Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Trondhjemite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Trondhjemite rock are vital in determining its Trondhjemite Texture and Trondhjemite Uses.
The physical properties of Trondhjemite 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 Trondhjemite is 6-7 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Trondhjemite is bluish black whereas its fracture is conchoidal. Luster of Trondhjemite is the interaction of light with the surface of Trondhjemite. Luster of Trondhjemite is subvitreous to dull. Trondhjemite cleavage is not available. The specific gravity of Trondhjemite is 2.86-3. Trondhjemite is opaque in nature whereas its toughness is 2.1. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
