Granite: The specimen above is a typical granite. It is about two inches across. The grain size is coarse enough to allow recognition of the major minerals. The pink grains are orthoclase feldspar, and the clear to smoky grains are quartz or muscovite. The black grains can be biotite or hornblende.
Many rocks identified as "granite" using the introductory course definition will not be called "granite" by the petrologist - they might instead be alkali granites, granodiorites, pegmatitesor aplites.
A petrologist might call these "granitoid rocks" rather than granites. There are other definitions of granite based upon mineral composition.
The accompanying chart illustrates the range of granite compositions.

From the chart you can see that orthoclase feldsparquartzplagioclase feldsparmicas, and amphiboles can each have a range of abundances. Pegmatite: Photograph of a granite with very large crystals of orthoclase feldspar.
Granites composed mainly of crystals over one centimeter in diameter are known as "pegmatites. Clockwise from top left they are: granitegneisspegmatiteand labradorite. Click on any of their names above for an enlarged view. Each of the images above represents a slab of polished rock about eight inches across.
The word "granite" is used by people who sell and purchase cut stone for structural and decorative use. These "granites" are used to make countertops, floor tiles, curbing, building veneer, monuments, and many other products. In the commercial stone industry, a "granite" is a rock with visible grains that are harder than marble. Under this definition, gabbrobasaltpegmatiteschistgneisssyenite, monzonite, anorthosite, granodiorite, diabasedioriteand many other rocks will be called "granite.
Granite counter tops: Granite counter tops in a new kitchen. Granite is the rock most often quarried as a "dimension stone" a natural rock material that has been cut into blocks or slabs of specific length, width, and thickness. Granite is hard enough to resist abrasion, strong enough to bear significant weight, inert enough to resist weathering, and it accepts a brilliant polish.
These characteristics make it a very desirable and useful dimension stone. Most of the granite dimension stone produced in the United States comes from high-quality deposits in five states: Massachusetts, Georgia, New Hampshire, South Dakota, and Idaho.
Granite has been used for thousands of years in both interior and exterior applications. Rough-cut and polished granite is used in buildings, bridges, paving, monuments, and many other exterior projects.
Indoors, polished granite slabs and tiles are used in countertops, tile floors, stair treads, and many other practical and decorative features. High price often reduces the popularity of a construction material, and granite often costs significantly more than man-made materials in most projects.
However, granite is frequently selected because it is a prestige material, used in projects to produce impressions of elegance, durability, and lasting quality. Granite is also used as a crushed stone or aggregate. In this form it is used as a base material at construction sites, as an aggregate in road construction, railroad ballast, foundations, and anywhere that a crushed stone is useful as fill.
Granitic rocks: This triangular diagram is a classification method for granitic rocks. It is based upon the relative abundance of feldspars K-Na-Ca and quartz. Mafic elements are not considered.
It is modified after a classification chart prepared by the International Union of Geological Sciences. Image and modification by the United States Geological Survey.
Most introductory geology textbooks report that granite is the most abundant rock in the continental crust. At the surface, granite is exposed in the cores of many mountain ranges within large areas known as "batholiths," and in the core areas of continents known as "shields.
The large mineral crystals in granite are evidence that it cooled slowly from molten rock material. That slow cooling had to have occurred beneath Earth's surface and required a long period of time to occur. If they are today exposed at the surface, the only way that could happen is if the granite rocks were uplifted and the overlying sedimentary rocks were eroded. In areas where Earth's surface is covered with sedimentary rocks, granites, metamorphosed granites, or closely related rocks are usually present beneath the sedimentary cover.
These deep granites are known as "basement rocks. What is Granite Used For? Article by: Hobart M. KingPh. Find Other Topics on Geology. Maps Volcanoes World Maps. Did You Know? Curling stones are made from special types of granite.
The Brihadeeswarar Temple dedicated to Lord Shiva was built in The massive Gopuram ornate, upper section of shrine is believed to have a mass of around 81 tonnes. It was the tallest temple in south India. Imperial Roman granite was quarried mainly in Egypt, and also in Turkey, and on the islands of Elba and Giglio.
Granite became "an integral part of the Roman language of monumental architecture". Beginning in Late Antiquity the granite was reused, which since at least the early 16th century became known as spoliation. Through the process of case-hardeninggranite becomes harder with age. The technology required to make tempered steel chisels was largely forgotten during the Middle Ages.
As a result, Medieval stoneworkers were forced to use saws or emery to shorten ancient columns or hack them into discs. Giorgio Vasari noted in the 16th century that granite in quarries was "far softer and easier to work than after it has lain exposed" while ancient columns, because of their "hardness and solidity have nothing to fear from fire or sword, and time itself, that drives everything to ruin, not only has not destroyed them but has not even altered their colour.
In some areas, granite is used for gravestones and memorials. Granite is a hard stone and requires skill to carve by hand. Until the early 18th century, in the Western world, granite could be carved only by hand tools with generally poor results.
A key breakthrough was the invention of steam-powered cutting and dressing tools by Alexander MacDonald of Aberdeeninspired by seeing ancient Egyptian granite carvings. Inthe first polished tombstone of Aberdeen granite to be erected in an English cemetery was installed at Kensal Green Cemetery.
It caused a sensation in the London monumental trade and for some years all polished granite ordered came from MacDonald's. The royal sarcophagus at Frogmore was probably the pinnacle of its work, and at 30 tons one of the largest.
It was not until the s that rival machinery and works could compete with the MacDonald works. Modern methods of carving include using computer-controlled rotary bits and sandblasting over a rubber stencil. Leaving the letters, numbers, and emblems exposed on the stone, the blaster can create virtually any kind of artwork or epitaph.
The stone known as "black granite" is usually gabbrowhich has a completely different chemical composition. Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments.
Aberdeen in Scotland, which is constructed principally from local granite, is known as "The Granite City". Because of its abundance in New Englan granite was commonly used to build foundations for homes there. The Granite RailwayAmerica's first railroad, was built to haul granite from the quarries in Quincy, Massachusettsto the Neponset River in the s.
Engineers have traditionally used polished granite surface plates to establish a plane of reference, since they are relatively impervious, inflexible, and maintain good dimensional stability.
Sandblasted concrete with a heavy aggregate content has an appearance similar to rough granite, and is often used as a substitute when use of real granite is impractical.
Granite tables are used extensively as bases or even as the entire structural body of optical instruments, CMM s, and very high precision CNC machines because of granite's rigidity, high dimensional stability, and excellent vibration characteristics. A most unusual use of granite was as the material of the tracks of the Haytor Granite TramwayDevon, England, in Granite block is usually processed into slabs, which can be cut and shaped by a cutting center.
In military engineering, Finland planted granite boulders along its Mannerheim Line to block invasion by Russian tanks in the winter war of Curling stones are traditionally fashioned of Ailsa Craig granite.
The first stones were made in the s, the original source being Ailsa Craig in Scotland. Between 60 and 70 percent of the stones used today are made from Ailsa Craig granite, although the island is now a wildlife reserve and is still used for quarrying under license for Ailsa granite by Kays of Scotland for curling stones. Granite is one of the rocks most prized by climbers, for its steepness, soundness, crack systems, and friction.
Granite rock climbing is so popular that many of the artificial rock climbing walls found in gyms and theme parks are made to look and feel like granite. Granite was used for setts on the St. Louis riverfront and for the piers of the Eads Bridge background.
