| Malleable - Deforms rather than breaking apart with a hammer. | |||
| Exsolution Inclusions - Formed by the exsolution of a separate mineral from the parent mineral caused by a temperature drop. | |||
| Granular - Generally occurs as anhedral to subhedral crystals in matrix. | |||
| Massive - Granular - Common texture observed in granite and other igneous rock. | |||
