The Jbel Tirremi fluorite-barite ± sulfide deposit in northeastern Morocco is hosted in a Jurassic-aged structurally high carbonate platform known as the Jbel Tirremi dome. The host rocks consist of unmetamorphosed, flat-lying early Jurassic dolomitized limestones, locally intruded by Eocene lamprophyre dikes.

Barite is a mineral composed of barium sulfate (BaSO4) and derives its name from the Greek word 'barys', meaning "heavy.". This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. Barite is typically white/grey in appearance but can vary from yellow, brown, red, and even black due to ...

Barite is the main ore of the element barium. It is also important in the manufacture of paper and rubber. Barite is also used in radiology for x-rays of the digestive system. When crushed, it is added to mud to form barium mud, which is poured into oil wells during drilling. A rich, white pigment was once made from crushed Barite.
