Physical Properties of Phyllite
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Phyllite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Phyllite rock are vital in determining its Phyllite Texture and Phyllite Uses.
Hardness and Strength of Phyllite
The physical properties of Phyllite 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 Phyllite is 1-2 whereas its compressive strength is 50.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Phyllite is white whereas its fracture is conchoidal. Luster of Phyllite is the interaction of light with the surface of Phyllite. Luster of Phyllite is phyllitic. Phyllite cleavage is crenulation and pervasive. The specific gravity of Phyllite is 2.72-2.73. Phyllite is opaque in nature whereas its toughness is 1.2. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
