Greensand Ridge
The Greensand Ridge, also known as the Wealden Greensand, is an extensive, prominent, often wooded, mixed greensand/sandstone escarpment in south-east England. Forming part of the Weald, a former dense forest in Sussex, Surrey and Kent, it runs to and from the East Sussex coast, wrapping around the High Weald and Low Weald. It reaches its highest elevation, , at Leith Hill in Surrey—the second highest point in south-east England, while another hill in its range, Blackdown, is the highest point in Sussex at . The eastern end of the ridge forms the northern boundary of Romney Marsh. About 51 per cent of the Wealden Greensand is protected as the South Downs National Park, Kent Downs Area of Outstanding Natural Beauty and Surrey Hills Area of Outstanding Natural Beauty. Geology and soils Geological history The Greensand Ridge, formed of Lower Greensand, much of which is sandstone and where hardest is locally termed Bargate stone, is a remnant of the Weald dome, ...

Bargate Stone
__NOTOC__ Bargate stone is a highly durable form of sandstone. It owes its yellow, butter or honey colouring to a high iron content. In some contexts it may be considered to be a form of ironstone. However, in the context of stone buildings local to the extraction of Bargate Stone, the term 'ironstone' is often used to refer to a darker stone, also extracted from the Greensand, which rusts to a brown colour. Sources This stone was quarried for centuries in the Bargate Member of the Greensand Ridge, particularly where it is widest in south west Surrey, England. It occurs near the surface and was quarried in the hillsides near Godalming. Medieval quarries are still visible in Godalming, at the foot of Holloway Hill. Bargate stone is rare in current use due to its short supply. Bath stone, Yorkstone and other similar coloured stone is sometimes used as alternatives, or to complement it. Petrography Bargate stone is typically a mix of sandy bioclastic limestone and bioclastic sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Downs
The South Downs are a range of chalk hills in the south-eastern coastal counties of England 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 national park is the UK's most visited, attracting an estimated 39 million visitor-days annually. 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 ...

Blackdown, West Sussex
Blackdown, or Black Down, summit elevation AMSL, is the highest point in both the historic county of Sussex and the South Downs National Park. It is one of the highest points in the south east of England, exceeded by Walbury Hill, Leith Hill and Pilot Hill. Blackdown is protected as part of the South Downs National Park. Location Blackdown is in the far northwest of West Sussex. The hill presents as a dark-sided mass that towers over the western parts of the Low Weald and south-west Surrey. There is no village or hamlet on Blackdown although it lies approximately equidistant from the railway town of Haslemere to the northwest, Fernhurst to the southwest, and Lurgashall to the southeast.Ordnance Survey There are three National Trust car parks on Tennyson's Lane, which runs up Haste Hill from Haslemere. There are numerous footpaths from the surrounding villages, including a steep walk up the southern escarpment from Lurgashall. Blackdown is crossed by the Sussex Border ...

North Downs
The North Downs are a ridge of chalk hills in south east England that stretch from Farnham in Surrey to the White Cliffs of Dover in Kent. Much of the North Downs comprises two Area of Outstanding Natural Beauty, Areas of Outstanding Natural Beauty (AONBs): the Surrey Hills AONB, Surrey Hills and the Kent Downs AONB, Kent Downs. The North Downs Way National Trail runs along the North Downs from Farnham to Dover. The highest point in the North Downs is Botley Hill, Surrey ( above sea level). The ''County Top'' of Kent is Betsom's Hill ( above sea level), which is less than 1 km from Westerham Heights, Bromley, the highest point in Greater London at an elevation of . Etymology 'Downs' is from Old English ''dun'', meaning, amongst other things, "hill". The word acquired the sense of "elevated rolling grassland" around the 14th century. The name contains "North" to distinguish them from a similar range of hills – the South Downs – which runs roughly parallel to them but s ...

Hastings Beds
The Wealden Group, occasionally also referred to as the Wealden Supergroup, is a group (a sequence of rock strata) in the lithostratigraphy of southern England. The Wealden group consists of paralic to continental (freshwater) facies sedimentary rocks of Berriasian to Aptian age and thus forms part of the English Lower Cretaceous. It is composed of alternating sands and clays. The sandy units were deposited in a flood plain of braided rivers, the clays mostly in a lagoonal coastal plain.Jackson (2008) The Wealden Group can be found in almost all Early Cretaceous basins of England: its outcrops curve from the Wessex Basin in the south to the Cleveland Basin in the northeast. It is not found in northwest England and Wales, areas which were at the time tectonic highs where no deposition took place. The same is true for the London Platform around London and Essex. Offshore, the Wealden Group can reach a thickness of 700 metres. The terms ''Wealden'' and ''Wealden facies'' are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weald Clay
Weald Clay or the Weald Clay Formation is a Lower Cretaceous sedimentary rock unit underlying areas of South East England, between the North and South Downs, in an area called the Weald Basin. It is the uppermost unit of the Wealden Group of rocks within the Weald Basin, and the upper portion of the unit is equivalent in age to the exposed portion of the Wessex Formation on the Isle of Wight. It predominantly consists of thinly bedded mudstone. The un-weathered form is blue/grey, and the yellow/orange is the weathered form, it is used in brickmaking. The formation was deposited in lagoonal, lacustrine and alluvial conditions that varied from freshwater to brackish. The climate at the time of deposition is thought to have been semi-arid, and prone to fire. The clay alternates with other subordinate lithologies, notably hard red-weathering beds of ironstone, limestone ( Sussex Marble) and sandstones, notably including the calcareous sandstone unit referred to as the Horsha ...

Gault Clay
The Gault Formation is a geological formation of stiff blue clay deposited in a calm, fairly deep-water marine environment during the Lower Cretaceous Period (Upper and Middle Albian). It is well exposed in the coastal cliffs at Copt Point in Folkestone, Kent, England, where it overlays the Lower Greensand formation, and underlies the Upper Greensand Formation. These represent different facies, with the sandier parts probably being deposited close to the shore and the clay in quieter water further from the source of sediment; both are believed to be shallow-water deposits. The etymology of the name is uncertain and probably of local origin. Distribution It is found in exposure on the south side of the North Downs and the north side of the South Downs. It is also to be found beneath the scarp of the Berkshire Downs, in the Vale of White Horse, in Oxfordshire, England, and on the Isle of Wight where it is known as Blue Slipper. Gault underlies the chalk beneath the London B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Greensand
Greensand or green sand is a sand or sandstone which has a greenish color. This term is specifically applied to shallow marine sediment that contains noticeable quantities of rounded greenish grains. These grains are called ''glauconies'' and consist of a mixture of mixed-layer clay minerals, such as smectite and glauconite. Greensand is also loosely applied to any glauconitic sediment. Formation Greensand forms in anoxic marine environments that are rich in organic detritus and low in sedimentary input. Having accumulated in marine environments, greensands can be fossil-rich, such as in the late-Cretaceous deposits of New Jersey, United States. Occurrence Important exposures are known from both northern and western Europe, North America, southeastern Brazil and north Africa. Well known and important greensands are the Upper and Lower Greensands of England and occur within Eocene and Cretaceous sedimentary strata underlying the coastal plains of New Jersey and Delaware in th ...

Upper Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent 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, Austral ...
