Physical Properties of Migmatite
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Migmatite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Migmatite rock are vital in determining its Migmatite Texture and Migmatite Uses.
Hardness and Strength of Migmatite
The physical properties of Migmatite 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 Migmatite is 5.5-6.5 whereas its compressive strength is 120.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Migmatite is white whereas its fracture is irregular. Luster of Migmatite is the interaction of light with the surface of Migmatite. Luster of Migmatite is dull to pearly to subvitreous. Migmatite cleavage is . The specific gravity of Migmatite is 2.65-2.75. Migmatite is opaque in nature whereas its toughness is 1.2.
