Chilterns AONB
The Chiltern Hills is a chalk escarpment in England. The area, northwest of London, covers stretching from Goring-on-Thames in the southwest to Hitchin in the northeast - across Oxfordshire, Buckinghamshire, Hertfordshire, and Bedfordshire. The hills are at their widest. In 1965 almost half of the Chiltern Hills was designated as an Area of Outstanding Natural Beauty (AONB). The northwest boundary is clearly defined by the escarpment. The dip slope is by definition more gradual, and merges with the landscape to the southeast. The southwest endpoint is the River Thames. The hills decline slowly in prominence in northeast Bedfordshire.The Changing Landscape of the Chilterns Chilterns AoNB, Accessed 19 February 2012 |
Nettlebed
Nettlebed is a village and civil parish in Oxfordshire in the Chiltern Hills about northwest of Henley-on-Thames and southeast of Wallingford. The parish includes the hamlet of Crocker End, about east of the village. The 2011 Census recorded a parish population of 727. Archaeology It is claimed that in the 17th century a "Palæolithic floor" was found in Nettlebed Common. Mesolithic flint microliths and cores have been found in the parish. History The earliest known records of the name "Nettlebed" are from the 13th century. The '' Inquisitiones post mortem'' record it as ''Netelbedde'' in 1252 and 1276. The name does mean a nettlebed: a place overgrown with nettles. Nettlebed village is on an ancient route through the Chiltern Hills between Henley on Thames and Wallingford, which for centuries was part of a trunk route between London and Oxford. The road between Henley and Wallingford was made into a turnpike in 1736 and ceased to be a turnpike in 1873. It is now classi ...

Shirburn Chalk Field
Shirburn is a village and civil parish about south of Thame in Oxfordshire. It contains the Grade I listed, 14th-century Shirburn Castle, along with its surrounding, Grade II listed park, and a parish church, the oldest part of which is from the Norman period. The parish has a high altitude by county standards. Its eastern part is in the Chiltern Hills Area of Outstanding Natural Beauty. Shirburn, the largest civil parish in the district, is forested to the south. A motorway cuts across one edge. Manor and castle Shirburn is a spring line settlement at the foot of the Chiltern escarpment. The Domesday Book of 1086 records that the manor of Shirburn was divided equally between Robert D'Oyly and his brother in arms Roger d'Ivry. The building of Shirburn Castle was licensed in 1377. It was owned by the Chamberlain family for many generations. Shirburn Castle became a centre of Recusancy throughout the 16th and 17th centuries. The castle was renovated and remodelled in the G ...

Siliciclastic
Siliciclastic (or ''siliclastic'') rocks are clastic noncarbonate sedimentary rocks that are composed primarily of silicate minerals, such as quartz or clay minerals. Siliciclasic rock types include mudrock, sandstone Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) ..., and conglomerate. Siliciclastic sediments are silica-based sediments, lacking carbon compounds, which are formed from pre-existing rocks, by breakage, transportation and redeposition to form sedimentary rock.Oilfield Glossary: siliciclastic sediment.

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vale Of Pickering
The Vale of Pickering is a low-lying flat area of land in North Yorkshire, England. It is drained by the River Derwent. The landscape is rural with scattered villages and small market towns. It has been inhabited continuously from the Mesolithic period. The present economy is largely agricultural with light industry and tourism playing an increasing role. Location and transport The Vale of Pickering is a low-lying plain, orientated in an east–west direction. It is well defined by the Yorkshire Wolds escarpment to the south, the Corallian limestone foothills of the North York Moors to the north, the North Sea coast to the east and the Howardian Hills to the west. The east–west-orientated main roads ( A64 and A170) in the vale follow the shoreline of the glacial lake, which formed in the vale after the last ice age. The main A169 road crosses the vale in a north–south direction, joining the market towns of Malton and Pickering. At the eastern edge of the vale the A165 ...

Yorkshire Wolds
The Yorkshire Wolds are low hills in the counties of the East Riding of Yorkshire and North Yorkshire in north-eastern England. The name also applies to the district in which the hills lie. On the western edge, the Wolds rise to an escarpment which then drops sharply to the Vale of York. The highest point on the escarpment is Bishop Wilton Wold (also known as Garrowby Hill), which is above sea level. To the north, on the other side of the Vale of Pickering, lie the North York Moors, and to the east the hills flatten into the plain of Holderness. The largest town in the Wolds is Driffield, with other places including Pocklington, Thixendale and Kilham, the original 'capital' of the Wolds. The highest village on the Yorkshire Wolds is Fridaythorpe at above sea level. The market town of Beverley lies on the eastern slopes, along with the civil parish of Molescroft.

Lincolnshire Wolds
The Lincolnshire Wolds are a range of low hills in the county of Lincolnshire, England which run roughly parallel with the North Sea coast, from the Humber Estuary in the north-west to the edge of the Lincolnshire Fens in the south-east. They are a designated Area of Outstanding Natural Beauty (AONB), and the highest area of land in eastern England between Yorkshire and Kent.Ordnance Survey maps: Geology The Wolds are formed largely from a series of pure marine limestones formed during the Cretaceous period, known collectively as the Chalk Group. The chalk overlies a series of other sedimentary strata of late Jurassic/early Cretaceous age. The strata dip gently to the east and form a scarp which runs southeast from Barton upon Humber via Caistor before it loses its identity north of Spilsby. To the north of the Humber Gap, the same formations continue as the Yorkshire Wolds. The rock succession in stratigraphic order i.e. youngest/uppermost first, is this: *White Chalk Subgro ...

South Downs
The South Downs are a range of chalk hills that extends for about across the south-eastern coastal counties of England from the Itchen valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate, East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs and includes large parts of the Weald. The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England. The South Downs are relatively less populated compared to South East England as a whole, although there has been large-scale urban encroachment onto the chalk downland by major seaside resorts, including most notably ...

Isle Of Wight
The Isle of Wight ( ) is a county in the English Channel, off the coast of Hampshire, from which it is separated by the Solent. It is the largest and second-most populous island of England. Referred to as 'The Island' by residents, the Isle of Wight has resorts that have been popular holiday destinations since Victorian times. It is known for its mild climate, coastal scenery, and verdant landscape of fields, downland and chines. The island is historically part of Hampshire, and is designated a UNESCO Biosphere Reserve. The island has been home to the poets Algernon Charles Swinburne and Alfred, Lord Tennyson. Queen Victoria built her summer residence and final home, Osborne House at East Cowes, on the Isle. It has a maritime and industrial tradition of boat-building, sail-making, the manufacture of flying boats, hovercraft, and Britain's space rockets. The island hosts annual music festivals, including the Isle of Wight Festival, which in 1970 was the largest rock music ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cranborne Chase
Cranborne Chase () is an area of central southern England, straddling the counties Dorset, Hampshire and Wiltshire. It is part of the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty (AONB). The area is dominated by, and often considered to be synonymous with, a chalk downland plateau. Part of the English Chalk Formation, it is adjacent to Salisbury Plain and the West Wiltshire Downs in the north, and the Dorset Downs to the south west. The highest point is Win Green Down, in Wiltshire, at . Historically a medieval hunting forest, the area is also noted for its Neolithic and Bronze age archaeology and its rural agricultural character. Definitions As an informally defined region, the boundaries of Cranborne Chase vary depending on usage. When defined as the chalk plateau, it is clearly bounded by escarpments which face the valleys of the Blackmore Vale to the west, the Vale of Wardour to the north, and the Hampshire Avon to the east. To the south th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salisbury Plain
Salisbury Plain is a chalk plateau in the south western part of central southern England covering . It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Hampshire. The plain is famous for its rich archaeology, including Stonehenge, one of England's best known landmarks. Large areas are given over to military training and thus the sparsely populated plain is the biggest remaining area of calcareous grassland in northwest Europe. Additionally the plain has arable land, and a few small areas of beech trees and coniferous woodland. Its highest point is Easton Hill. Physical geography The boundaries of Salisbury Plain have never been truly defined, and there is some difference of opinion as to its exact area. The river valleys surrounding it, and other downs and plains beyond them loosely define its boundaries. To the north the scarp of the ...

Chalk Group
The Chalk Group (often just called the Chalk) is the lithostratigraphic unit (a certain number of rock strata) which contains the Upper Cretaceous limestone succession in southern and eastern England. The same or similar rock sequences occur across the wider northwest European chalk 'province'. It is characterised by thick deposits of chalk, a soft porous white limestone, deposited in a marine environment. Chalk is a limestone that consists of coccolith biomicrite. A biomicrite is a limestone composed of fossil debris ("bio") and calcium carbonate mud ("micrite"). Most of the fossil debris in chalk consists of the microscopic plates, which are called coccoliths, of microscopic green algae known as coccolithophores. In addition to the coccoliths, the fossil debris includes a variable, but minor, percentage of the fragments of foraminifera, ostracods and mollusks. The coccolithophores lived in the upper part of the water column. When they died, the microscopic calcium carbonate p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
