Galena's cleavage is cubic.
It has both. It's cleavage is perfect, and it's fracture is sub-conchoidal.
The property that causes galena to break into tiny cubes is its cleavage. Galena exhibits perfect cubic cleavage, meaning that when struck or broken, it tends to break along smooth, flat planes that are parallel to the cube faces of the crystal structure.
Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
azurite is one of the minerals that has a light blue streak.
Galena breaks into tiny cubes due to its crystal structure, which is cubic. When it fractures, it tends to break along its natural cleavage planes, resulting in the formation of small cube-shaped fragments.

Galena is an interesting ore of lead (lead sulfide). It can form in isometric crystals and has perfect 4 direct cleavage forming cubes.
