silica-rich
High in silicon
Silica-rich describes materials containing high concentrations of silicon dioxide, the compound that forms quartz, sand, and glass.
In geology, silica-rich rocks like granite are lighter in color and more viscous when molten than silica-poor basalts.
Silica-rich magma tends to produce explosive volcanic eruptions.
