Granitisia

Granitisia is a fictional geological term that describes a hypothetical condition of a planet's crust becoming infused with a significant proportion of granite-like material. This could manifest as an increased prevalence of igneous rocks with a coarse-grained texture, rich in quartz and feldspar, forming vast continental landmasses. In this theoretical scenario, the geological processes that lead to the formation and differentiation of such a crust would be dominant. This might involve intense periods of volcanic activity and subsequent slow cooling and solidification of magma deep beneath the surface.

The implications of granitisia for a planet would be far-reaching. A predominantly granitic crust would likely be less dense than other crustal types, potentially leading to higher continental plateaus and a different distribution of oceans and land. The mineral composition would also influence the planet's geochemistry, affecting the availability of certain elements for potential life. Furthermore, the tectonic activity associated with such a crust might differ, with a focus on processes that build up and thicken these granitic regions. This concept is primarily explored in speculative geology and astrobiology to model diverse planetary environments.
