These smooth planes are parallel to zones … WebSep 24, 2024 · How do you identify cleavage and fracture? Background: Cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. Fracture is the property of a mineral breaking in a more or less random pattern with no smooth planar …
