How does granitic lava differ from basaltic lava?

Granitic or rhyolitic lava has a much higher silica content than basaltic lava. This makes granitic lava much more viscous and produces more clastic material and more violent eruptions. Eruptions of granitic lava usually entail a composite cone volcano which produces both lava and pyroclastic material while ... read more
