Leusdon Common
Leusdon Common is a Site of Special Scientific Interest (SSSI) within Dartmoor National Park, Devon, England. It is located 800m north of the village of Poundsgate. Leusdon Common is near but not adjacent another protected area: Holne Woodlands SSSI. Leusdon Common is protected because of the geological features of granite rocks at the site. Geology The granite boulders found at Leusdon Common represent an intrusion of Permo-Caboniferous age. These granite rocks show evidence of migmatization and contain xenoliths A xenolith ("foreign rock") is a rock fragment (country rock) that becomes enveloped in a larger rock during the latter's development and solidification. In geology, the term ''xenolith'' is almost exclusively used to describe inclusions in ign ....{{Cite web , title=Igneous Rocks of South-West England (Geological Conservation Review Series No. 5) {{!

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain, or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland, is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserve (United Kingdom), national nature reserves, Ramsar Convention, Ramsar sites, Special Protection Areas, and Special Area of Conservation, Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their Biology, biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or Physical geography, physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poundsgate
Poundsgate is a small village in Dartmoor, Devon, England, located on the road between Ashburton and Princetown. The postal area of "Poundsgate" is a wide geographical area. There are a few cottages clustered around a popular stopping point for travellers, the Tavistock Inn, which is thought to date back to the 13th century. There are also many farms in and around the village. At one time there was a shop, a post office and a garage. Poundsgate takes its name from the pound situated on the left-hand side of the road just past the last house when travelling toward Princetown. This house was once a smithy, the post office, the telephone exchange and a bakery. Poundsgate is situated in the ecclesiastical parish of Leusdon, the civil parish of Widecombe in the Moor and within the manor of Spitchwick.

Holne Woodlands
Holne Woodlands is a Site of Special Scientific Interest (SSSI) within Dartmoor National Park in Devon, England. It is located between Dartmeet and Ashburton and encompasses part of the valley of the River Dart and part of the valley of the River Webburn. This protected area includes several Dartmoor Tors including Combestone Tor, Sharp Tor, Mel Tor, Hockinston Tor, Aish Tor and Blackadon Tor.

Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dike (geology), dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF diagram, QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permo-Carboniferous
The Permo-Carboniferous is the time period including the latter parts of the Carboniferous and early part of the Permian period. Permo-Carboniferous rocks are in places not differentiated because of the presence of transitional fossils, and also where no conspicuous stratigraphic break is present. Permo-Carboniferous time, about 300 million years ago, was a period of significant glaciation. The widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica and Australia was one of the major pieces of evidence for the theory of continental drift, and led ultimately to the concept of a super-continent, Pangaea. Glacial activity spanned virtually the whole of Carboniferous and Early Permian time.A.G. Smith, 1997 Toward the end of the Carboniferous, around 290 million years ago, Gondwana, the southern part of Pangaea, was located near the south pole. Glacial centres expanded across the continents, producing glacial till ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Migmatite
Migmatite is a composite rock (geology), rock found in medium and high-grade metamorphic environments, commonly within Precambrian craton, cratonic blocks. It consists of two or more constituents often layered repetitively: one layer is an older metamorphic rock that was reconstituted subsequently by partial melting ("paleosome"), while the alternate layer has a Pegmatite, pegmatitic, Aplite, aplitic, Granite, granitic or generally plutonic appearance ("neosome"). Commonly, migmatites occur below deformed metamorphic rocks that represent the base of eroded mountain chains. Migmatites form under extreme temperature and pressure conditions during Metamorphism#Prograde and retrograde, prograde metamorphism, when partial melting occurs in metamorphic paleosome. Components Solid solution, exsolved by partial melting are called neosome (meaning ‘new body’), which may or may not be heterogeneous at the microscopic to macroscopic scale. Migmatites often appear as tightly, incoheren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenolith
A xenolith ("foreign rock") is a rock (geology), rock fragment (Country rock (geology), country rock) that becomes enveloped in a larger rock during the latter's development and solidification. In geology, the term ''xenolith'' is almost exclusively used to describe inclusion (mineral), inclusions in igneous rock entrained during magma ascent, emplacement and eruption. Xenoliths may be engulfed along the margins of a magma chamber, torn loose from the walls of an erupting lava conduit or explosive diatreme or picked up along the base of a flowing body of lava on the Earth's surface. A xenocryst is an individual foreign crystal included within an igneous body. Examples of xenocrysts are quartz crystals in a silica-deficient lava and diamonds within kimberlite diatremes. Xenoliths can be non-uniform within individual locations, even in areas which are spatially limited, e.g. rhyolite-dominated lava of Nii-jima, Niijima volcano (Japan) contains two types of gabbroic xenoliths which a ...

Protected Areas Of Devon
Protection is any measure taken to guard something against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...
