Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth. Learn more about the properties and uses o
Granite commonly contains high concentrations of uranium, with subsequent high exhalation of radon gas. The geology of the West Coast Peninsula of South Africa is dominated by granite. No measurements of radon gas has, however, been undertaken in, or near the towns of the peninsula and a ...
Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. The three major classes of rock are

Granite is a rock composed of quartz, feldspar, and other minerals. There are three basic types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form gemstones depending on the elements present, cooling time, and the environment. Amethyst, citrine, diamonds, and topaz are some of...
(1)It was formed in the tectonic setting of the Diwa block-faulting orogenic belt after platform, and restricted to the big linear fault zone. (2)There is a distinctive association formation series that was three in one formed by the metamorphic rock, the migmatite and the granite, and ...
4. Granite Chemical Composition:Silica, Alumina A common type of igneous rock, granite is intrusive in nature and have a granular texture. Granites usually have high amounts of quartz and feldspar (alkali feldspar), mica and certain other amphibole minerals are present in small qualities. ...
majority of the earth's crust. When an igneous rock is given a name, there are two characteristics that are important: composition and texture. Composition is defined as what the rock is made of and texture is how large the crystals are. Examples of igneous rocks are granite, obsidian and...
