WebCleavage / fracture. Cleavage and fracture describe different ways in which a mineral can break. Definitions. Cleavage - The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between … WebThe common Garnets can be divided into two subgroups: Group 1: Garnets containing aluminum (Al) as their second element. These include Pyrope, Almandine, and Spessartine. ("Pyralspite") Group 2: Garnets containing calcium (Ca) as their first element. These include Uvarovite, Grossular, and Andradite . ("Ugrandite")
