Conditions during the formation of granitic magmas by ...

Granitic magmas extracted from crustal sources can form over a wide variety of P, T and aH 2 O conditions. Both fluid-present and effectively fluid-absent conditions can yield granitic magmas, though the majority are formed through high-T, fluid-absent reactions because, in the deep crust, most available H 2 O within rock bodies is contained within minerals rather than in free fluids.

Granite Dells, Prescott, Arizona | AZGS

Granitic rock exposed at the Dells is Proterozoic in age (1,400 Ma). The granitic melt was intruded into the ancient crust where it cooled and crystallized. It has since been exhumed and raised to the surface. The rounded appearance of individual boulder is the result of spheroidal weathering - a process whereby minerals, feldspars and micas, are chemically attacked along joints, effectively ...

What Is Granite And How Is It Formed? - Geology In

Granite has a felsic composition and is more common in recent geologic time in contrast to Earth's ultramafic ancient igneous history. Felsic rocks are less dense than mafic and ultramafic rocks, and thus they tend to escape subduction, whereas basaltic or gabbroic rocks tend to sink into the mantle beneath the granitic …
