Properties of Marl

Physical Properties of Marl

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

Hardness and Strength of Marl

The physical properties of Marl 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 Marl is 2-3 whereas its compressive strength is 30.00 N/mm². Streak is the color of rock when it is crushed or powdered. The streak of Marl is white whereas its fracture is conchoidal. Luster of Marl is the interaction of light with the surface of Marl. Luster of Marl is dull. Marl cleavage is . The specific gravity of Marl is 2.2-2.8. Marl is opaque in nature whereas its toughness is 2.6. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
