A mineral has no particular planes of weakness in its lattice structure, so it does not break along particular planes.

Question

What happens when this mineral is struck?

Answer 1

When this mineral is struck, it will undergo fracture rather than cleavage. Since it does not have particular planes of weakness in its lattice structure, the mineral will break irregularly and without a specific pattern, resulting in fracture. This means that the mineral will shatter into irregular pieces rather than breaking along distinct planes.
