description Clinozoisite Overview
Clinozoisite is a calcium aluminium silicate hydroxide mineral in the epidote group. It is the monoclinic polymorph of zoisite, so it has the same chemical composition as zoisite but a different crystal structure. It forms mainly in metamorphic rocks and occurs in colors including green, yellow, grey, and pink. Transparent pieces are uncommon and may be faceted for collectors, but most clinozoisite is kept as a mineral specimen.
help Clinozoisite FAQ
What is clinozoisite made of?
Clinozoisite is a calcium aluminium silicate hydroxide mineral in the epidote group. It has the same chemical composition as zoisite, but its crystal structure is different.
How is clinozoisite different from zoisite?
Clinozoisite is the monoclinic polymorph of zoisite, while zoisite has a different crystal structure. The two minerals can therefore share chemistry while forming different crystal habits.
Where does clinozoisite form?
Clinozoisite forms mainly in metamorphic rocks, where heat and pressure alter existing minerals. It commonly occurs in rocks affected by regional or contact metamorphism.
What colors can clinozoisite be?
Clinozoisite can occur in several colors, including green, yellow, gray, brown, and pinkish tones. Its color depends on trace elements and the conditions under which the mineral formed.
