Basaltic Lava Vs Granitic Lava

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.

Basaltic lava vs granitic lava.

Pahoehoe lava flows are characterized by smooth gently undulating or broadly hummocky surfaces. 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. Magnus design black granite mortar and pestle. Other articles where basaltic lava is discussed.

Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity so is more runny. It forms from lava flows which extrude onto the surface and cool. Eruptions of granitic lava usually entail a composite cone volcano which produces both lava and pyroclastic material while. Granitic lava flows called rhyolitic when they form at the surface are rare and do not cover much ground.

Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Ferromagnesian dark coloured lavas such as basalt characteristically form flows known by the hawaiian names pahoehoe and aa or a a. Basalt wikipedia wikimedia foundation 13 sept. This makes granitic lava much more viscous and produces more clastic material and more violent eruptions.

The ancient mexican version of the mortar and pestle a molcajete is traditionally carved out of a single piece of basalt. 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. Summary of basalt vs. One major difference between basaltic and granitic magma is their specific mineral contents.

Summary basalt vs granite. Its principle minerals include pyroxene feldspar and olivine. 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. It is common both on earth and other planetary bodies.

A lava butte is generally basaltic lava. Granitic or rhyolitic lava has a much higher silica content than basaltic lava.
