River Torrent
River Torrent is a river in County Tyrone, Northern Ireland which enters the River Blackwater approximately 4 km (2.5 mi) from Maghery ferry. It previously acted as a source of industrial waterpower. The river runs through the small village of Newmills in East Tyrone, situated three miles north of Dungannon. Donaghmore village is situated adjacent to the River Torrent, formerly known as the Torrent Flow. Geology The Torrent is a long meandering river, which drains the hills to the north-west of Dungannon. The underlying geology is varied and includes basal clastic, carboniferous limestone, coal and Old Red Sandstone. In the upper reaches, the river channel is shallow and narrow with pebble/cobble substrate and sandy banks. Downstream the banks are vegetated with tall grasses and native tree species. There are also fishing weirs. In its lower reaches, the Torrent widens and runs parallel to the Coalisland Canal. Dukart's Canal Dukart's Canal was built to provide tran ...

Bridge In Newmills - Geograph
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dukart's Canal
Dukart's Canal was built to provide transport for coal from the Drumglass Collieries to the Coalisland Canal in County Tyrone, Ulster, Ireland. It opened in 1777, and used three inclined planes, rather than locks, to cope with changes in level. There is little evidence that it was ever used, as the planes could not be made to work properly, and they were dismantled in 1787. History Coal seams were discovered at Drumglass, near Coalisland, in the 1690s, and the Tyrone coalfields were seen as a way to reduce the amount of coal imported to Dublin, then amounting to between 60,000 and 70,000 tons per year. Thomas Knox, an owner of one of the collieries, petitioned the Irish Parliament in 1709, to advocate the cutting of a canal to enable the resource to be transported more easily. The canal would have followed a similar route to the later Newry Canal, but nothing came of the plan, although it was well received. The scheme was revived in 1727, and assessed by the Surveyor-General in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coalisland Canal
Coalisland Canal (sometimes known as The Tyrone Navigation) is a canal in County Tyrone, Northern Ireland. Construction of the canal began in 1733, but progress was slow and it was not officially opened until 1787. The canal was built to reduce the cost of transporting coal from the Tyrone coalfields to Dublin. An extension known as "Dukart's Canal" was built to link the coalfields of Drumglass with the head of navigation at Coalisland. It opened in 1777 but was an engineering failure and closed when the main canal opened. After some difficulties with the infrastructure, traffic slowly increased, reaching its peak in 1931. Traffic then declined rapidly, and the canal was abandoned in 1954. There has recently been some interest in restoring the remains, as most of the channel is still intact, and a group has been formed, which is now part of the Inland Waterways Association of Ireland, to raise public awareness of the canal and investigate options for the future.

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clastic Rock
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus,Essentials of Geology, 3rd Ed, Stephen Marshak, p. G-3 chunks, and smaller grains of rock broken off other rocks by physical weathering.Essentials of Geology, 3rd Ed, Stephen Marshak, p. G-5 Geologists use the term clastic to refer to sedimentary rocks and particles in sediment transport, whether in suspension or as bed load, and in sediment deposits. Sedimentary clastic rocks Clastic sedimentary rocks are rocks composed predominantly of broken pieces or ''clasts'' of older weathered and eroded rocks. Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material (matrix) composition, and texture. The classification factors are often useful in determining a sample's environment of deposition. An example of clastic environment would be a river system in which the full range of grains being transported by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donaghmore, County Tyrone
Donaghmore (pronounced , Irish: ''Domhnach Mór'' (great church)) is a village, townland and civil parish in County Tyrone, Northern Ireland, about five kilometres (3 mi) northwest of Dungannon. In the 2011 Census it had a population of 1,122 people. The village is beside the River Torrent, formerly known as the Torrent Flow. History Etymology The name Donaghmore derives from the Irish words ''Domhnach Mór'', meaning "great church". This however is a shortened form of its original medieval name ''Domhnach Mór Magh Imchlair'' (also spelt ''in Clair''), the "great church in the plain of Imchlair", referring to the territory of the Fir Imchlair in which it lay. It was according to the Tripartite Life of St. Patrick founded by the saint for the Fir Imchlair.

Dungannon
Dungannon () is a town in County Tyrone, Northern Ireland. It is the second-largest town in the county (after Omagh) and had a population of 14,340 at the 2011 Census. The Dungannon and South Tyrone Borough Council had its headquarters in the town, though since 2015 it has been covered by Mid-Ulster District Council. For centuries, it was the 'capital' of the O'Neill dynasty of Tír Eoghain, who dominated most of Ulster and built a castle on the hill. After the O'Neills' defeat in the Nine Years' War, the English founded a plantation town on the site, which grew into what is now Dungannon. Dungannon has won Ulster in Bloom's Best Kept Town Award five times. It currently has the highest percentage of immigrants of any town in Northern Ireland. History For centuries, Dungannon's fortunes were closely tied to that of the O'Neill dynasty which ruled a large part of Ulster until the 17th century. Dungannon was the clan's main stronghold.
