The Granite Industry
Gabbros & Granites Metamorphic changes are not the only evidence of the increased temperatures that affected the Dalradian rocks as the Iapetus Ocean was consumed. Large volumes of magma (molten rock) were injected into the deformed and metamorphosed Dalradian strata as the crustal plates collided. The magma cooled and crystallised to form large bodies (plutons) of igneous rock; different types of magma produced different types of igneous rock, such as granite and gabbro. The granites are closely associated with the Dalradian rocks which had experienced the highest temperature metamorphic changes. In such areas, some of the metamorphic rocks were heated to such a degree that they began to melt, producing magma that coalesced into larger bodies and eventually cooled to form granite. Many examples of this transformation process can be seen in the coastal outcrops south of Aberdeen at Cove. The Aberdeen granite, famously quarried at Rubislaw, is one of the best known of the granite intrusions generated in this way.

Granite forms from the cooling of large magma bodies at depth in the crust, the slow cooling allowing the growth of large and interlocking mineral crystals. Compositionally, granites typically contain 55-75% silica and are commonly pale coloured with medium to coarse grained crystals discernable to the naked eye. The interlocking crystals provide cohesion which adds strength and makes them suitable for polishing without plucking of the grains. Finer grained granites were typically used for structural purposes (e.g. foundations, walling, kerbstones, setts and paving), while coarser grained and porphyritic (i.e. with large crystals usually of feldspar) varieties were valued for ornamental work. The predominance of silica and other relatively stable minerals in granite make it particularly strong and durable.

Peterhead, one of the most important Aberdeenshire granites, was produced as two varieties, known as Red and Blue Peterhead, both exported throughout the UK and abroad during the 19th century. The red variety was better known and used for ornamental construction and monumental work e.g. London, Cambridge (St John's College Chapel pillars) and Liverpool (St George's Hall pillars). Blue Peterhead was used for decorative building and ornamental work, e.g. the base of fountains in Trafalgar Square and the Prince Albert Mausoleum. Peterhead granite is still quarried at Stirlinghill and Longhaven quarries, where it is mostly crushed for aggregate. Kemnay quarry began production in the mid-19th century producing building stone, setts and kerbs, with the best material reserved for polished monumental work. It is a light grey muscovite-biotite granite. Examples include the Queen Victoria Memorial in London, the Forth Railway Bridge and, more recently, as cladding for the new Scottish Parliament.
Aberdeen Journal 1891 Dancing Cairns Quarry 1880 - This is a Derrick Crane, powered by steam. Derrick cranes were designed to lift heavy loads. In this case the crane could lift 15 tonnes. These cranes were designed to turn and lift. The jib, which sticks out and carries the rope or chain with a hook, was raised or lowered like a ships derrick. A real parallelogram of forces diagram. Probably the Dancing Cairns Quarries in Bucksburn. Dancing Cairns Quarry works were close to the Bucksburn Howe. The quarry had been working since the late 18th century, when it was opened by Messrs Snell, Rennie & May. Many stones were hewn from this quarry for Telford's North Pier extension.

As children we used to go and play in and around the Quarry, catching Tadpoles, Frogs, Newts and Sticklebacks. It has now been filled in with City refuse and on the surface today is now a Golf course, which overlooks Dyce Airport. Buildings in Aberdeen. Used in London for kerbs, paving, etc. Composed of quartz, orthoclase, oligoclase, and mica.

Corrinnie
Quarry The Corrennie Quarry at Tillyfourie. Granite building blocks stacked ready for transport. The quarry is still in operation. Corrennie Quarry Granite from Tillyfouries is a medium grained biotite granite with a salmon-red colour making it favoured for decorative use. Examples include the Glasgow City Chambers and the Tay Railway Bridge. The light grey speckled muscovite-biotite granite from the Dancing Cairns quarry has been used in Trafalgar Square, the Thames Embankment and part of London Bridge. Fine-grained dark greyish-blue biotite granite from Dyce Quarry was favoured for the interior of London Banks and exported overseas to Australia (Bank of Australia, Melbourne). Both Kemnay and Corrennie quarries are still active, along with a number of other granite quarries in Aberdeenshire, but their granites are mostly crushed for aggregate and roadstone, although dimension stone can still be obtained. This large, now disused granite quarry, which is situated at the foot of the South flank of Tillyfourie Hill. A single large pit initially, but by then that quarry had been abandoned in favour of new workings higher up on the South face of the Hill. Sculptor's Appraisal of Corrinnie Granite The extensive trade in Granite appears to have originated with the Messrs. Adam, architects, of London, who, having entered into a contract for paving the Metropolis, in 1764, commenced some quarries in the rocks on the sea-coast, near the lands of Torry, and brought the stone, when prepared, to London; but, finding this mode of supply too expensive, they employed the Aberdeen Masons to furnish them with stone, and, in a short time, a very extensive trade was established, not only in paving-stones, but in large blocks of granite for public buildings and works of great magnitude. Many of the largest blocks were sent to Sheerness, for the construction of the docks at that place, and to London, for the erection of bridges over the Thames, and the foundation of the new Houses of Parliament. The granite, which is extremely hard, and of great beauty when polished, has lately been brought into extensive use for chimney-pieces, vases, pedestals, and other ornamental works, by the application of machinery to the purpose of polishing it, by which the expense is reduced to about 1/3rd of that by hand labour. The quantity of granite exported in 1844, exceeded 27,400 tons. Corrinnie Granite was used for the Base and Cornice of Pedestal of the Albert Memorial, 'an exquisite variety of granite from the estate of Captain John Gordon of Cluny Castle.
Image from the mid 1930s of a Sett Maker in front of his Skaithie in Persley Quarry. He was a ‘Cassie’ maker hewing stone setts for the roads from granite with just a hammer and chisel. The ‘lean-to’ or Skaithie in the rear of the image was the only shelter he had in all weathers.
SETT-MAKING
They are used to pave roads and are also
called setts. The word cassie comes from "causeway" which means roadway. Cassies
were made at quarries in Aberdeen and Aberdeenshire. Millions were produced by
skilled sett-makers. Many were sent to London. They sat in small huts called
scathies. These huts could be lifted and turned to keep the mason out of wind
and rain.
There was a need for men who had the skill and patience to reduce huge
blocks of granite into manageable pieces by chipping it with a variety of
hammers, and chisels to produce the required shape and size. In this 1920's
photograph we see a sett maker at Persley

Nigg Quarries John Adam was one of the Adam Brothers responsible for the building of Dumfries House as well as the Adelphi Buildings in London. The firm was also a contractor for Fort George in Inverness. John Adam, though a competent Architect, worked primarily as the firm’s business manager, overseeing contracts, legal business, and money and resource building activities such as the quarrying business at Torry. The lands of Torry in question were mortified to Aberdeen by the influential Menzies family of Pitfodels, who retained a say in the use of their mortification. David Menzies, as part-heritor, was able to relate a number of concerns to the Council and Magistrates over the use and abuse of the lands under the tenancy of Mr. Adam. The quarries referred to were situated in Nigg and Cove, and came under the jurisdiction of Aberdeen’s Master of Mortifications as heritor of half of Torry. Aberdeen let the land to John Adam by means of an Act of Council dated 27th March, 1766, as well as a subsequent act of 1st July, 1767. These can be found in volume 63 of the City’s Council Registers. The original Tack of 1766 granted him a 21yr lease of the quarries lying to the south of the town’s quarries at Cove for an annual rent of £10. The 1767 notation in the Council Register claims the annual rent stands at £5, as well as granting him quarrying rights to the lands of Torry and Cove as far as the southernmost extent of the Barony for an additional £15.
Dyce Quarries - Tyrebagger Besides being used for crib, pavement, and causeway stones, and for house-building, the stones from Tyrebagger have been employed in raising the following works: the Bell-rock Lighthouse; Sheerness Quay Wall; Deptford Quay-Wall; West India Docks; and Sheerness Docks. Stones from the same quarry were formed into pillars for the groins of the London Custom House, and were dressed for the long steps and coping of St Catherine's Docks; and for the most prominent parts of the new Bridge of Don. They were likewise used in building the new London Bridge, and from the same place was that fine block of granite selected which encloses certain urns and other memorials of the present age, and forms the foundation stone of that magnificent structure. In these quarries also a few specimens of dolomite have been found.
Cairngall
Quarry Cairngall, leased by Messrs Alexander Macdonald, Field, & Co., a good substantial stone, known as Aberdeen granite, is Quarried. The Cairngall quarries, in particular, produce a fine small grained stone, admirably adapted for polishing and for ornamental work. In fact, for those purposes, no better material has as yet been found. It was from Cairngall that the sarcophagus for the remains of his late Royal Highness the Prince Consort was taken.
Alexander MacDonald received Letters Patent as “Her Majesty’s Workers in Granite” in 1867 after completing the sarcophagus. When Victoria's coffin was to be placed therein it was discovered that sarcophagus was 6 inches too shallow and temporary wood infill were painted to match. Later matching granite inserts were added to the raised lid. All over the Kingdom monumental work in granite from this and the other Scottish granite quarries were met with. The quarries are situated in a hill which rises about 60 feet above the circumjacent ground; they are worked to some distance right into the hill, and then worked downward; and they have furnished some of the largest and finest blocks for public works and public buildings in the kingdom. They began to be worked, to any considerable extent, in 1808, when they were selected to furnish the blocks for the foundations of the Bell Rock lighthouse; and they furnished the blocks for the foundations of the then new London Bridge, for the pier-walls of the new Houses of Parliament, for the pillars in Covent Garden Market, for the great polished monolithic pillars of St George's Hall in Liverpool, and for the pedestals of several great public statues. The Bell Rock Lighthouse is situated in the North Sea on a partially-submerged reef some 11 miles (17.5 km) southeast of Arbroath on the East Coast of Scotland. One of the major engineering feats of the early 19th Century, it was designed and built by Robert Stevenson (1772 - 1850), with John Rennie (1761 - 1821) serving as Chief Engineer, and came into service in 1811. The lighthouse tower was built from 4 types of stone; granite from Cairngall Quarry near Peterhead was used for the foundation, while the skin of the tower, which had to resist the brunt of the sea, comprises granite from Rubislaw Quarry (Aberdeen) with a core of Old Red Sandstone from Mylnefield Quarry, Kingoodie. Finer sandstone from Craigleith Quarry (Edinburgh) was used in finishing the structure and building the parapet around the light.
Balmedie Quarry
In 1936 the Provost Road, which goes past the derelict Victoria Hall, was the 1st to benefit from the new Tar Metal. In addition to this commercial sandpits were dug in the parish in the 1930s to serve the need for cement. Twenty years later there were workings at Millden, Wester Hatton and Blackdog, producing an annual supply of 1000s of tons of sand.

Aberdeen Monument for Bermuda - Messrs Simpson Brothers, granite merchants, Cotton Street, Aberdeen, have just completed a beautiful monument to be erected at Bermuda "in memory of the non-commissioned Officers and Men of the 1st Battalion the Leicestershire Regiment who died of enteric fever (Typhoid) and from other causes while stationed at Bermuda during the years 1888-90." The monument, which is of granite from the Dyce Quarries, stands 16 feet high, and has an imposing appearance. There are 3 bases. The lowest, which is 4ft square, is of axed granite, and the others are polished. Above these is the pedestal with a handsomely-moulded cornice, and set off by a finely-polished pillar at each of the 4 corners. On the front slab is the inscription already quoted, and on the other sides are the names of the soldiers including 1 quartermaster, 3 sergeants, and 26 privates. An octagonal obelisk rests on the die. It is surmounted by a carved finial, and, like the other parts of the monument, is polished. The stone is of particularly fine character, and it has been worked and finished in a manner which reflects the highest credit on the firm. The monument will be shipped for London next week. |
