    Igneous rocks (Granites). Igneous rocks are formed by the crystallisation of a magma. The difference between granites and basalts is in silica content and their rates of cooling. A basalt is about 53% SiO2, whereas granite is 73%. Intrusive, slowly cooled inside the crust. (Plutonic rock = formed in the earth). Large crystals.
