Pegmatite properties are essential when it comes to identification of rocks. The study of properties of Pegmatite rock is done by Mineralogists to determine the identity of rock. Some of the properties of Pegmatite include: Hardness, Color, Fracture, Luster, Compressive Strength etc. Pegmatite is Medium to Coarse Grained. As compared to other rocks, Pegmatite is more porous and its density is 2.6-2.65 g/cm3. Get to know more about physical properties of Pegmatite and thermal properties of Pegmatite.
