Basaltic Igneous Rocks Are Lower In Density Than Granitic Rocks

Lower in density than basaltic rocks d. The difference between granites and basalts is in silica content and their rates of cooling. Igneous rocks are formed by the crystallisation of a magma.

And if you know your igneous petrology you will see that the more mafic rich in magnesium and iron a rock is the greater its density.

Basaltic igneous rocks are lower in density than granitic rocks. Igneous rock with a mineral composition between that of basaltic and granitic rock. They have a higher silica content and a lower iron and magnesium content than the other types of rock. Consequently due to buoyancy the continental crust rides above the oceanic lithosphere and. Lava that cools quickly forms rocks.

Rich in quartz and potassium feldspar. Granite and rhyolite are felsic igneous rocks intermediate igneous rocks have a density. Light colored igneous rock of lower density than basaltic rock formed from magma rich in silica but poor iron and magnesium. High in silica content b.

Granitic igneous rocks are all of the following except. Intrusive slowly cooled inside the crust. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. High in iron content.

A basalt is about 53 sio2 whereas granite is 73. Rock density is very sensitive to the minerals that compose a particular rock type. The density of the continental granitic lithosphere is lower than oceanic basaltic lithosphere. Plutonic rock formed in the earth.

Continental crust density 2 7 2 8. This magma is thick and stiff.
