What Is Basalt? - ThoughtCo

Basalt is the dark, heavy volcanic rock that makes up most of the world's oceanic crust. Some of it erupts on land, too, but to a first approximation, basalt is an oceanic rock. Compared to the familiar granite of the continents, basalt ("ba-SALT") is darker, denser and finer grained.

How does silica affect the color of igneous rocks? | Socratic

Dec 20, 2015 · Rocks that are high in silica tend to be pale in colour. Pure silica has the chemical formula SiO_2 - silicon dioxide. Glass is silica that has an amorphous structure, which means the silicon and oxygen atoms aren't in a repeating lattice. Quartz is the form that pure silica takes in nature. It has a tectosilicate structure, which means the atoms form a lattice of tetrahedra bonded together .

Andesite | Encyclopedia.com

Andesite's character usually results from the melting and assimilation of rock fragments by magma rising to the surface. Rocks nearer the surface tend to be higher in silicon, because silicon is less dense than iron and magnesium, components that increase at greater depths. An andesite can thus be viewed very roughly as a basalt contaminated .

USGS: Volcano Hazards Program Glossary - Silica

Silicon dioxide, the most abundant rock-forming compound on Earth and the predominant molecular constituent of volcanic rocks and magmas.It tends to polymerize into molecular chains, increasing the viscosity of the magma. Basaltic magma, having lower SiO2, is fairly fluid, but with increasing contents of SiO2, andesite, dacite, and rhyolite magmas become progressively more viscous.
