Physical Properties of Hornfels
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Hornfels like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Hornfels rock are vital in determining its Hornfels Texture and Hornfels Uses.
Hardness and Strength of Hornfels
The physical properties of Hornfels 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 Hornfels is 2-3 whereas its compressive strength is 5.80 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Hornfels is unknown whereas its fracture is conchoidal. Luster of Hornfels is the interaction of light with the surface of Hornfels. Luster of Hornfels is shiny. Hornfels cleavage is perfect. The specific gravity of Hornfels is 3.4-3.9. Hornfels is opaque in nature whereas its toughness is not yet found.
