Unnamed (Zn Sulphite)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
~(Zn,Fe)SO3
As bands within banded sphalerite of carbonate-hosted deposit in Belgium. One of a few mixed/intermediate valence compounds of such deposits, that include subsulphites (see Unnamed (Fe Subsulphite)), sulphites (compare Unnamed (Fe Sulphite)), pyrosulphites (Unnamed (Fe Pyrosulphite)), sulphoxylanes (see Unnamed (Fe Sulphoxylane)), thiosulphates (compare 'UM1995-34-SO:Fe' and Unnamed (Fe Thiosulphate II)). 'UM1995-35-SO:FePb' is also in the list.

These compounds are generally banded/radial/fibrous/spherulitic in form and have lowered reflectivity with growing sulphur valence; they are precursors of the banded sulphide ores.

Sulphite compounds in these deposits are also found as syntaxial intergrowths with disulfides and goethite.

Compare other sulphites, known as approved minerals: albertiniite, scotlandite, gravegliaite, hannebachite.

Locality ListHide

- This locality has map coordinates listed. - This locality has estimated coordinates. ⓘ - Click for references and further information on this occurrence. ? - Indicates mineral may be doubtful at this locality. - Good crystals or important locality for species. - World class for species or very significant. (TL) - Type Locality for a valid mineral species. (FRL) - First Recorded Locality for everything else (eg varieties). Struck out - Mineral was erroneously reported from this locality. Faded * - Never found at this locality but inferred to have existed at some point in the past (e.g. from pseudomorphs).

All localities listed without proper references should be considered as questionable.
