Physical Properties of Dacite
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Dacite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Dacite rock are vital in determining its Dacite Texture and Dacite Uses.
Hardness and Strength of Dacite
The physical properties of Dacite 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 Dacite is 2-2.25 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Dacite is white whereas its fracture is conchoidal. Luster of Dacite is the interaction of light with the surface of Dacite. Luster of Dacite is subvitreous to dull. Dacite cleavage is perfect. The specific gravity of Dacite is 2.86-2.87. Dacite is translucent 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.
