Basaltic Lava And Granitic Lava

Summary of basalt vs.

Basaltic lava and granitic lava. Eruptions of granitic lava usually entail a composite cone volcano which produces both lava and pyroclastic material while. Basalt is more common in oceanic crust while granite is more common in continental crust. One major difference between basaltic and granitic magma is their specific mineral contents. It forms from lava flows which extrude onto the surface and cool.

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. This makes granitic lava much more viscous and produces more clastic material and more violent eruptions. High silica content in the andesitic lava contributes to causing this high viscosity and low silica content in the basaltic lava means it is of a lower viscosity. Granitic or rhyolitic lava has a much higher silica content than basaltic lava.
