It forms from lava flows which extrude onto the surface and cool.
Basalt vs granite density.
Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite.
Granite is a felsic rock meaning that it has a high silicon content.
Its principle minerals include pyroxene feldspar and olivine.
Porosity and density.
Appearance of granite is veined or pebbled and that of basalt is dull and soft.
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
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.
Grant mason from the byu department of physics and astronomy discusses samples of granite and basalt rock.
And not all granites basalts and gabbros contain exactly the same minerals.

Since gabbro and basalt are made of the same minerals their densities are similar.
Gabbro s density ranges from 2 7 3 3 g cm 3.
Summary basalt vs granite.
Basalt and granite are two types of igneous rocks that we can find on earth.
The hardness of granite is 6 7 and that of basalt is 6.
Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey colors.
Basalt wikipedia wikimedia foundation 13 sept.
It wants to be there and heat is the key which unlocks the door.
As it turns out most of the ocean floor is basalt and most of the continents are granite.
Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.
This range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains.
Properties of rock is another aspect for granite vs basalt.
Basaltic crust is dark and thin and heavy while granite is light and accumulates.
In crystalline rocks like granite which have tight interlocking mineral grains porosity is normally quite low less than 1 percent.
The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core.
It is common both on earth and other planetary bodies.
