What is the difference between fracture and cleavage in a mineral?
Cleavage = breaks along flat, smooth planes into a set shape,
Fracture = breaks in random, jagged edges.
Cleavage = breaks in random, jagged edges.
Fracture = breaks along flat, smooth planes into a set shape,
Fracture or cleavage of a mineral is determined by:
how long it took to form
the internal arrangement of atoms
temperature
the color of the mineral
