About Granite Granite is a common and widely occurring type of invasive, felsic, igneous rock. Granite has a medium to coarse texture, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. The term "Granite" is derived from a Latin word "Granum" meaning "grain" because of its granular nature. Granite is currently known only on Earth where it forms a major part of continental crust. Granite often occurs as relatively small, less than 100 km² stock masses (stocks) and in batholiths that are often associated with orogenic mountain ranges. Small dikes of granitic composition called aplites are often associated with the margins of granitic intrusions. In some locations very coarse-grained pegmatite masses occur with granite. Granite has been intruded into the crust of the Earth during all geologic periods, although much of it is of Precambrian age. Granitic rock is widely distributed throughout the continental crust of the Earth and is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Granite is nearly always massive (lacking internal structures), hard and tough, and therefore it has gained widespread use as a construction stone. The average density of granite is 2.75 g/cm3 and its viscosity at standard temperature and pressure is ~4.5 • 1019 Pa•s. A worldwide average of the average proportion of the different chemical components in granites, in descending order by weight percent, is: SiO2 — 72.04% [Silicon Di-oxide] Al2O3 — 14.42% [Aluminium Oxide] K2O — 4.12% [Potassium Oxide] Na2O — 3.69% [Sodium Oxide] CaO — 1.82% [Calcium Oxide] FeO — 1.68% [Ferrous Oxide] Fe2O3 — 1.22% [Ferric Oxide] MgO — 0.71% [Magnesium Oxide] TiO2 — 0.30% [Titanium Di-oxide] P2O5 — 0.12% [Phosphorous Oxide] MnO — 0.05% [Manganese Oxide] It takes heavy shining polish, which are used as architectural stone for interior and exterior walls, floors and other architectural structures.
