Fangite is a sulfosalt first discovered in the Mercur gold deposit located in Tooele County Utah. The specimen was found in a boulder in the southern Oquirrh Mountains. The only available specimens of fangite are located in the National Museum of Natural History, Smithsonian Institution. The International Mineralogical Association Commission approved the name Fangite after Dr. Jen-Ho Fang, a crystal chemist affiliated with the University of Alabama, in honor of his significant contributions to crystallography, crystal chemistry, and geostatistics.

==Occurrence== Fangite was detected in an isolated vug of sulfide ore stockpile within the Morrin Hill pit at the Mercur gold deposit. Fangite is associated with subhedral pyrite and fine-grained sulfide indicating partial replacement of pyrite, sphalerite, and other sulfide minerals. Based on surrounding materials, it can be concluded that Fangite forms as a result of alteration of thallium sulfates or by substituting fluids that are Ti-rich for realgar or orpiment.
