WebThe dark color, hardness and well-developed cleavage patterns usually serve to distinguish these minerals from other common rock-forming minerals, with the exception of the pyroxene group. In theory, the two mineral groups can be distinguished by the angle at which their two sets of cleavage planes meet (56 o and 124 o for amphiboles, 87 o and ...
