Ochil Fault
The Ochil Fault is the geological feature which defines the southern edge of the Ochil Hills escarpment in Scotland. North of the fault, Devonian lava flows and pyroclastic deposits slope gently down, thinning towards the north. These are in part overlain by Old Red Sandstone rocks formed later in the Devonian period. Because the deposits thin towards the north, and there are few signs of volcanic necks within the Ochil Hills themselves, it is thought that the eruptive centres were south of the fault, however these are buried deep beneath the Carboniferous rocks including coal measures which are found beneath the low-lying carse lands to the south. To put this in perspective, the prominent hill Dumyat which defines the western extremity of the Ochil Hills has a height of . The nearest colliery, Manor Powis, approximately south of the fault, was approximately the same depth, in carse land that is scarcely above sea level, and was mining coal from Carboniferous strata at least ...

Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Stirling (council Area)
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Scotland
The geology of Scotland is unusually varied for a country of its size, with a large number of differing geological features.Keay & Keay (1994) page 415. There are three main geographical sub-divisions: the Highlands and Islands is a diverse area which lies to the north and west of the Highland Boundary Fault; the Central Lowlands is a rift valley mainly comprising Palaeozoic formations; and the Southern Uplands, which lie south of the Southern Uplands Fault, are largely composed of Silurian deposits. The existing bedrock includes very ancient Archean gneiss, metamorphic beds interspersed with granite intrusions created during the Caledonian mountain building period (the Caledonian orogeny), commercially important coal, oil and iron bearing carboniferous deposits and the remains of substantial Palaeogene volcanoes. During their formation, tectonic movements created climatic conditions ranging from polar to desert to tropical and a resultant diversity of fossil remains. Scotland h ...

Hills Of The Scottish Midland Valley
A hill is a landform that extends above the surrounding terrain. It often has a distinct Summit (topography), summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as Grade (slope), steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stirling
Stirling (; sco, Stirlin; gd, Sruighlea ) is a city in central Scotland, northeast of Glasgow and north-west of Edinburgh. The market town, surrounded by rich farmland, grew up connecting the royal citadel, the medieval old town with its merchants and tradesmen, the Old Bridge and the port. Located on the River Forth, Stirling is the administrative centre for the Stirling council area, and is traditionally the county town of Stirlingshire. Proverbially it is the strategically important "Gateway to the Highlands". It has been said that "Stirling, like a huge brooch clasps Highlands and Lowlands together". Similarly "he who holds Stirling, holds Scotland" is often quoted. Stirling's key position as the lowest bridging point of the River Forth before it broadens towards the Firth of Forth made it a focal point for travel north or south. When Stirling was temporarily under Anglo-Saxon sway, according to a 9th-century legend, it was attacked by Danish invaders. The sound of a ...

Wallace Monument
The National Wallace Monument (generally known as the Wallace Monument) is a 67 metre tower on the shoulder of the Abbey Craig, a hilltop overlooking Stirling in Scotland. It commemorates Sir William Wallace, a 13th- and 14th-century Scottish hero. The tower is open to the public for an admission fee. Visitors approach by foot from the base of the crag on which it stands. On entry there are 246 steps to the final observation platform, with three exhibition rooms within the body of the tower. The tower is not accessible to disabled visitors. Background The tower was constructed following a fundraising campaign, which accompanied a resurgence of Scottish national identity in the 19th century. The campaign was begun in Glasgow in 1851 by Rev Charles Rogers who was joined by William Burns. Burns took sole charge from around 1855 following Rogers' resignation. In addition to public subscription, it was partially funded by contributions from a number of foreign donors, including Ita ...

Fault Line
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Tillicoultry
Tillicoultry ( ; Scottish Gaelic: Tulach Cultraidh, perhaps from older Gaelic ''Tullich-cul-tir'', or "the mount/hill at the back of the country") is a town in Clackmannanshire, Scotland. Tillicoultry is usually referred to as Tilly by the locals. One of the Hillfoots Villages on the A91, which runs from Stirling to St. Andrews, Tillicoultry is situated at the southern base of the Ochil Hills, which provide a spectacular backdrop. The River Devon, Scotland, River Devon lies to the south. The river also runs through neighbouring villages Dollar, Clackmannanshire, Dollar and Alva, Scotland, Alva to the east and west respectively. The former Pit village, mining village of Coalsnaughton lies just south, whilst Alloa lies southwest. The "hill" referred to in the first etymology is likely to be Kirkhill, at the east of the town. The alternative Latin etymology, ''Tellus culta'', the cultivated land, suggested by Rev. William Osborne, minister of the parish from 1773 to 1794, is als ...

Menstrie
Menstrie (Scottish Gaelic: ) is a village in the county of Clackmannanshire in Scotland. It is about east-northeast of Stirling and is one of a string of towns that, because of their location at the foothill base of the Ochil Hills, are collectively referred to as the Hillfoots Villages or simply ''The Hillfoots''. Etymology The name ''Menstrie'', recorded as ''Mestreth'' and ''Mestryn'' in the 1260s, is of Pictish origin. The name is composed of elements cognate to Welsh , meaning 'field, plain', and , 'town, village, farm'. Physical geography Menstrie stands on the carse or flood plain of the River Devon, between 10 and 20 metres altitude above sea level. It is roughly astride the Ochil Fault whose movement gave rise to the dramatic southern scarp of the Ochils but which is now almost quiescent. Two of the most westerly summits of the Ochil Hills, Dumyat and Myreton Hill, rise steeply to the north of the village to reach about 400m altitude. These two hills are divided b ...

The Ochil Fault - Geograph
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Quartz-dolerite
Quartz dolerite or quartz diabase is an intrusive rock similar to dolerite (also called diabase), but with an excess of quartz. Dolerite is similar in composition to basalt, which is volcanic, and gabbro, which is plutonic. The differing crystal sizes are due to the different rate of cooling, basalt cools quickly and has a very fine structure, while gabbro cools very slowly, at great depth, and large crystals develop. Dolerite is intermediate. Quartz dolerite is very common in central Scotland, in intrusive formations, sills and dykes, and is widely quarried for roadstone. It was used with some success for making millstones at one time, the Millstone Grit part of the carboniferous strata not being present in Scotland, but it is no longer used for this purpose, and would probably be illegal now due to the formation of small quartz and other silicate particles, which could cause the serious respiratory disease silicosis Silicosis is a form of occupational lung disease caused b ...
