Compare And Contrast Basaltic And Granitic Igneous Rocks

Igneous rocks can be classified by composition based on the major minerals in the rocks.

Compare and contrast basaltic and granitic igneous rocks.

Rocks are also classified on the basis of their hardness which ranges from 1 to 10 on moh s hardness scale as types of hard rocks types of soft rocks and rocks with medium hardness. Basalt and granite are similar in the they are both igneous silicate rocks and common on earth. Basalt is extrusive mafic and common throughout the solar system whereas granite is intrusive felsic and common only on earth. Basalt is an extrusive igneous rock whereas granite is an intrusive ingenuous rock.

Poor in silica granitic describes generally light colored silica rich igneous rock that is. Light colored rocks have granitic compositions. Light colored igneous rocks are more granitic felsic in composition and contain more feldspar and silica. 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 describes a dense dark colored igneous rock formed from magma rich in magnesium and iron. Dark colored igneous rocks are more basaltic mafic in composition and contain more iron and magnesium. Pyroxene andalusite corundum tourmaline garnet and topaz are also relatively common mafic. Dark colored rocks that contain only olivine and pyroxene are ultramafic rocks.

One other difference between basalt and granite pertains to the way these two types of rocks split when putting under pressure. While basalt rocks split along columnar planes granite rocks give way along horizontal planes. Felsic andesitic mafic and ultramafic composition. One major difference between basaltic and granitic magma is their specific mineral contents.

You can also go through the reserves of igneous rocks. Distinguish among the four basic compositional groups of igneous rocks. Compare igneous rocks and find the rock with most attractive texture. Some of the igneous rocks rocks are granite obsidian basalt diorite gabbro.

Dark colored rocks have basaltic compositions. We all come across rocks in our day to day life be it a stone pebble sand or just mud.
