Physical Properties of Pegmatite
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Pegmatite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Pegmatite rock are vital in determining its Pegmatite Texture and Pegmatite Uses.
Hardness and Strength of Pegmatite
The physical properties of Pegmatite depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Pegmatite is 7 whereas its compressive strength is 178.54 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Pegmatite is white whereas its fracture is conchoidal. Luster of Pegmatite is the interaction of light with the surface of Pegmatite. Luster of Pegmatite is grainy, pearly and vitreous. Pegmatite cleavage is perfect. The specific gravity of Pegmatite is 2.6-2.63. Pegmatite is translucent to opaque in nature whereas its toughness is 2.1. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
