Irregular shaped crystals of indeterminate crystalline form. Anhedral crystals grew in an impeded environment, such as adjacent to simultaneously growng crystals, producing a material whose characteristics used to determine crystalline form, such as plane faces, are not visible. In a rock where most of the grains are anhedral, the fabric is said to be allotriomorphic granular.
