Lammermuirs
The Lammermuirs are a range of hills in southern Scotland, forming a natural boundary between East Lothian and the Borders. The name "Lammermuir" comes from the Old English ''lambra mōr'', meaning "moorland of the lambs". Geology The Lammermuir Hills are formed from a succession of Silurian and Ordovician age marine sediments known as greywackes together with siltstones, shales and mudstones. They are assigned to the Gala Group. Unconformably overlying these highly faulted and folded strata are outcrops of the early Devonian age Great Conglomerate Formation which forms a part of the Reston Group of Old Red Sandstone rocks. These coarse red-purple conglomerates underlie a band of country in the east between Longformacus and Oldhamstocks and also occur in an isolated outcrop east of Soutra Hill and beneath the Dun Law Wind Farm on the western margin of the hills. The same strata extend down Lauderdale on the western margin of the hills. Numerous dykes of different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berwickshire
Berwickshire ( gd, Siorrachd Bhearaig) is a historic county, registration county and lieutenancy area in south-eastern Scotland, on the English border. Berwickshire County Council existed from 1890 until 1975, when the area became part of the Borders region, with most of the historic county becoming part of the lower-tier Berwickshire district. Berwickshire district was abolished in 1996, when all the districts in the Borders region merged to become the Scottish Borders council area. The county takes its name from Berwick-upon-Tweed, its original county town, which was part of Scotland at the time of the county's formation in the twelfth century, but became part of England in 1482 after several centuries of swapping back and forth between the two kingdoms. After the loss of Berwick, Duns and Greenlaw both served as county town at different periods. The low-lying part of Berwickshire between the Tweed and the Lammermuirs is known as "the Merse", from an old Scots word for a ...

Longformacus
Longformacus ( gd, Longphort Mhacais) is a small village in Berwickshire in the Scottish Borders area of Scotland. It is around north-west of Duns, in the Lammermuir Hills. The Dye Water runs through the village, flowing east towards its confluence with the Whiteadder Water nearby. In the vicinity are traces of an ancient fortification at Runklie or Wrinklaw and the Mutiny Stones cairn. The opera ''Lucia di Lammermoor'', written by Gaetano Donizetti and based on Sir Walter Scott's ''The Bride of Lammermoor'', was set in the Lammermuirs and an old form of the village's name, Lockermachus, is mentioned in Scott's novel. The Southern Upland Way, a Long Distance Route which crosses southern Scotland, passes through the village, and the Sir Walter Scott Way from Moffat to Cockburnspath passes through Longformacus. Etymology Longformacus derives its name from the Gaelic ''Longphort Mhacais'', meaning 'Macas's camp'. Derivation from ''Lann Fothir Maccus'', meaning 'church on the l ...

St Abb's Head
St Abb's Head is a rocky promontory by the village of St Abbs in Scottish Borders, Scotland, and a national nature reserve administered by the National Trust for Scotland. St Abb's Head Lighthouse was designed and built by the brothers David Stevenson and Thomas Stevenson and began service on 24 February 1862. Geology The layered sedimentary rocks of greywacke and siltstone which lie to the north and south of the Head were laid down at the bottom of the sea between 460 and 410 million years ago. The Head itself is made from hard volcanic rock which formed as lava flowed from volcanoes around 400 million years ago. The different type of rocks accounts for the contrast in colour between the rocks of the Head and those of mainland cliffs. The softer sedimentary rocks have eroded over time, leaving behind the high headland made from the harder rock. However even this tough volcanic rock has been affected by the actions of the sea, leaving steep gullies and sea stacks which are ...

Gala Water
The Gala Water ( Lowland Scots: Gala Watter; Scottish Gaelic An Geal Ath) is a river in the Scottish Borders area of Scotland and a tributary of the River Tweed. It is sometimes known as the "Gala", which nickname is also shared with Galashiels, which it flows through. The "Braw Lads O Gala Watter" is a song about people from Galashiels. Etymology The name ''Gala'' may be from the Old English ''galga'' meaning "gallows" ( Scots ''galwe''), perhaps by back-formation from Galashiels. Or else, ''Gala'' may originally be from Brittonic, and derived from ''*gāl'' meaning "enmity, hatred" ( Welsh ''gâl''), or cognate to the Welsh verb ''galw'', "call" ( Cornish ''galow'', "a call"). The river may share an etymology with Gala Lane in Ayrshire, which flows into Loch Doon. Levels At Galashiels the depth of the water is between and , although was as deep at on one occasion in 2002.

Selkirkshire
Selkirkshire or the County of Selkirk ( gd, Siorrachd Shalcraig) is a historic county and registration county of Scotland. It borders Peeblesshire to the west, Midlothian to the north, Roxburghshire to the east, and Dumfriesshire to the south. It derives its name from its county town, the royal burgh of Selkirk. The county was historically also known as Ettrick Forest. Unlike many historic counties, Selkirkshire does not have its own lieutenancy area, but forms part of the Roxburgh, Ettrick and Lauderdale lieutenancy area. History In the 1st Century AD Selkirk formed part of the lands of the native people who hunted it rather than settled there. Neither the Romans, Angles, or the Saxons cleared much of the forestry there and for centuries Selkirk was known for its forest coverage. Indeed, an alternative name for the county was Ettrick Forest. Under the Scottish kings the forest was regarded as Royal. Despite this it was not until the reign of James V that sheriffs were appoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gifford, East Lothian
} Gifford is a village in the parish of Yester in East Lothian, Scotland. It lies approximately south of Haddington and east of Edinburgh. It groups around the Colstoun Water (locally called Gifford Water) at the junction of the B6369 and B6355 surrounded by rural farmland. History The village of Gifford takes its name from the 13th-century Sir Hugo de Giffard of Yester, whose ancient Scoto-Norman family possessed the baronies of Yester, a name that derives from the Cambro-British word Ystrad (modern Welsh: Vale), Morham, and Duncanlaw in Haddingtonshire, and Tayling and Poldame in the counties of Perthshire and Forfar. The first Hugo de Giffard's grandson, Hugh de Giffard, was a noted magician who built Yester Castle ( south-east of the present-day Yester House), the ruins and an underground chamber (the 'Goblin Ha') of which can be seen in Yester Wood. The same ''Hobgoblin Hall'' featured in the poem " Marmion" by Walter Scott. The Mercat Cross was built in 1780 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

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 ...

Lithology
The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples, or with low magnification microscopy. Physical characteristics include colour, texture, grain size, and composition. Lithology may refer to either a detailed description of these characteristics, or a summary of the gross physical character of a rock. Examples of lithologies in the second sense include sandstone, slate, basalt, or limestone. Lithology is the basis of subdividing rock sequences into individual lithostratigraphic units for the purposes of mapping and correlation between areas. In certain applications, such as site investigations, lithology is described using a standard terminology such as in the European geotechnical standard Eurocode 7. Rock type The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed directly from magma, which is a mixture of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dike (geology)
A dike or dyke, in Geology, geological usage, is a sheet of rock that is formed in a Fracture (geology), fracture of a pre-existing rock body. Dikes can be either Intrusive rock, magmatic or Sedimentary rock, sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
