Cloudite

Chemical formula: BaFe<sup>3+</sup><sub>3</sub>(PO<sub>4</sub>)(S<sup>6+</sup>O<sub>4</sub>)(OH)<sub>6</sub>

Cloudite is a hypothetical mineral with the formula BaFe³⁺₃(PO₄)(SO₄)(OH)₆, whose existence has not been confirmed.

## Characteristics Cloudite is a name not approved by the International Mineralogical Association (IMA) for a hypothetical mineral. The given chemical formula BaFe³⁺₃(PO₄)(SO₄)(OH)₆ would classify it in the alunite supergroup, specifically in the beudantite subgroup. Structurally, it would be the barium and phosphate analogue of other minerals in this group. To date, no natural material with this composition has been discovered or described in scientific literature. ## Physical Properties Physical properties are unknown, as the mineral has not been discovered in nature. ## Colors and Varieties Unknown. ## History and Name The name "Cloudite" is not officially recognized and has no documented history or etymology in mineralogical literature. ## Applications None.

Trigonal

Diagnostic features

## Identification Since the mineral has not been formally described, there are no diagnostic features for it. Identification would require advanced analytical methods (e.g., XRD, EDS) to confirm its unique structure and chemical composition. ## Distinguishing from Similar Minerals Theoretically, distinguishing it from other members of the beudantite group (e.g., corkite, weilerite) would only be possible based on detailed chemical analysis showing the simultaneous dominance of barium at the cation site and the phosphate group. ## Crystal Forms Unknown. Based on its structural affiliation with the alunite supergroup, trigonal crystals, possibly in the form of small rhombohedra, could be expected.

Geological environment

## Genesis Unknown. Other minerals from the beudantite group form in the oxidation zones of ore deposits as secondary minerals. ## Mineral Associations Unknown. ## Localities No confirmed localities worldwide.

Rarity

Extremely rare

For collectors

## Quality Criteria Not applicable, as the mineral is unconfirmed.

Care and storage

## Cleaning Information unavailable due to the lack of natural material. ## What to Avoid Information unavailable. ## Storage Information unavailable.
