Granitic lava also known as rhyolitic lava is lava that contains 20 percent more silica also called quartz than basaltic lava the most common.
Although basaltic magma can result in basaltic rocks and granitic magma can result in granitic rocks they can also form other rocks depending on how quickly the magma cools.
Granite definition a coarse grained igneous rock composed chiefly of orthoclase and albite feldspars and of quartz usually with lesser amounts of one or more other minerals as mica hornblende or augite.

Eruptions of granitic lava usually entail a composite cone volcano which produces both lava and pyroclastic material while.
It forms from the slow crystallization of magma below earth s surface.
