Granite. Granite is the most widespread of igneous rocks, underlying much of the continental crust. Granite is an intrusive igneous rock. Intrusive rocks form from molten material (magma) that flows and solidifies underground, where magma cools slowly. Eventually, the overlying rocks are removed, exposing the granite.

The Density of Common Rocks and Minerals

 · 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.
