Isle Of Purbeck
The Isle of Purbeck is a peninsula in Dorset, England. It is bordered by water on three sides: the English Channel to the south and east, where steep cliffs fall to the sea; and by the marshy lands of the River Frome and Poole Harbour to the north. Its western boundary is less well defined, with some medieval sources placing it at Flower's Barrow above Worbarrow Bay. John Hutchins, author of ''The History and Antiquities of the County of Dorset'', defined Purbeck's western boundary as the Luckford Lake steam, which runs south from the Frome. According to writer and broadcaster Ralph Wightman, Purbeck "is only an island if you accept the barren heaths between Arish Mell and Wareham as cutting off this corner of Dorset as effectively as the sea." The most southerly point is St Alban's Head (archaically St. Aldhelm's Head). From 1974 to 2019, the whole of the Isle of Purbeck lay within the local government district of Purbeck, which was named after it. The district extended ...

Purbeck Mineral And Mining Museum
The Purbeck Mineral and Mining Museum exists to preserve and interpret the historic extractive industries in ball clay mining in the Isle of Purbeck. The museum is located adjacent to Norden station on the Swanage Railway and is open from the end of March to the end of September on weekends, some weekdays and Bank Holidays. A redundant mine has been relocated to Norden with a railway laid around the site, a new engine shed and the restoration of wagons that worked on the lines around Norden. The main future aim of the museum is to construct a new building at Norden to house ''Secundus'', a 2-foot 8 inch steam loco, wagons and other artefacts not on display at present. It will also contain a library and education centre. It is planned to extend the narrow gauge railway to the other side of the Swanage Branch line to land owned by the group via Bridge 15. In 2010 a structural engineer surveyed Bridge 15, a skew bridge over the Swanage Railway. The condition of the bridge was go ...

Purbeck District
Purbeck was a local government district in Dorset, England. The district was named after the Isle of Purbeck, a peninsula that forms a large proportion of the district's area. However, it extended significantly further north and west than the traditional boundary of the Isle of Purbeck which is the River Frome. The district council was based in the town of Wareham, which is itself north of the Frome. The district was formed under the Local Government Act 1972 on 1 April 1974, from the former municipal borough of Wareham, Swanage urban district and Wareham and Purbeck Rural District. The district and its council were abolished on 1 April 2019, together with the other four districts outside the greater Bournemouth area, to form a new Dorset unitary authority. Its name is recorded in 948 AD as Anglo-Saxon ''Purbicinga'', meaning "of the people of Purbic", where Purbic may be a former Celtic name, or may contain a supposed Anglo-Saxon word *''pur'' or "male lamb".

Purbeck Hills
The Purbeck Hills, also called the Purbeck Ridge or simply the Purbecks, are a ridge of chalk downs in Dorset, England. It is formed by the structure known as the Purbeck Monocline. The ridge extends from Lulworth Cove in the west to Old Harry Rocks in the east, where it meets the sea. The hills are part of a system of chalk downlands in southern England formed from the Chalk Group which also includes Salisbury Plain and the South Downs. For most of their length the chalk of the Purbeck Hills is protected from coastal erosion by a band of resistant Portland limestone. Where this band ends, at Durlston Head, the clay and chalk behind has been eroded, creating Poole Bay and the Solent. The ridge of steeply dipping chalk that forms the Purbeck Hills continues further east on the Isle of Wight. The height of the chalk ridge and proximity to Poole Harbour and the south coast have made the hills of strategic importance. There are a number of Iron Age, Roman and Saxon archaeologi ...

Purbeck Stone
Purbeck stone refers to building stone taken from a series of limestone beds found in the Upper Jurassic to Lower Cretaceous Purbeck Group, found on the Isle of Purbeck, Dorset in southern England. The best known variety of this stone is Purbeck Marble. The stone has been quarried since at least Roman times up to the present day. Geology The Purbeck Group is a sequence of sedimentary rocks that were deposited in a shallow freshwater to brackish lagoonal setting. It ranges in age from Tithonian to Berriasian. Limestone beds are developed at various levels throughout the sequence, each with a different character, which led to them being quarried for specific uses. Towards the top of the Lulworth Formation is the 'New Vein'. In the lower part of the Durlston Formation are the 'Downs vein, 'Freestone Vein' and the 'Laning Vein'. Towards the top of the Durlston are the 'Burr' (or Broken Shell Limestone) with up to three beds of the 'Purbeck Marble' above that. Occurrence The Purbeck Gr ...

Purbeck Marble
Purbeck Marble is a fossiliferous limestone found in the Isle of Purbeck, a peninsula in south-east Dorset, England. It is a variety of Purbeck stone that has been quarried since at least Roman times as a decorative building stone. Geology Stratigraphically these limestone beds lie towards the top of the Durlston Formation of the Purbeck Group. They were deposited during the Berriasian age of the Early Cretaceous epoch. Purbeck Marble is not a metamorphic rock, like a true marble, but is so-called because it can take a fine polish. Its characteristic appearance comes from densely packed shells of the freshwater snail ''Viviparus''. Sussex Marble is similar in type. The 'marble' is properly classified as a biomicrudite, as it consists of large clasts (the snail shells) in a fine-grained limestone mud matrix. The individual marble beds (also known as 'seams'), lie between layers of softer marine clays and mudstone, laid down during repeated marine ingressions. Some of the beds ...

Purbeck Ball Clay
Purbeck Ball Clay is a concentration of ball clay found on the Isle of Purbeck in the English county of Dorset. Geology The main concentration of ball clay in Dorset is to the north of the Purbeck Hills centred on Norden. Ball clays are sedimentary in origin. Approximately 45 million years ago (in the Lutetian stage of the Eocene epoch) the climate was tropical and an ancient River Solent washed kaolinite (formed from decomposed granite) from its parent rock on Dartmoor. As the streams flowed from upland areas they mixed with other clay minerals, sands, gravels, and vegetation before settling in low-lying basins to form overlaying seams of ball clay. Ball clays usually contain three dominant minerals: from 20–80% kaolinite, 10–25% mica, and 6–65% quartz. In addition, there are other 'accessory' minerals and some carbonaceous material (derived from ancient plants) present. Exploitation Purbeck Ball Clay has been used for thousands of years, but large scale commercial extra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
