A crystalline, granular rock, consisting of quartz, feldspar, and mica, and usually of a whitish, grayish, or flesh-red color. It differs from gneiss in not having the mica in planes, and therefore in being destitute of a schistose structure.
A light colored igneous rock comprised of the silicon and aluminum-rich minerals quartz and feldspar. Granites are the most abundant igneous rock that form by crystallization of magma within continental crust.
A granular igneous rock composed essentially of quartz, feldspar, and mica. The feldspar is generally the variety containing potassium (orthoclase and microcline) but some limesoda feldspar may be present. Hornblende, apatite, zircon, and magnetite are usually present in minor amounts.
A coarse-grained, intrusive igneous rock composed primarily of light colored minerals such as quartz, orthoclase, sodium plagioclase and muscovite mica. Granite is thought to be one of the main components of continental crust.
a visibly granular, crystalline rock of predominantly interlocking texture, composed essentially of alkalic feldspars and quartz; this is true granite. Feldspar is generally present in excess of quartz, and accessory minerals (chiefly micas, hornblende, or more rarely pyroxene) are commonly present. The alkalic feldspars may be present (1) as individual mineral species (2) as isomorphous or mechanical intergrowths with each other or (3) as chemical intergrowths with the lime feldspar molecule, but 80 + 3% of the feldspar must be composed of the potash or soda feldspar molecules.

a term that includes granite (as defined above), gneiss, gneissic granite, granite gneiss, and the rock species known to petrologists as syenite, monzonite, and granodiorite, species intermediate between them, the gneissic varieties and gneisses of corresponding mineralogic compositions and the mineralogic compositions and the corresponding varieties of porphyritic textures. The term commercial granite shall also include other feldspatic crystalline rocks of similar textures, containing minor amounts of accessory minerals, used for special decorative purposes, and known to petrologists as anorthosite and laurvikite.

Light-colored, medium- to very coarse-grained intrusive igneous rock, commonly massive-appearing, lacking layering or banding; composed of quartz, feldspar, and commonly muscovite mica with minor amounts of dark minerals. Granite and granitic gneiss were quarried for use as dimension stone. Very limited quarrying continues.
A common igneous rock that crystallizes slowly, within the earth, so that mineral crystals have time to grow to relatively large size. Granites are usually low in iron-magnesium minerals and contain abundant quartz and feldspar.
A type of stone formed by the slow cooling or crystallization of melted rock. The three main components of granite are feldspar, quartz and mica. Feldspar has several different colors or forms, and is primarily responsible for the apparent over-all color of the granite. Quartz is clear and appears to take color from the feldspar and mica around it. Mica shows as black flecks and makes up less than 20 % of the components of a granite.
An igneous rock of visible crystalline formation that is formed by magma cooling slowly, deep below the earths crust. Usually found in shades of whitish grey but potash feldspar can give it a red or pinkish hue. It is the most common intrusive rock exposed on the earth's surface.
Granite is a form of Igneous Rock, created by the cooling of molten magma. This is a luxury floor covering as it is an expensive product. The floor structure needs consideration, as it is very heavy. It is hardwearing and resistant to chemicals. It has a timeless look. If highly polished it is slippery, but a honed finish provides a more manageable finish. It comes in limited colours â€“ black, red, green, grey, blue, pink.
A coarse grained igneous rock composed of quartz (over 20%) and feldspar in which plagioclase and alkali feldspar occur in approximately equal proportions. A series of granite masses occur forming the "spine" of south-west England ranging from the Isles of Scilly in the West to Dartmoor in the east. Two important granites are present around the Fal Estuary - the Carnmenellis Granite and the St. Austell Granite.
Geologically, igneous rock with crystals or grains of visible size consisting mainly of quartz and the sodium or potassium feldspar. In building stone and gravestones, crystalline silicate rock with visible grains. The commercial term includes gneiss and igneous rocks that are not granite in the strictest sense.
A coarse-grained intrusive igneous rock with at least 65% silica. Quartz, plagioclase feldspar and potassium feldspar make up most of the rock and give it a fairly light color. Granite has more potassium feldspar than plagioclase feldspar. Usually with biotite, but also may have hornblende. more details...
A fine to course grained igneous rock, generally consisting of quartz, feldspar and rock, formed by volcanic action and cooled slowly under great pressure. It is the hardest building stone with a very dense grain. Example: Granite Boulders
This igneous metamorphic stone originates from volcanic activity, and is typically course-grained. It varies in color from very light to black, and the quartz and feldspar crystals it contains give the stone a reflective quality. Classified as a #8 on a standard scale of hardness (a diamond is a #10), this indicates that granite is an extremely difficult stone to carve, but it is still a popular medium for sculpture because of its durability. The surface can be smoothed to a high polish.
A pink-colored, felsic, plutonic rock that contains potassium and usually sodium feldspars, and has a quartz content of about 10%. Granite is commonly found on continents but virtually absent from the ocean basins. A coarse-grained, intrusive igneous rock composed of quartz, orthoclase feldspar, sodic plagioclase feldspar, and micas. Also sometimes a metamorphic product.
A coarse grained igneous rock containing the minerals mica, quartz and feldspar. Granite forms from the solidification of magma deep below the Earth's surface. The magma cools very slowly, allowing big crystals to be formed.
highly felsic igneous plutonic rock, typically light in color; rough plutonic equivalent of rhyolite. Granodiorite - igneous plutonic rock, less felsic than granite, typically light in color; rough plutonic equivalent of dacite.
Granite is a type of igneous rock (volcanic rock that has cooled) that is light-colored and coarse grained. Granite is characterized by the minerals orthoclase and quartz with some plagioclase feldspar and iron-magnesium minerals. Granite underlies much of the continents.
1. In technical geologic terms, igneous rock with crystals or grains of visible size and consisting mainly of quartz and the sodium or potassium feldspars. 2. In building stone, crystalline silicate rock with visible grains. The commercial term includes gneiss (a metamor phic rock) and igneous rocks that are not granite in strict sense.
a light-coloured intrusive igneous rock made up of the minerals quartz and feldspar with biotite and / or muscovite mica. The crystals are big enough to be visible without magnification. Granite is formed from the melting of the continental crust rocks.
Highly felsic igneous plutonic rock, typically light in color; rough plutonic equivalent of rhyolite. Granite is actually quite rare in the U.S.; often the term is applied to any quartz-bearing plutonic rock.
A common igneous rock composed of quartz, orthoclase, and hornblende, often accompanied by pyroxene or mica. It is called granite because of the granular surface. Granite is frequently used for buildings and monuments.
A light-colored, coarse-grained igneous rock formed by cooling of silica-rich magma below the surface of the earth. Granite is considered to be the average composition of the continental crust of the earth.
Granite is a natural and extremely hard wearing stone ideally suited for kitchen benchtops and vanities that require a durable working surface. Similar to all natural products, Granite has many features that compliment each other with its colour range and texture variety, along of course with its renowned strength and longevity.
pigment which consists of spots of on color surrounded by bands of other colors. When used with the proper color map, it can create a very convincing stone texture.

The height of each individual triangle is defined by the color of the pixel in the corresponding location in the source image. This is the easiest and least painful way to create mountains.
