El granito es una roca ígnea intrusiva de color claro, de composición félsica formada esencialmente por cuarzo, feldespato alcalino, plagioclasa y mica. [1] El término granito abarca varias rocas de aspecto granular y de colores claros, pero con proporciones diferentes entre sus minerales. Para referirse a todas ellas los geólogos han definido el término granitoide.

🎓 La geología de la superficie de la tierra está siendo moldeada continuamente por la actividad volcánica. Este proceso natural comienza en las profundidades de la corteza, cuando el magma supercalentado (un material de roca líquida formado por minerales y gases) se eleva hacia la superficie y entra en erupción a través de grietas o respiraderos.

Peridotite is the name for rocks of the upper mantle, and Komatiite is the name for extrusive lavas that are essentially of Peridotite composition. The latter are found primarily in very old rocks (Archean) that formed soon after the formation of the first crust (crust was thin, very mobile, and convection was vigorous).

Basalt is an effusive rock of volcanic origin, the result of lava flows from the lithosphere. The pressure reduction and the rapid cooling in contact with the Earth's atmosphere stopped the process of crystallization, giving this stone a very compact structure with a dark or black microcrystalline paste with a relatively low silica content.
