Fluid Origin of the Stratabound Fluorite and Celestite ...

The Mesozoic units that outcrop north of Coahuila State in northern Mexico host numerous celestite, celestite-fluorite and fluorite deposits, mainly enclosed in the Cretaceous limestone units. Celestite and celestite-fluorite deposits are lens-shaped bodies, up to 2 m thick and a total length exceeding 500 meters, intercalated within the carbonates of the Cupido Formation (Aptian) or equivalents.

"The Use of Fluorite in Assessing Fluid History and Metal ...

Fluorite is an important gangue mineral as it is ubiquitous throughout the deposit and is used to provide a record of fluid evolution. The complexity of the deposit is apparent from the deposit-scale to micrometer-scale trace-element variations in fluorite crystals such that fluorite is key to understanding the composition of the ore-forming ...
