WebSome minerals have only one set of cleavage planes, others have two sets, and a few (such as calcite) have three. In minerals with only one or two sets of cleavage planes, some … WebCleavage directions represent planes of weak bonding in the mineral's atomic structure. Because mineral structures are repetitive, a single cleavage often appears as multiple cracks, all parallel. If there is only one direction of atomic weakness, then the mineral may exhibit only one cleavage.
