Geological and mineralogical information
Formation: The deposits were formed by mineral-rich fluids leached from source rocks by heat from magmatic activity. These fluids then flowed along open spaces and fractures in the earth's crust, depositing minerals as they cooled and their chemistry changed.
Common associations: Barite and fluorite are frequently found together in the same deposits. They can also be associated with other minerals like quartz, galena, cerussite, and wulfenite.
Mineral appearance:
Fluorite: Often found as cubes and can be colorless, yellow, blue, purple, or black.
Barite: Typically forms as white blades or crystals, sometimes accenting the fluorite.
