Basaltic Lava Vs Granitic Lava

Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Basaltic lava vs granitic lava.

Summary basalt vs granite. This makes granitic lava much more viscous and produces more clastic material and more violent eruptions. Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity so is more runny. Granitic lava flows called rhyolitic when they form at the surface are rare and do not cover much ground.

The liquid lava flowing beneath a thin still plastic crust drags and wrinkles it into tapestry like. Other articles where basaltic lava is discussed. 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. Magnus design black granite mortar and pestle.

Basalt wikipedia wikimedia foundation 13 sept. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.

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. Summary of basalt vs.

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. The ancient mexican version of the mortar and pestle a molcajete is traditionally carved out of a single piece of basalt. A lava butte is generally basaltic lava.
