Basalt Granite Density

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.

Basalt granite density.

Compared to the familiar granite of the continents basalt ba salt is darker denser and finer grained. It is common both on earth and other planetary bodies. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. All rocks of igneous origin consist of magma or molten earth that finds its way up to.

Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. The density of basalt one of the most common kinds of terrestrial volcanic rocks can be as high as 3 0 g cm 3. Its principle minerals include pyroxene feldspar and olivine. Basalt is the dark heavy volcanic rock that makes up most of the world s oceanic crust.

As it turns out most of the ocean floor is basalt and most of the continents are granite. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It forms from lava flows which extrude onto the surface and cool.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basaltic crust is dark and thin and heavy while granite is light and accumulates. Gabbro s density ranges from 2 7 3 3 g cm 3. When we have to compare granite vs basalt the texture color and appearance plays an important role in determining the type of rock.

Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey. It wants to be there and heat is the key which unlocks the door. For example limestone 2 6 g cm 3 or less quartzite 2 7 g cm 3 and granite 2 7 2 8 g cm 3 are all common low density rocks. Granite is an igneous plutonic rock which is.

Rock density is very sensitive to the minerals that compose a particular rock type. Some of it erupts on land too but to a first approximation basalt is an oceanic rock. Some meteorites have low densities 3 0 g cm 3 but such meteorites are rare among meteorites.
