Basaltic lava vs granitic lava.

Granitic lava flows called rhyolitic when they form at the surface are rare and do not cover much ground. It forms from lava flows which extrude onto the surface and cool. This makes granitic lava much more viscous and produces more clastic material and more violent eruptions. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Its principle minerals include pyroxene feldspar and olivine. Summary of basalt vs. A lava butte is generally basaltic lava. Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity so is more runny.

Summary basalt vs granite. Ferromagnesian dark coloured lavas such as basalt characteristically form flows known by the hawaiian names pahoehoe and aa or a a. 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. One major difference between basaltic and granitic magma is their specific mineral contents.

It is common both on earth and other planetary bodies. 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. 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. Pahoehoe lava flows are characterized by smooth gently undulating or broadly hummocky surfaces.

Is basaltic magma or granitic magma hotter. Eruptions of granitic lava usually entail a composite cone volcano which produces both lava and pyroclastic material while. 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. Other articles where basaltic lava is discussed.

Basalt and granite are two types of igneous rocks that we can find on earth. The liquid lava flowing beneath a thin still plastic crust drags and wrinkles it into tapestry like.
