• The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite.
• Its collection of fluorite crystal specimens is significant, and a reflection of Crittenden County's importance in the history of fluorite mining.
• It is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite.
• Silliman reported in his new American Journal of Science, a publication covering all the natural sciences but with an emphasis on geology, that he had identified tungsten, tellurium, topaz and fluorite in the rocks.
• After exploration, it has been found that tungsten, tin, nickel, antimony, bismuth, antimony, cobalt, molybdenum, copper, lead and zinc, gold, silicon, coal, kaolin, limestone, fluorite, granite, monazite sand Wait for more than 20 minerals.
• There are mineral reserves of gold, iron, coal, steatite, fluorite, and molybdenum, as well as marble and limestone in the northern part of the province.
• Galena typically is found in hydrothermal veins in association with sphalerite, marcasite, chalcopyrite, cerussite, anglesite, dolomite, calcite, quartz, barite, and fluorite.
• Sylvanite is associated with native gold, quartz, fluorite, rhodochrosite, pyrite, acanthite, nagyagite, calaverite, krennerite, and other rare telluride minerals.
• Doped calcium fluoride, like natural fluorite, exhibits thermoluminescence and is used in thermoluminescent dosimeters.
• Additionally, extensive faulting in and around the Shawnee Hills occurred due to deep tectonic activities and formed sites for deposition of fluorite, a mineral used for production of the element fluorine.
• Creedite typically occurs with low-grade metamorphic rocks on a fluorite – calcite – quartz matrix or on a sulfide-matrix with its oxidized products.
• Siderite is commonly found in hydrothermal veins, and is associated with barite, fluorite, galena, and others.
• It is found in hydrothermal veins and contact metamorphic deposits in association with other Cu–Pb–Zn–Ag sulfides and sulfosalts, pyrite, calcite, dolomite, siderite, barite, fluorite and quartz.
• Many EF lenses include such features as Canon's ultrasonic motor (USM) drive, an image stabilization system (IS), diffractive optics (DO) and, particularly for L-series lenses, fluorite and aspherical lens elements.
• It is commonly associated with topaz, cassiterite, wolframite, lepidolite, spodumene, beryl, tourmaline, and fluorite.
• Commonly associated minerals include pyrite, pyrrhotite, galena, sphalerite, fluorite, dolomite, and calcite.
• It was built by the Clay Cross Company to transport minerals such as limestone, fluorite, barytes and gritstone to its works at Clay Cross and for transport around the country by the LMS.
• It occurs associated with cassiterite, arsenopyrite, molybdenite, tourmaline, topaz, rhodochrosite and fluorite.
• Several others plus indium oxide adopt the "C-type rare earth structure", also called "bixbyite", which is cubic and related to the fluorite structure.
• Associated minerals include beryl, phenakite, herderite, tourmaline, muscovite, fluorite and quartz.
