Basaltic Lava And Granitic Lava

Basalt is more common in oceanic crust while granite is more common in continental crust.

Basaltic lava and granitic lava.

Eruptions of granitic lava usually entail a composite cone volcano which produces both lava and pyroclastic material while. One major difference between basaltic and granitic magma is their specific mineral contents. Basaltic magma contains between 45 and 55 percent silicon dioxide and is high in magnesium iron and calcium while granitic magma contains between 65 and 75 percent silicon dioxide and only small amounts of those minerals. This makes granitic lava much more viscous and produces more clastic material and more violent eruptions.

First of all you should know the difference between lava and magma magma and lava are both molten liquid rock but magma is moltenrock produced underneath earth surface while it magma erupts on the surface of earth it is called lava. Granitic or rhyolitic lava has a much higher silica content than basaltic lava. Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity so is more runny. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
