Cockercombe Tuff
Cockercombe Tuff is a greenish-grey, hard pyroclastic rock, formed by the compression of volcanic ash containing high quantities of chlorite, which gives it its distinctive colour. It is found almost exclusively in the south-eastern end of the Quantock Hills near Cockercombe, Somerset, England from where it has been quarried for centuries. Quantock Lodge Quantock Lodge is a grade II listed nineteenth-century Gothic revival mansion built by Henry Labouchere, 1st Baron Taunton (1798–1869), to the design of Henry Clutton. It is built from Cockercombe tuff and is located near Aley in the parish of ... is built from Cockercombe tuff.

Pyroclastic Rock
Pyroclastic rocks (derived from the el, πῦρ, links=no, meaning fire; and , meaning broken) are clastic rocks composed of rock fragments produced and ejected by explosive volcanic eruptions. The individual rock fragments are known as pyroclasts. Pyroclastic rocks are a type of volcaniclastic deposit, which are deposits made predominantly of volcanic particles. 'Phreatic' pyroclastic deposits are a variety of pyroclastic rock that forms from volcanic steam explosions and they are entirely made of accidental clasts. 'Phreatomagmatic' pyroclastic deposits are formed from explosive interaction of magma with groundwater. Unconsolidated accumulations of pyroclasts are described as tephra. Tephra may become lithified to a pyroclastic rock by cementation or chemical reactions as the result of the passage of hot gases (fumarolic alteration) or groundwater (e.g. hydrothermal alteration and diagenesis) and burial, or, if it is emplaced at temperatures so hot that the soft glassy pyrocl ...

Volcanic Ash
Volcanic ash consists of fragments of rock, mineral crystals, and volcanic glass, created during volcano, volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter. The term volcanic ash is also often loosely used to refer to all explosive eruption products (correctly referred to as ''tephra''), including particles larger than 2 mm. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. The force of the gases shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass. Ash is also produced when magma comes into contact with water during phreatomagmatic eruptions, causing the water to explosively flash to steam leading to shattering of magma. Once in the air, ash is transported by wind up to thousands of kilometres away. Due to its wide dispersal, ash can have a number of impacts on society, including animal a ...

Chlorite Group
The chlorites are the group of phyllosilicate minerals common in low-grade metamorphic rocks and in altered igneous rocks. Greenschist, formed by metamorphism of basalt or other low-silica volcanic rock, typically contains significant amounts of chlorite. Chlorite minerals show a wide variety of compositions, in which magnesium, iron, aluminium, and silicon substitute for each other in the crystal structure. A complete solid solution series exists between the two most common end members, magnesium-rich clinochlore and iron-rich chamosite. In addition, manganese, zinc, lithium, and calcium species are known. The great range in composition results in considerable variation in physical, optical, and X-ray properties. Similarly, the range of chemical composition allows chlorite group minerals to exist over a wide range of temperature and pressure conditions. For this reason chlorite minerals are ubiquitous minerals within low and medium temperature metamorphic rocks, some igneous r ...

Quantock Hills
The Quantock Hills west of Bridgwater in Somerset, England, consist of heathland, oak woodlands, ancient parklands and agricultural land. They were England's first Area of Outstanding Natural Beauty, designated in 1956. Natural England have designated the Quantock Hills as a national character area. They are entirely surrounded by another: the Vale of Taunton and Quantock Fringes. The hills run from the Vale of Taunton Deane in the south, for about to the north-west, ending at Kilve and West Quantoxhead on the coast of the Bristol Channel. They form the western border of Sedgemoor and the Somerset Levels. From the top of the hills on a clear day, it is possible to see Glastonbury Tor and the Mendips to the east, Wales as far as the Gower Peninsula to the north, the Brendon Hills and Exmoor to the west, and the Blackdown Hills to the south. The highest point on the Quantocks is Wills Neck, at . Soil types and weather combine to support the hills' plants and animals. In 1970, an ...

Quantock Lodge
Quantock Lodge is a grade II listed nineteenth-century Gothic revival mansion built by Henry Labouchere, 1st Baron Taunton (1798–1869), to the design of Henry Clutton. It is built from Cockercombe tuff and is located near Aley in the parish of Over Stowey in Somerset. It has variously been used as an estate, a sanatorium and a school. History ] The Estate In 1833, Henry Labouchere, 1st Baron Taunton, Lord Taunton purchased the estates of Over Stowey from the Earl of Egmont, and added the estates of Nether Stowey in 1838, forming the estate of 'Over and Nether Stowey' or just the 'Quantock' estate, named after the nearby Quantock Hills. Lord Taunton was then the MP for nearby Taunton, and had been born in Over Stowey; he was later to become President of the Board of Trade, Chief Secretary for Ireland and Secretary of State for the Colonies, before his resignation from the House of Commons and his ennoblement as Baron Taunton in 1859.

Volcanic Rocks
Volcanic rock (often shortened to volcanics in scientific contexts) is a Rock (geology), rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of Volcano, volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into Subvolcanic rock, hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield (geology), shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate bound ...

Building Stone
Building material is material used for construction. Many naturally occurring substances, such as clay, rock (geology), rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, Building insulation, insulation, plumbing, and roofing material, roofing work. They provide the make-up of :Human habitats, habitats and architecture, structures including homes. The total cost of building materials In history, there are trends in building materials from being natural to becoming more man-made and Composite material, composite; biodegradable to imperishable; indigenous (local) to being transported globally; repairable to disposable; chosen for increased levels of ...

Geology Of Somerset
Somerset is a rural county in the southwest of England, covering . It is bounded on the north-west by the Bristol Channel, on the north by Bristol and Gloucestershire, on the north-east by Wiltshire, on the south-east by Dorset, and on the south west and west by Devon. It has broad central plains with several ranges of low hills. The landscape divides into four main geological sections from the Silurian through the Devonian and Carboniferous to the Permian which influence the landscape, together with water-related features. The low-lying areas of the North Somerset Levels and Somerset Levels have been subject to thousands of years of flooding and man's attempts to control the flow of water. In the north of the county the Limestone of the Mendip Hills dominates the landscape, while in the south the Blackdown and Quantock Hills rise out of the levels. The highest areas are on Exmoor. The wide variety of landscapes has led to several areas being designated as Sites of Special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
