granítica

Granítica is the adjectival form used in geology and construction to refer to granite or granitic rocks. In geology, granítica describes igneous rocks that are light-colored, coarse-grained plutonic rocks dominated by quartz and feldspar, with minor mica or amphibole. The typical mineral assemblage includes quartz, potassium feldspar and plagioclase; accessory minerals such as biotite, muscovite, hornblende, apatite and zircon.

Granitic rocks crystallize from silica-rich magma that cools slowly below the surface, producing large crystals. They are part of the felsic family and have high silica and alkali content. Within this broad group, granite is the best known, while granodiorite and tonalite represent related varieties with different feldspar ratios.

Granítica rocks are common in the continental crust and form major plutonic domains called batholiths and plutons. They are widespread on many continents and are often exposed by erosion.

In construction and architecture, granítica or granite is valued for its durability, hardness, and aesthetic variety. It is widely used as dimension stone, for building facades, flooring, monuments, and countertops. The term granítica may also describe stone with a granite-like appearance or texture used in decorative applications.

Note: The word granítica comes from granítico/granito, rooted in granite, itself from Latin granum "grain," reflecting its granular texture.
