    OverviewMineralogyOccurrenceOriginAscent and emplacementWeatheringGranite is nearly always massive, hard, and tough. These properties have made granite a widespread construction stone throughout human history. The average density of granite is between 2.65 and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–61019 Pas. The melting temperature of dry granite at ambient pressure is 1215–1260 °C; it is strongly reduced in the presence of water, down to 650 °C at a few kBar pressure. Granite has poor...
