Basalt Vs Granite Density

Summary of basalt vs.

Basalt vs granite density.

The hardness of granite is 6 7 and that of basalt is 6. Granite is a felsic rock meaning that it has a high silicon content. It is common both on earth and other planetary bodies. 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. Basalt and granite are two types of igneous rocks that we can find on earth. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Gabbro s density ranges from 2 7 3 3 g cm 3.

Properties of rock is another aspect for granite vs basalt. Basalt wikipedia wikimedia foundation 13 sept. Grant mason from the byu department of physics and astronomy discusses samples of granite and basalt rock.

Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey colors. Summary basalt vs granite. This range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains. This is measured either as a decimal between 0 and 1 or as a percentage.

And not all granites basalts and gabbros contain exactly the same minerals. As it turns out most of the ocean floor is basalt and most of the continents are granite. Since gabbro and basalt are made of the same minerals their densities are similar. 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.

Appearance of granite is veined or pebbled and that of basalt is dull and soft. It wants to be there and heat is the key which unlocks the door. Basaltic crust is dark and thin and heavy while granite is light and accumulates. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.

It is mostly made out of quartz mica and feldspar. Its principle minerals include pyroxene feldspar and olivine.
