Augite typically forms elongated prismatic crystals with a square or octagonal cross-section. These crystals may exhibit cleavage along two directions forming angles of nearly 90 degrees.
Augite is primarily found in extrusive igneous rocks, such as basalt and andesite. It forms from the rapid cooling of magma at or near the Earth's surface, which allows for the development of its characteristic pyroxene crystal structure. While augite can also occur in some intrusive rocks, its predominant association is with extrusive environments.
minerals get its crystal shape by the heating and pressure from rock
Yes, crystal shape is a physical property. It refers to the external geometric form that a crystal takes, which is determined by the arrangement of atoms within the crystal lattice. The shape of a crystal can provide information about its internal structure and symmetry.
When a mineral forms a definite shape, it is known as a crystal. Crystals are ordered arrangements of atoms or ions in a repeating pattern that gives them their characteristic shape. Crystal shape is determined by the internal arrangement of atoms within the mineral.
Gold does not have a defined crystal shape as it is a metallic element. However, under certain conditions, gold can form cubic, octahedral, or dodecahedral crystal shapes.
Augite rocks have a medium to coarse-grained texture. They typically appear as dark green to black minerals with a prismatic crystal shape, giving them a somewhat rough appearance.
Augite typically exhibits a vitreous to dull luster, depending on its specific composition and crystal structure.
Examples of ferromagnesian silicate minerals include olivine, pyroxenes (such as augite), amphiboles (such as hornblende), and biotite mica. These minerals contain iron and magnesium in their crystal structures, which contribute to their dark color and magnetic properties.

Crystal Symmetry is the ability of a crystal to shape by nature and has a symmetrical shape. It's also referred about the occupation of diamond cutters.
