Synonym: Shape of minerals

Minerals can be in monocrystal form, regular group form or aggregate form. The monocrystal mineral morphology includes the crystal shape, crystal habit, crystal size and striations. The regular group crystal form includes twin crystals, parallel crystals or the external characteristics between various crystals of the mineral. The aggregate morphology refers to the form of minerals of the same class aggregated together, and it hinges on the shape and arrangement of the monocrystals. In general, the morphology of a mineral depends on its internal structure and growth environment. Common mineral aggregates include radiating, stalactitic, reniform, botryoidal, oolitic and pisolitic aggregates (Figs. 25, 26, and 27).
