Geology Of Kent
: ''This article describes the geology of the ceremonial county of Kent. It includes the borough of Medway.'' The geology of Kent in southeast England largely consists of a succession of northward dipping late Mesozoic and Cenozoic sedimentary rocks overlain by a suite of unconsolidated deposits of more recent origin. Overview Kent is the south-easternmost county in England. It is bounded on the north by the River Thames and the North Sea, and on the south by the Straits of Dover and the English Channel. The continent of Europe is a mere 21 miles across the Strait. The major geographical features of the county are determined by a series of ridges running from west to east across the county. These ridges are the remains of the Wealden dome, a denuded anticline across Kent, Surrey and Sussex, which was the result of uplifting caused by the Alpine movements between 10-20 million years ago. The dome was formed of an upper layer of Chalk above subsequent layers of Upper Greens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

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 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 Horsham Stone. It has a gradual, conformable contact with the underlying Tunbridge Wells Sand Formation, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sittingbourne
Sittingbourne is an industrial town in Kent, south-east England, from Canterbury and from London, beside the Roman Watling Street, an ancient British trackway used by the Romans and the Anglo-Saxons and next to the Swale, a strip of sea separating mainland Kent from the Isle of Sheppey. The town became prominent after the death of Thomas Becket in 1170, since it provided a convenient resting point on the road from London to Canterbury and Dover. Chatham Main Line links to London Victoria and HS1 to St Pancras International, the journey taking about an hour from Sittingbourne railway station. History Sittingbourne owes its name to a modernised version of an observation on its location. The town's name came from the fact that there is a small stream or "bourne" running underground in part of the town. Hasted writing in the 1790s in his ''History of Kent'' states that: The Kent Hundred Rolls of 1274–5, preserved in the National Archives, record Sittingbourne as Sydingeburn ...

Gravesend, Kent
Gravesend is a town in northwest Kent, England, situated 21 miles (35 km) east-southeast of Charing Cross (central London) on the south bank of the River Thames and opposite Tilbury in Essex. Located in the diocese of Rochester, it is the administrative centre of the Borough of Gravesham. Its geographical situation has given Gravesend strategic importance throughout the maritime and communications history of South East England. A Thames Gateway commuter town, it retains strong links with the River Thames, not least through the Port of London Authority Pilot Station and has witnessed rejuvenation since the advent of High Speed 1 rail services via Gravesend railway station. The station was recently refurbished and now has a new bridge. Toponymy Recorded as Gravesham in the Domesday Book of 1086 when it belonged to Odo, Earl of Kent and Bishop of Bayeux, the half-brother of William the Conqueror, its name probably derives from ''graaf-ham'': the home of the reeve or ...

Dartford
Dartford is the principal town in the Borough of Dartford, Kent, England. It is located south-east of Central London and is situated adjacent to the London Borough of Bexley to its west. To its north, across the Thames estuary, is Thurrock in Essex, which can be reached via the Dartford Crossing. The town centre lies in a valley through which the River Darent flows and where the old road from London to Dover crossed: hence the name, from ''Darent + ford''. Dartford became a market town in medieval times and, although today it is principally a commuter town for Greater London, it has a long history of religious, industrial and cultural importance. It is an important rail hub; the main through-road now by-passes the town itself. Geography Dartford lies within the area known as the London Basin. The low-lying marsh to the north of the town consists of London Clay and the alluvium brought down by the two rivers—the Darent and the Cray—whose confluence is in this area. T ...

New Naturalist
The New Naturalist Library (also known as ''The New Naturalists'') is a series of books published by Collins in the United Kingdom, on a variety of natural history topics relevant to the British Isles. The aim of the series at the start was: "To interest the general reader in the wild life of Britain by recapturing the inquiring spirit of the old naturalists."Guy Mountfort, ''The Hawfinch''. Collins, 1957. An editors' preface to a 1952 monograph says: "An object of the ''New Naturalist'' series is the recognition of the many-sidedness of British natural history, and the encouragement of unusual and original developments of its forgotten or neglected facets." The first volume to appear was E.B. Ford's ''Butterflies'' in 1945. The authors of this series are usually eminent experts, often professional scientists. This gives the series authority, and many are or have been authoritative introductory textbooks on a subject for some years. The books are written in scientific style, but ...
