    UsageSignificanceGeologyDefinitionsFeaturesApplicationsAdvantagesOther usesFormationGranite is the best-known igneous rock. Many people recognize granite because it is the most common igneous rock found at Earth's surface and because granite is used to make many objects that we encounter in daily life. These include counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments. Granite is used all around us especially if you live in a city.

    DescriptionRelation to MiningUsesGranite is the most widespread of igneous rocks, underlying much of the continental crust. Granite is an intrusive igneous rock. Intrusive rocks form from molten material (magma) that flows and solidifies underground, where magma cools slowly. Eventually, the overlying rocks are removed, exposing the granite. Granites usually have a coarse texture (individual minerals are visible without magnification), because the magma coolSee more on mineralseducationcoalition

    The term “granite” is used for granite and a group of intrusive igneous rocks with similar textures and slight variations in composition and origin.

    OverviewOccurrenceMineralogyOriginAscent and emplacementWeatheringNatural radiationIndustry

    Granite containing rock is widely distributed throughout the continental crust. Much of it was intruded during the Precambrian age; it is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Outcrops of granite tend to form tors and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite often occurs as relatively small, less than 100 km stock masses (stocks) a
