Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Gabbro like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Gabbro rock are vital in determining its Gabbro Texture and Gabbro Uses.
The physical properties of Gabbro 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 Gabbro is 7 whereas its compressive strength is 225.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Gabbro is black whereas its fracture is conchoidal. Luster of Gabbro is the interaction of light with the surface of Gabbro. Luster of Gabbro is not available. Gabbro cleavage is not available. The specific gravity of Gabbro is 2.86-2.87. Gabbro is opaque in nature whereas its toughness is 1.6. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
