granito

roccia ignea intrusiva felsica

AI overview

Granite is a hard rock made mostly of quartz, feldspar, and mica that forms when hot, mineral-rich magma cools slowly underground. It is very common in Earth's continental crust and appears in a wide range of sizes, from small formations just a few centimeters wide to massive formations covering hundreds of square kilometers.

Il granito è una delle rocce più abbondanti sulla superficie terrestre; si tratta di una roccia ignea intrusiva felsica, formata per la maggior parte da feldspati, quarzo e miche. La tessitura è faneritica ipidiomorfa, da equigranulare a porfirica. La grana va da media (> 1 mm) a grossolana e occasionalmente può presentare megacristalli. Il colore è molto variabile e legato principalmente al colore del feldspato potassico e al contenuto dei minerali femici: bianco, giallo, rosa, rosso, bruno e verde.
