Compare And Contrast Granitic And Basaltic

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.

Compare and contrast granitic and basaltic. Also basaltic rocks are more mafic and granitic. Granitic rocks are intrusive which means they crystallized underground. Answered by anna d. Rhyolite is the extrusive rock equivalent to granite.

Basalt is extrusive phaneritic while granite is intrusive aphantic. 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. Basaltic rocks are extrusive meaning they crystallized above ground. Basalt is highly mafic while granite is felsic.

It is mostly made out of quartz mica and feldspar. Basically read the 4 2 section. Poor in silica granitic describes generally light colored silica rich igneous rock that is. Basaltic mafic granitic felsic andesitic intermediate and ultramafic.

Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Basalt is a mafic rock containing calcium rich plagioclase feldspars and no quartz.

Both lavas are formed at different plate boundaries which is why they have different silica contents. Granite is an intrusive rock and lavas are extrusive rocks. Basaltic describes a dense dark colored igneous rock formed from magma rich in magnesium and iron. 4 2 compare and contrast basic igneous compositions.

Granite is a felsic rock meaning that it has a high silicon content. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. Among other differences the nature of these rocks reveals that basalt is basic in nature whereas granite is acidic in nature.
