Fluorite

Taourirt Complex, Taourirt Province, Oriental Region, Morocco

7×6,5×6 cm.

Multi stepped crystallized cubic Fluorite with good luster, translucent to transparent appearance, and beautiful lilac color which gradually intensifies from top to bottom; the black patina present at the bottom is probably due to a metallic sulfide.

Normally specimens coming from this classic mine are not so excellent in quality but this piece displays a nice aesthetic and can be considered highly representative.

– Abstract – The Jbel Tirremi Fluorite-Barite deposit, located in the Taourirt region (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. The orebodies consist mostly of Fluorite and Barite, and occur as open-space fillings and partial to massive replacement of the enclosing medium- to coarse-grained dolomitized limestones. The ore mineralogy is dominated by Fluorite of different colors and habits, Barite, and, to a lesser extent, Sulfides. The Fluorite and Barite mineralization are petrogenetically unrelated, pointing instead to the regional circulation of hydrothermal basinal brines mixed to various degrees with meteoric water.
