Physical Properties of Picrite
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Picrite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Picrite rock are vital in determining its Picrite Texture and Picrite Uses.
Hardness and Strength of Picrite
The physical properties of Picrite 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 Picrite is 6.8 whereas its compressive strength is 189.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Picrite is white, greenish white or grey whereas its fracture is uneven. Luster of Picrite is the interaction of light with the surface of Picrite. Luster of Picrite is subvitreous to dull. Picrite cleavage is imperfect. The specific gravity of Picrite is 2.75-2.92. Picrite is 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.
