Properties of Phonolite

Physical Properties of Phonolite

Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Phonolite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Phonolite rock are vital in determining its Phonolite Texture and Phonolite Uses.

Hardness and Strength of Phonolite

The physical properties of Phonolite 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 Phonolite is 5.5-6 whereas its compressive strength is 150.00 N/mm². Streak is the color of rock when it is crushed or powdered. The streak of Phonolite is white whereas its fracture is conchoidal to uneven. Luster of Phonolite is the interaction of light with the surface of Phonolite. Luster of Phonolite is greasy to dull. Phonolite cleavage is poor. The specific gravity of Phonolite is 2.6. Phonolite is translucent to opaque in nature whereas its toughness is not available. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
