Eycott Volcanic Group
The Eycott Volcanic Group is a group of volcanic rock formations of Ordovician age (Llandeilo to Caradoc epochs) named after the locality of Eycott Hill in the English Lake District.British Geological Survey 1997 ''Cockermouth'' England and Wales sheet 23 Solid 1:50,000 Keyworth, Nottingham, BGS The group overlies the Skiddaw Group and is unconformably overlain by a variety of different Devonian and Carboniferous age rocks. This rock sequence has previously been known as the Eycott Group. It consists largely of andesitic lavas and sills with tuffs, breccias and volcaniclastic sandstones. Its main outcrop is in an east-west oriented band of country in the northern part of the Skiddaw range in the northern Lake District stretching from the village of Bothel east to form the hill of Binsey and further east, the more extensive Caldbeck Fells. A smaller outcrop underlies Greystoke Park just to the east of this area and forms Eycott Hill east of Mungrisdale. There is a further inlie ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

Vein (geology)
In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation. Veins are classically thought of as being the ones in the body not the rock veins and arteries planar fractures in rocks, with the crystal growth occurring normal to the walls of the cavity, and the crystal protruding into open space. This certainly is the method for the formation of some veins. However, it is rare in geology for significant open space to remain open in large volumes of rock, especially several kilometers below the surface. Thus, there are two main mechanisms considered likely for the formation of veins: ''open-space filling'' and ''crack-seal growth''. Open space filling Open space filling is the hallmark of epithermal vein systems, such as a stockwork, in greisens or in cert ...

North Pennines
The North Pennines is the northernmost section of the Pennine range of hills which runs north–south through northern England. It lies between Carlisle to the west and Darlington to the east. It is bounded to the north by the Tyne Valley and to the south by the Stainmore Gap. Overview The North Pennines was designated as an Area of Outstanding Natural Beauty (AONB) in 1988 for its moorland scenery, the product of centuries of farming and lead-mining, and is also a UNESCO Global Geopark. At almost , it is the second largest of the 49 AONBs in the United Kingdom. The landscape of the North Pennines AONB is one of open heather moors between deep dales, upland rivers, hay meadows and stone-built villages, some of which contain the legacies of a mining and industrial past. The area has previously been mined and quarried for minerals such as barytes, coal fluorspar, iron, lead, witherite and zinc.

Inliers And Outliers (geology)
An inlier is an area of older rocks surrounded by younger rocks. Inliers are typically formed by the erosion of overlying younger rocks to reveal a limited exposure of the older underlying rocks. Faulting or folding may also contribute to the observed outcrop pattern. A classic example from Great Britain is that of the inlier of folded Ordovician and Silurian rocks at Horton in Ribblesdale in North Yorkshire which are surrounded by the younger flat-lying Carboniferous Limestone. The location has long been visited by geology students and experts. Another example from South Wales is the Usk Inlier in Monmouthshire where Silurian age rocks are upfolded amidst Old Red Sandstone rocks of Devonian age. A similar outcrop pattern which results from movement on a thrust fault followed by erosion may be termed a window. Conversely an outlier is an area of younger rock surrounded by older rocks. An outlier is typically formed when sufficient erosion of surrounding rocks has taken place to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mungrisdale
Mungrisdale is a small village and civil parish in the north east of the English Lake District in Cumbria. It is also the name of the valley in which the village sits. Mungrisdale is a popular starting point for ascents of the nearby hills, such as Bowscale Fell, Bannerdale Crags and Souther Fell. It lies on the River Glenderamackin, a tributary of the Greta. Mungrisdale has no local amenities except for the Grade II* listed St Kentigern's Church built in 1756, a village hall and a pub, the Mill Inn. The civil parish of Mungrisdale is made up of the hamlets of Berrier, Bowscale, Haltcliff Bridge, Heggle Lane, Hutton Roof, Mosedale, Mungrisdale and Murrah. The parish had a population of 284 in 2001, increasing to 297 at the 2011 Census.

Greystoke Castle
Greystoke Castle is in the village of Greystoke west of Penrith in the county of Cumbria in northern England. (). Details In 1069, after the Norman conquest the English landlord Ligulf de Greystoke was re-granted his land and he built a wooden tower surrounded by a pale (or pele). The first stone structure on the site was built in 1129 by Ivo, his grandson. The building grew to become a large pele tower and in the 14th century after William de Greystoke obtained a royal licence to castellate it, the castle was further enlarged. In 1571 the castle was in the ownership of Thomas Howard, 4th Duke of Norfolk and Earl Marshal of England through his marriage into the Dacre family, who had been the previous owners. The Howards were Catholics and Royalists and as a consequence during the Civil War the castle was laid waste by Parliamentarians under General Lambert in 1648. The castle was enlarged and altered in 1789. Then between 1838 and 1848 the castle was re-built to a desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Binsey
Binsey is a hill on the northern edge of the Lake District in Cumbria, England. It is detached from the rest of the Lakeland hills, and thus provides a good spot to look out at the Northern and North Western Fells of the Lake District, as well as the coastal plain and, across the Solway Firth, Scotland. Snaefell on the Isle of Man is also visible on a clear day. It is the northernmost of the Wainwrights. Topography Binsey stands on the otherwise low-level watershed separating the catchments of the Ellen to the north and the Derwent to the south. A slight ridge connects it to Great Cockup in the main massif of the Northern Fells, two miles to the south east. Binsey itself has a rounded form, but somehow manages to impress the eye more than the similar Great Mell Fell and Little Mell Fell. The ‘pudding basin’ shape holds all around Binsey except to the north west where a ridge descends over Whitas Park to a depression containing the remains of a Roman fort. Beyond is St John ...

Sill (geology)
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A ''sill'' is a ''concordant intrusive sheet'', meaning that a sill does not cut across preexisting rock beds. Stacking of sills builds a sill complex . and a large magma chamber at high magma flux. In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding pla ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
