Loch Borralan
Loch Borralan is a freshwater loch in the Assynt District of Sutherland in the Highland Council Area, northern Scotland. It's located adjacent to the A837 main road near to the settlements of Aultnacealgach and Ledmore and is from Ullapool and from Lairg. Geography The Loch is just over across and the settlement of Aultnacealgach is located directly on the Loch, there's also the Aultnacealgach Lodge which is also on the Loch but despite the name is on the other side. Finally there's the Alt Motel Located Just Northwest of the other Lodge. Both of these boost the tourism in the area, it's proximity to the A837 makes most people go here instead of the nearby albeit larger Loch Urigill. Flowing into the loch there's the Ault an Loin Duibh and the much smaller Allt nan Cealgach and the Allt na Meine. Flowing Outward there's the Ledmore river which flows towards Loch Veyatie and eventually the Atlantic Ocean. There are also nearby peaks of Bad na Cleithe, Cnoc Gorm and ...

Assynt
Assynt ( gd, Asainn or ) is a sparsely populated area in the south-west of Sutherland, lying north of Ullapool on the west coast of Scotland. Assynt is known for its landscape and its remarkable mountains, which have led to the area, along with neighbouring Coigach, being designated as the Assynt-Coigach National scenic area (Scotland), National Scenic Area, one of 40 such areas in Scotland. The western part of Assynt has many distinctively shaped mountains, including Quinag, Canisp, Suilven and Ben More Assynt, that rise steeply from the surrounding "cnoc and lochan" scenery. These can often appear higher than their actual height would indicate due to their steep sides and the contrast with the moorland from which they rise. Many of the most distinctive peaks such as Suilven were formed during the last Ice age, Ice Age, when they were left exposed above the ice sheet as nunataks, and they now remain as inselbergs of highly eroded Torridonian sandstone sitting on a bedrock of mu ...

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mafic Rock
A mafic mineral or rock is a silicate mineral or igneous rock rich in magnesium and iron. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro. Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar. Mafic materials can also be described as ferromagnesian. History The term ''mafic'' is a portmanteau of "magnesium" and "ferric" and was coined by Charles Whitman Cross, Joseph P. Iddings, :de:Louis V Pirsson, Louis Valentine Pirsson, and Henry Stephens Washington in 1912. Cross' group had previously divided the major rock-forming minerals found in igneous rocks into ''salic'' minerals, such as quartz, feldspars, or feldspathoids, and ''femic'' minerals, such as olivine and pyroxene. However, micas and aluminium-rich amphiboles were excluded, while some calcium minerals containing little iron or magnesium, such as wollastonite or apat ...

Pyroxene
The pyroxenes (commonly abbreviated to ''Px'') are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks. Pyroxenes have the general formula , where X represents calcium (Ca), sodium (Na), iron (Fe II) or magnesium (Mg) and more rarely zinc, manganese or lithium, and Y represents ions of smaller size, such as chromium (Cr), aluminium (Al), magnesium (Mg), cobalt (Co), manganese (Mn), scandium (Sc), titanium Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in ... (Ti), vanadium (V) or even iron (Fe II) or (Fe III). Although aluminium substitutes extensively for silicon in silicates such as feldspars and amphiboles, the substitution occurs only to a limited extent in most pyroxenes. They share a common structure consisting of single chains of si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepheline Syenite
Nepheline syenite is a holocrystalline plutonic rock that consists largely of nepheline and alkali feldspar. The rocks are mostly pale colored, grey or pink, and in general appearance they are not unlike granites, but dark green varieties are also known. Phonolite is the fine-grained extrusive equivalent. Petrology Nepheline syenites are silica-undersaturated and some are peralkaline (terms discussed in igneous rock). Nepheline is a feldspathoid, a solid-solution mineral, that does not coexist with quartz; rather, nepheline would react with quartz to produce alkali feldspar. They are distinguished from ordinary basic syenites not only by the presence of nepheline but also by the occurrence of many other minerals rich in alkalis and in rare earths and other incompatible elements. Alkali feldspar dominates, commonly represented by orthoclase and the exsolved lamellar albite, form perthite. In some rocks the potash feldspar, in others the soda feldspar predominates.

Borolanite
Borolanite is an historical petrological name for a pyroxene-melanite bearing nepheline syenite variety which contains nepheline-alkali feldspar pseudomorphs interpreted to be after leucite which occur as conspicuous white spots in the dark rock matrix. The rock occurs in the Borralan Igneous Complex or Loch Borralan Complex which is an alkalic igneous complex near Loch Borralan in northwest Scotland. The 1911 Britannica described borolanite as: one of the most remarkable rocks of the British Isles, found on the shores of Loch Borolan (Loch Borralan) in Sutherland, after which it has been named. In this locality there is a considerable area of granite rich in red alkali feldspar, and passing, by diminution in the amount of its quartz, into quartz-syenites and syenites. At the margins of the outcrop patches of nepheline syenite occur; usually the nepheline is decomposed, but occasionally it is well-preserved; the other ingredients of the rock are brown garnet (melanite) and aegirin ...

Loch Veyatie
Loch Veyatie (Gaelic: Loch Mheathadaidh) is a large freshwater loch in north-west Scotland. It stretches for 6 km north-westwards from the settlement of Elphin, and lies between Suilven and Cùl Mòr. The loch is located in an area known as the ''Assynt-Coigach National Scenic Area'', one of 40 such areas in Scotland. Parish boundary The boundary between Ross-shire and Sutherland (and therefore between the parishes of Lochbroom and Assynt) runs the length of the loch. Angling Well known for its trout (including ferox) and charr, it is a popular destination for anglers. Run-off from a salmon hatchery at the eastern end of the loch attracts large fish, including, unusually, charr, into its main feeder river, the Abhainn Mhòr. The reservoir Cam Loch is directly located 1 km to the northeast, and follows the same orientation. Geography Loch Veyatie is drained at its western end by Uidh Fheàrna, a channel of slow-moving water leading into Fionn Loch, which is itsel ...
