Stiperstones
The Stiperstones ( cy, Carneddau Teon) is a distinctive hill in the county of Shropshire, England. The quartzite rock of the ridge formed some 480 million years ago. During the last Ice Age Stiperstones lay on the eastern margin of the Welsh ice sheet. The hill itself was not glaciated though glaciers occupied surrounding valleys and it was subject to intense freezing and thawing which shattered the quartzite into a mass of jumbled scree surrounding several residual rocky tors. At above sea level it is the second-highest hill in the county, surpassed only by Brown Clee Hill (). Stiperstones' summit ridge is crowned by several jagged outcrops of rock, which may be seen silhouetted against the sky. Geography The Stiperstones is noted for its tors of quartzite. The principal ones are named as follows, from north-east to south-west: * Shepherd's Rock () * Devil's Chair () * Manstone Rock () * Cranberry Rock () * Nipstone Rock () * The Rock () Manstone Rock is the highest of t ...

Shropshire
Shropshire (; alternatively Salop; abbreviated in print only as Shrops; demonym Salopian ) is a landlocked historic county in the West Midlands region of England. It is bordered by Wales to the west and the English counties of Cheshire to the north, Staffordshire to the east, Worcestershire to the southeast, and Herefordshire to the south. A unitary authority of the same name was created in 2009, taking over from the previous county council and five district councils, now governed by Shropshire Council. The borough of Telford and Wrekin has been a separate unitary authority since 1998, but remains part of the ceremonial county. The county's population and economy is centred on five towns: the county town of Shrewsbury, which is culturally and historically important and close to the centre of the county; Telford, which was founded as a new town in the east which was constructed around a number of older towns, most notably Wellington, Dawley and Madeley, which is today th ...

Shropshire Hills
The Shropshire Hills are a dissected upland area and one of the natural regions of England. They lie wholly within the county of Shropshire and encompass several distinctive and well-known landmarks, such as the Long Mynd, Wenlock Edge, The Wrekin and the Clees. The Shropshire Hills lie south of the county town of Shrewsbury between the Welsh border and Much Wenlock, extending as far south as Ludlow. To the north they are bounded by the Shropshire, Cheshire and Staffordshire Plain, to the east by the Severn Valley and Mid Severn Sandstone Plateau, to the southeast by Knighton and the Teme Valley and to the southwest by the Clun and North West Herefordshire Hills. Environment The Shropshire Hills are listed as Natural Area No. 42 and also as National Character Area 65 by Natural England, the UK Government's advisor on the natural environment. The NCA covers an area of and measure around from west to east and north to south. The dominant pattern of the hills is a series of s ...

Marilyn (hill)
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Republic of Ireland, Ireland by height. Lists of mountains and hills in the British Isles#Marilyns, Marilyns are defined as peaks with a topographic prominence, prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Lists of mountains and hills in the British Isles#Munros, Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,011 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) ''Marilyn Monroe, Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Marilyn was the first of several subsequen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Plynlimon
Pumlumon (historically anglicised in various ways including ''Plynlimon,'' Plinlimon and Plinlimmon) is the highest point of the Cambrian Mountains in Wales (taking a restricted definition of the Cambrian Mountains, excluding Snowdonia, the Berwyns and the Brecon Beacons), and the highest point in Mid Wales. It is a massif that dominates the surrounding countryside and is the highest point (county top) of Ceredigion (both the modern council area, and the historic county, also known as Cardiganshire). The highest point of the massif itself is Pen Pumlumon Fawr, which is above ordnance datum. Its other important peaks are Pen Pumlumon Arwystli, Y Garn, Pen Pumlumon Llygad-bychan and Pumlumon Fach. The longest river in Britain, the River Severn, has its source on the mountain, as do the rivers Wye and Rheidol. Folklore says there is a sleeping giant in Pumlumon. Etymology ''Plynlimon'' is anglicized from the Welsh name ''Pumlumon'', which is thought to mean "five t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontesbury
Pontesbury is a village and civil parish in Shropshire and is approximately eight miles southwest of Shrewsbury. In the 2011 census, the village had a population of 1,873 and the parish had a population of 3,227. The village of Minsterley is just over a mile further southwest. The A488 road runs through the village, on its way from Shrewsbury to Bishop's Castle. The Rea Brook flows close by to the north with the village itself nestling on the northern edge of the Shropshire Hills AONB. Shropshire County Council in their current Place Plan detail the development strategy and refer to Pontesbury and neighbouring Minsterley as towns. Local government The village is the seat of an extensive civil parish, with its own parish council grouped into five wards, representing the village and outlying areas such as the villages and hamlets of Pontesford, Plealey, Asterley, Cruckton, Cruckmeole, Arscott, Lea Cross, Malehurst etc., as well as Habberley (which was previously a civil parish ...

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcaniclastic
Volcaniclastics are geologic materials composed of broken fragments (clasts) of volcanic rock. These encompass all clastic volcanic materials, regardless of what process fragmented the rock, how it was subsequently transported, what environment it was deposited in, or whether nonvolcanic material is mingled with the volcanic clasts. The United States Geological Survey defines volcaniclastics somewhat more narrowly, to include only rock composed of volcanic rock fragments that have been transported some distance from their place of origin. In the broad sense of the term, volcaniclastics includes pyroclastic rocks such as the Bandelier Tuff; cinder cones and other tephra deposits; the basal and capping breccia that characterize ʻaʻā lava flows; and lahars and debris flows of volcanic origin.Vincent 2000, pp.27-28 Volcaniclastics make up more of the volume of many volcanoes than do lava flows. Volcaniclastics may have contributed as much as a third of all sedimentation in the geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Head (geology)
Head describes deposits consisting of fragmented material which, following weathering, have moved downslope through a process of solifluction. The term has been used by British geologists since the middle of the 19th century to describe such material in a range of different settings from flat hilltops to the bottoms of valleys. Areas identified as head include deposits of aeolian origin such as blown sand and loess, slope deposits such as gelifluctates and solifluctates, and recently eroded soil material, called colluvium. With geologists becoming more interested in studying the near-surface environment and its related processes, the term head is becoming obsolete. A related term is 'combe (or coombe) rock', descriptive of a body of chalk and flint fragments contained within a mass of chalky earth typically found on the chalk downland Downland, chalkland, chalk downs or just downs are areas of open chalk hills, such as the North Downs. This term is used to describe the chara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
