READ MORE· Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks. 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.

READ MOREMarble. Marble is limestone that has been compacted and heated over millions of years. As a result, marble is less porous and slightly stronger than limestone, but still less durable than granite. Depending on the limestone and the mineral combination within the marble, most marble rates from three to five on the Mohs hardness scale.

READ MOREFormally, granite is a plutonic rock that is composed of between 10 to 50% quartz (typically semi-transparent white) and 65 to 90% total feldspar (typically a pinkish or white hue). Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock.
