Pegmatite Properties

Pegmatite properties are essential when it comes to identification of rocks. The study of properties of Pegmatite rock is done by Mineralogists to determine the identity of rock. Some of the properties of Pegmatite include: Hardness, Color, Fracture, Luster, Compressive Strength etc. Pegmatite is Medium to Coarse Grained. As compared to other rocks, Pegmatite is more porous and its density is 2.6-2.65 g/cm3. Get to know more about physical properties of Pegmatite and thermal properties of Pegmatite.

Physical Properties of Pegmatite

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

Hardness and Strength of Pegmatite

The physical properties of Pegmatite 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 Pegmatite is 7 whereas its compressive strength is 178.54 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Pegmatite is white whereas its fracture is conchoidal. Luster of Pegmatite is the interaction of light with the surface of Pegmatite. Luster of Pegmatite is grainy, pearly and vitreous. Pegmatite cleavage is perfect. The specific gravity of Pegmatite is 2.6-2.63. Pegmatite is translucent to 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.

Thermal properties of Pegmatite

Check out more about What Is Pegmatite and its thermal properties. Thermal properties of Pegmatite play an important role in geology. Specific heat capacity, resistance offered by the rock to heat, water, pressure etc. are some of the thermal properties of Pegmatite.

Specific Heat Capacity of Pegmatite

Specific heat capacity is defined as the heat capacity per unit mass of rock. Specific heat capacity or specific heat is one of the important properties of Pegmatite. The specific heat capacity of Pegmatite is Not Available. Properties of Pegmatite also include resistance of Pegmatite to heat, water, pressure, impact etc. It helps in determining the parameters to which Pegmatite offers resistance. If we talk about Pegmatite resistance, Pegmatite is heat resistant, impact resistant, pressure resistant.
