire, England. It is within the civil parish of Staintondale and the North York Moors National Park, and is north of Scarborough. A National Trail, the Cleveland Way, passes through Ravenscar, which is also the eastern terminus of the Lyke Wake Walk. The official end of the walk is at a point where the path meets the coast road. History Ravenscar was the location of a late 4th century Roman signal station, part of a chain that extended along the Yorkshire coast. To the north of the village is the old Peak alum works, now a National Trust site, but once an important part of the dyeing industry. The last alum works at Ravenscar closed down in 1871 after the invention of a synthetic dye fixer. At the edge of the village is a disused windmill, Peak Mill, which dates from 1858. Until the early 20th century Ravenscar was known as 'Peak' or 'The Peak'. At the turn of the 19th–20th century, plans we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aalenian Stage
The Aalenian () is a subdivision of the Middle Jurassic Epoch/Series of the geologic timescale that extends from about 174.1 Ma to about 170.3 Ma (million years ago). It was preceded by the Toarcian and succeeded by the Bajocian. Stratigraphic definitions The Aalenian takes its name from the town of Aalen, some 70 km east of Stuttgart in Germany. The town lies at the northeastern end of the Swabian Jura. The name Aalenian was introduced in scientific literature by Swiss geologist Karl Mayer-Eymar in 1864. The base of the Aalenian is defined as the place in the stratigraphic column where the ammonite genus '' Leioceras'' first appears. The global reference profile (GSSP) is located 500 meters north of the village of Fuentelsaz in the Spanish province of Guadalajara.Cresta ''et al.'' (2001) The top of the Aalenian (the base of the Bajocian) is at the first appearance of ammonite genus ''Hyperlioceras''. In the Tethys domain, the Aalenian contains four ammonite biozo ...

Geologic Formations Of England
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 Eart ...

Great Oolite Group
The Great Oolite Group is a Middle Jurassic stratigraphic unit that outcrops in southern England. It consists of a complex set of marine deposits primarily mudstone and bioclastic ooidal and fine grained limestone, deposited in nearshore to shelf settings. It is exposed at the surface as a variably thick belt extending roughly NE-SW from the coast of Dorset up to the Humber. It is also present at depth in the Weald and Wessex Basins, as well as offshore. Several of the constituent formations, notably the Taynton Limestone Formation and the Forest Marble Formation are notable for their fossil content, including those of dinosaurs and pterosaurs and some of the earliest mammals. Paleofauna * '' Cardiodon rugulosus'' * ''Cetiosaurus oxoniensis'' * '' Eoplophysis vetustus'' (stegosaurid indet) * ''Megalosaurus bucklandii'' * ''Proceratosaurus bradleyi'' * '' Seldsienean megistorhynchus'' See also * List of dinosaur-bearing rock formations This list of dinosaur-bearing rock ...

Inferior Oolite Group
The Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe. It was deposited during the Middle Jurassic.Weishampel, David B; et al. (2004). "Dinosaur distribution (Middle Jurassic, Europe)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 538–541. . The Inferior Oolite Group as more recently defined is a Jurassic lithostratigraphic group (a sequence of rock strata) in southern and eastern England . It has been variously known in the past as the Under Oolite (or Oolyte), the Inferior Oolite, the Inferior Oolite Series and the Redbourne Group. Outcrops The rocks are exposed from Dorset and Somerset eastwards and northwards through the English Midlands to Yorkshire. It is present at depth in the Wessex-Weald Basin, where it reaches its greatest thickness of 120 m.

Howardian Hills
The Howardian Hills are an Area of Outstanding Natural Beauty located between the Yorkshire Wolds, the North York Moors National Park, and the Vale of York. They take their name from the Howard family who still own local lands. Topography The Howardian Hills form 79 square miles of well-wooded undulating countryside between the flat agricultural Vales of Pickering and York. The irregular high ridges of the Howardian Hills are a southern extension of the rocks of the Hambleton Hills in the North York Moors. Jurassic limestone, pastures, and extensive woodland overlook the agricultural plains below. On the eastern edge, the River Derwent cuts through the Hills in the Kirkham Gorge, a deep winding valley formed as an overflow channel from glacial Lake Pickering. Settlement Although there are no towns within the AONB, the market towns of Helmsley and Malton lie just beyond the boundary. From Malton to Hovingham is a line of spring line villages. The majority of older bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hambleton Hills
The Hambleton Hills are a range of hills in North Yorkshire, England. They form the western edge of the North York Moors but are separated from the moors by the valley of the River Rye. They are the eastern boundary of the low-lying Vale of Mowbray which they abut with a precipitous escarpment. They run in a north–south direction for about and merge with the Cleveland Hills in the north and Howardian Hills in the south. The hills are made up of rocks of middle and late Jurassic age with the hard Corallian Limestone forming the cap at the highest points. The highest point is Black Hambleton which rises to 1,308 feet (400 m) at the northern end of the range. Roulston Scar reaches 919 feet (280 m) and Whitestone cliff is 1,063 feet (324 m). The Corallian Limestone also outcrops along the southern edge of the North York Moors forming the Tabular Hills which run from Black Hambleton eastwards to Scarborough, although much broken through by river valleys.

Rock Strata
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and '' lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Group (stratigraphy)
In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology, but all were deposited in the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
