Physical Properties of Blueschist
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Blueschist like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Blueschist rock are vital in determining its Blueschist Texture and Blueschist Uses.
Hardness and Strength of Blueschist
The physical properties of Blueschist 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 Blueschist is 3.5-4 whereas its compressive strength is 220.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Blueschist is white to grey whereas its fracture is conchoidal. Luster of Blueschist is the interaction of light with the surface of Blueschist. Luster of Blueschist is dull. Blueschist cleavage is slaty. The specific gravity of Blueschist is 3-3.2. Blueschist is opaque in nature whereas its toughness is 1.5. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
