What property of a mineral indicates that it has cleavage?
Just so, what is the cleavage of a mineral?
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding. Fracture is the tendency of a mineral to break along curved surfaces without a definite shape. These minerals do not have planes of weakness and break irregularly.
Also Know, what are the 7 physical properties of minerals? Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
Similarly, you may ask, what causes a mineral to have the properties that it has?
Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.
What are the 3 cleavage planes?
Types of cleavage
- Basal or pinacoidal cleavage occurs when there is only one cleavage plane.
- Cubic cleavage occurs on when there are three cleavage planes intersecting at 90 degrees.
- Octahedral cleavage occurs when there are four cleavage planes in a crystal.
