Compare And Contrast Granitic And Basaltic

Basalt will be a lot denser which is the main reason why granite is a feature.

Compare and contrast granitic and basaltic.

Basalt is extrusive phaneritic while granite is intrusive aphantic. 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. It is mostly made out of quartz mica and feldspar. 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.

Poor in silica granitic describes generally light colored silica rich igneous rock that is. Of the two basalt is darker and consists of fine grained minerals such as magnesium and iron while granite is lighter and consist of feldspar and quartz. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. Basaltic mafic granitic felsic andesitic intermediate and ultramafic.

4 2 compare and contrast basic igneous compositions. Granitic rocks are intrusive which means they crystallized underground. Also basaltic rocks are more mafic and granitic. Granite is a felsic rock meaning that it has a high silicon content.

Both lavas are formed at different plate boundaries which is why they have different silica contents. It is small and this whole thing is the section. Rhyolite is the extrusive rock equivalent to granite. Basalt is highly mafic while granite is felsic.

Basalt is a mafic rock containing calcium rich plagioclase feldspars and no quartz. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Answered by anna d. Basaltic describes a dense dark colored igneous rock formed from magma rich in magnesium and iron.

Basically read the 4 2 section. Granite is an intrusive rock and lavas are extrusive rocks. Geography tutor 12739 views.
