aliliite

Aliliite is a proposed mineral species name that appears in limited mineralogical discussions as a hypothetical aluminum-rich silicate phase. It has not been recognized as a valid mineral species by the International Mineralogical Association (IMA), and no peer‑reviewed description with a definitive chemical formula, crystal structure, type locality, or physical properties has been published.

The name is derived from the conventional suffix -lite used for minerals and a root suggesting aluminum content (Al). The exact origin of the name varies by author, with some suggesting a derivation from Al for aluminum and a generic mineral suffix.

Because there is no formal description, there is no universally accepted chemical composition or crystallography. In speculative discussions, aliliite is described as an aluminum-rich silicate phase with variable Si:Al ratios, potentially occurring with other silicate or oxide minerals.

Reports of aliliite are scarce and often not accompanied by a verifiable specimen or approved description. No type locality or holotype has been established in the scientific literature.

There are no IMA-recognized publications for aliliite as of this writing. For general context, see the lists of minerals and the -ite suffix in mineralology.
