Vermikuliitin is a term that has appeared in some speculative or informal sources to refer to a hypothetical vermiculite-derived hydrated layered silicate. It is not recognized as a mineral by the International Mineralogical Association, and there is no widely accepted formal definition or chemical formula for the substance.
In proposed descriptions, vermikuliitin would be a 2:1 phyllosilicate—a layered silicate consisting of silicate tetrahedral sheets
Occurrence and nomenclature for vermikuliitin are not standardized. Some discussions treat it as a laboratory-derived or
Potential applications are likewise speculative and confined to research contexts. If vermikuliitin were to exist as
