Compare And Contrast Granitic And Basaltic

Basalt is mafic while granite is felsic basalt is common on both earth and other solar system bodies such as the moon and mars while granite is only common on earth and rare elsewhere in the solar system basalt can form in a few days to months whereas granite plutons can take millions of years to cool and harden.

Compare and contrast granitic and basaltic.

It is mostly made out of quartz mica and feldspar. Poor in silica granitic describes generally light colored silica rich igneous rock that is. Basically read the 4 2 section. Also basaltic rocks are more mafic and granitic.

Answered by anna d. Granite is an intrusive rock and lavas are extrusive rocks. Basaltic mafic granitic felsic andesitic intermediate and ultramafic. Basalt is a mafic rock containing calcium rich plagioclase feldspars and no quartz.

4 2 compare and contrast basic igneous compositions. Granitic rocks are intrusive which means they crystallized underground. Basaltic describes a dense dark colored igneous rock formed from magma rich in magnesium and iron. Basalt is highly mafic while granite is felsic.

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. It is small and this whole thing is the section. Rhyolite is the extrusive rock equivalent to granite. Basalt will be a lot denser which is the main reason why granite is a feature.

Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. Both lavas are formed at different plate boundaries which is why they have different silica contents. Geography tutor 12739 views.

The basaltic lava forms from the hot mantle material at constructive plate boundaries and hotspots whereas the andesitic lava forms at destructive plate boundaries from melting crust. Basalt is extrusive phaneritic while granite is intrusive aphantic. Among other differences the nature of these rocks reveals that basalt is basic in nature whereas granite is acidic in nature.
