Unnamed (Fe Thiosulphate II)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Fe5S5O8 or FeSO2
Crystal System:
Orthorhombic
Occurs as relatively large inclusions (up to 200 microns in size) within banded pyrite/marcasite from Bleiberg, Austria. May occur in a mixture with pyrite.

Compare viaeneite, UM1995-34-SO:Fe, UM1995-35-SO:FePb, Unnamed (Fe Subsulphite), sulphites (Unnamed (Fe Sulphite), Unnamed (Zn Sulphite), albertiniite), pyrosulphites (Unnamed (Fe Pyrosulphite)), sulphoxylanes (Unnamed (Fe Sulphoxylane)) and Unnamed (Fe Oxysulphide).

Compare albertiniite - a sulphite mineral.
