reontableite
Reontableite is a hypothetical mineral that has not been officially recognized by the International Mineralogical Association. The term appears to be a neologism, possibly coined for fictional purposes or as a typographical error. There is no scientific literature or mineral databases that list reontableite as a valid mineral species. Its purported properties, composition, or occurrence are therefore not documented in geological or mineralogical resources.
The possibility exists that "reontableite" could be a misspelling of a known mineral, or a term used
