It occurs in regionally metamorphosed rocks, such as schists and hornfels, and in contact metamorphic aureoles. Significant deposits exist in South Africa, Spain, France, and the USA.

The standard pronunciation is /ˌændəˈluːsaɪt/ (an-duh-LOO-site), with the primary stress on the third syllable.

Chiastolite is a variety of andalusite containing distinctive cross-shaped inclusions of carbon, making it popular with collectors and for ornamental uses.

A grey, green, brown, or pink aluminium silicate mineral, often found in metamorphic rocks, crystallizing in an orthorhombic system.
