What Are the Differences Between Basaltic and Granitic Magma?

Due to their high content of silica and low iron and magnesium contents, rhyolitic magmas form highly viscous lavas. As a result, many eruptions of rhyolite are highly explosive, and rhyolite occurs more frequently as pyroclastic rock than as lava flows. Rhyolitic ash flow tuffs are the only volcanic product with volumes rivaling those of flood basalts. Rhyolites also occur as breccias or in lava domes, volcanic plugs, and dikes.
