Biostrome
A reef knoll is a land-based landform that comprises an immense pile of calcareous material that accumulated on a previously existing ancient sea floor. At the time of its accumulation it may have had enough structure from organisms such as sponges to have been free-standing and to withstand the sea currents as material accumulated, and was likely an atoll. Another possibility is the remains of deep water coral. Such structures are thus often fossil-rich. A bioherm is a sedimentary rocky landform enclosed or surrounded by rock of different origin. A biostrome is a distinctly bedded or broadly lenticular sedimentary rocky landform. Krumbein defines these terms as types of stromatolites: "Distinctly bedded, widely extensive, blanketlike build-ups are biostromes. Nodular, biscuit-like, dome-shaped or columnar stromatolites are also referred to as bioherms". England Examples on the Derbyshire/Staffordshire border include Thorpe Cloud and Bunster Hill in southern Dovedale, and also ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parkhouse Hill
Parkhouse Hill is a small but distinctive hill in the Peak District National Park of the Hartington Middle Quarter civil parish, in the English county of Derbyshire. It lies on the north side of the River Dove, close to the border with Staffordshire. Geologically, the hill is the remains of an atoll (a 'reef knoll') which is believed to have existed during the Carboniferous period when what is now the Peak District was covered by a tropical sea. Together with its higher but less distinctive neighbour, Chrome Hill, it forms the Chrome and Parkhouse Hills SSSI, cited for their geology and limestone flora. The walk over Chrome Hill and Parkhouse Hill is known as the Dragon's Back ridge. For many years access to Parkhouse Hill was difficult, as there was no right of way to the summit. Access is now possible under the Countryside and Rights of Way Act 2000, as the hill is a designated access area. A double sunset can sometimes be seen against Parkhouse Hill from nearby Glutton Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Craven Fault System
The Craven Fault System is the name applied by geologists to the group of crustal faults in the Pennines that form the southern edge of the Askrigg Block and which partly bounds the Craven Basin. Sections of the system's component faults which include the North, Middle and South Craven faults and the Feizor FaultBritish Geological Survey 1:50,000 scale geological map (England and Wales) sheet 60 ''Settle'' are evident at the surface in the form of degraded faults scarps where Carboniferous Limestone abuts millstone grit. The fault system is approximately coincident with the southwestern edge of the Yorkshire Dales National Park and the northeastern edge of the Bowland Fells.

Yorkshire Dales
The Yorkshire Dales is an upland area of the Pennines in the Historic counties of England, historic county of Yorkshire, England, most of it in the Yorkshire Dales National Park created in 1954. The Dales comprise river valleys and the hills rising from the Vale of York westwards to the hilltops of the Pennine Drainage divide, watershed. In Ribblesdale, Dentdale and Garsdale, the area extends westwards across the watershed, but most of the valleys drain eastwards to the Vale of York, into the River Ouse, Yorkshire, Ouse and the Humber. The extensive limestone cave systems are a major area for caving in the UK and numerous walking trails run through the hills and dales. Etymology The word ''Dale (landform), dale'', like ''dell'', is derived from the Old English word ''dæl''. It has cognates in the North Germanic languages, Nordic/Germanic languages, Germanic words for valley (''dal'', ''tal''), and occurs in valley names across Yorkshire and Northern England.

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...
