Tranearth Group
The Tranearth Group is a Silurian lithostratigraphy, lithostratigraphic group (stratigraphy), group (a sequence of rock strata) in the southern Lake District and Howgill Fells of the Pennines of northern England. The name is derived from the locality of Tranearth near Torver in Cumbria. The Group is included within the Windermere Supergroup. It comprises laminated hemipelagites and siltstones and some sandstones and limestone which achieve a thickness of between 500 and 1000m. It is divided into a lower Brathay Formation which is overlain by the Birk Riggs Formation (not present in the Howgills) and then by an upper Coldwell Formation. References

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 same vast ...

Lithostratigraphy
Lithostratigraphy is a sub-discipline of stratigraphy, the geological science associated with the study of strata or rock layers. Major focuses include geochronology, comparative geology, and petrology. In general, strata are primarily igneous or sedimentary relating to how the rock was formed. Sedimentary layers are laid down by deposition of sediment associated with weathering processes, decaying organic matter (biogenic) or through chemical precipitation. These layers are often distinguishable as having many fossils and are important for the study of biostratigraphy. Igneous layers occur as stacks of lava flows, layers of lava fragments (called tephra) both erupted onto the Earth's surface by volcanoes, and in layered intrusions formed deep underground. Igneous layers are generally devoid of fossils and represent magmatic or volcanic activity that occurred during the geologic history of an area. There are a number of principles that are used to explain the appearance of ...

Silurian System Of Europe
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone durin ...

Cumbria
Cumbria ( ) is a ceremonial and non-metropolitan county in North West England, bordering Scotland. The county and Cumbria County Council, its local government, came into existence in 1974 after the passage of the Local Government Act 1972. Cumbria's county town is Carlisle, in the north of the county. Other major settlements include Barrow-in-Furness, Kendal, Whitehaven and Workington. The administrative county of Cumbria consists of six districts ( Allerdale, Barrow-in-Furness, Carlisle, Copeland, Eden and South Lakeland) and, in 2019, had a population of 500,012. Cumbria is one of the most sparsely populated counties in England, with 73.4 people per km2 (190/sq mi). On 1 April 2023, the administrative county of Cumbria will be abolished and replaced with two new unitary authorities: Westmorland and Furness (Barrow-in-Furness, Eden, South Lakeland) and Cumberland ( Allerdale, Carlisle, Copeland). Cumbria is the third largest ceremonial county in England by area. It i ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ...

Pennines
The Pennines (), also known as the Pennine Chain or Pennine Hills, are a range of uplands running between three regions of Northern England: North West England on the west, North East England and Yorkshire and the Humber on the east. Commonly described as the "backbone of England", the range stretches northwards from the Peak District at the southern end, through the South Pennines, Yorkshire Dales and North Pennines to the Tyne Gap, which separates the range from the Border Moors and Cheviot Hills across the Anglo-Scottish border, although some definitions include them. South of the Aire Gap is a western spur into east Lancashire, comprising the Rossendale Fells, West Pennine Moors and the Bowland Fells in North Lancashire. The Howgill Fells and Orton Fells in Cumbria are sometimes considered to be Pennine spurs to the west of the range. The Pennines are an important water catchment area with numerous reservoirs in the head streams of the river valleys. The North Pennin ...

Lake District
The Lake District, also known as the Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes, forests, and mountains (or ''fells''), and its associations with William Wordsworth and other Lake Poets and also with Beatrix Potter and John Ruskin. The Lake District National Park was established in 1951 and covers an area of . It was designated a UNESCO World Heritage Site in 2017. The Lake District is today completely within Cumbria, a county and administrative unit created in 1974 by the Local Government Act 1972. However, it was historically divided between three English counties ( Cumberland, Westmorland and Lancashire), sometimes referred to as the Lakes Counties. The three counties met at the Three Shire Stone on Wrynose Pass in the southern fells west of Ambleside. All the land in England higher than above sea level lies within the National Park, including Scafell Pike, the highest mountain in England. ...

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.

Stockdale Group
The Stockdale Group is a Silurian lithostratigraphic group (a sequence of rock strata) in the southern Lake District and Howgill Fells of the Pennines of northern England. The name is derived from the locality of Stockdale near the top of Longsleddale in Cumbria. It is included within the Windermere Supergroup. The rocks of the Group have also previously been referred to as the Stockdale Shales or Stockdale Subgroup. The group comprises limestones and oolites and some sandstones and 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) and tiny fragments (silt-sized particles) of other minerals, especial ...s which reach a maximum thickness of 120m in the area.
