Thick widespread carbonate rock units of the Upper Mississippi River Valley once hosted large amounts of fluorite. These deposits formed as hydrothermal fluids moved along fractures in the carbonate rock, altering or dissolving the carbonate minerals and precipitating a wide variety of metallic ores and pore-filling minerals, including fluorite. . …
Fluorite crystals formed 150–200 million years ago when hot water containing fluorine and other minerals was forced up through cracks in the earth where it interacted with the calcium-rich limestone bedrock. Crystals formed along cracks and in other open spaces in the rock. Fluorite (fluorspar) mining got its start in Illinois in 1842.
