  • Granite: Igneous Rock Pictures, Definition & More

    Granite is a lightcolored igneous rock with grains large enough to be visible with the unaided eye It forms from the slow crystallization of magma below Earth's surface Granite is composed mainly of quartz and feldspar with minor amounts of mica,Granite (the word rhymes with “SPAN it”) is one of the igneous rocks, rocks that form by cooling from molten magma Granite is perhaps the bestknown of the intrusive igneous rocks, those which form deep below the surfaceIgneous Rocks Granite | Actforlibraries

  • Granite Petrology & Igneous Rock Information

    Granite is a common and widelyoccurring group of intrusive felsic igneous rocks that forms at great depths and pressures under continents Granite consists of orthoclase, plagioclase quartz, hornblende, biotite, muscovite and minor accessories such as magnetite, garnet, zircon and apatite minerals Rarely a pyroxene is presentGranites are the example of the plutonic intrusive igneous rocks which are formed deep within the earth Since the rate of cooling and solidification of magmas inside the earth is very slow because of very high temperature prevailing under­ground and hence granites become coarsegrained due to full development of largesized grainsGranites and Basalts | Igneous Rocks | Geography
