Ferro-ferri-winchite from
Harstigen Mine, Pajsberg, Persberg ore district, Filipstad, VĂ€rmland County, Sweden


Locality type:Mine
Classification
Species:'Ferro-ferri-winchite' (not an IMA approved species)
Formula:◻[CaNa][Fe42+(Fe3+,Al)]Si8O22(OH)2
Comments:Old samples before 1994 were labelled as "radial actinolite (radialstrÄlig aktinolit).

It occurs fairly abundantly in a restricted association, consisting of a dark green clinopyroxene intergrown with fine-grained hematite and yellowish-brown andradite. This matrix is
cut by distinctly later veinlets of rhodonite, occurring as euhedral crystals embedded in fibrous to radiating ferro-ferri-winchite and minor baryte, galena, and calcite."
Habit: actinolite-like spherical aggregates up to 5 mm in size
Confirmation
Validity:Believed Valid
Associated Minerals:
Associates:Andradite
Baryte
Calcite
Clinopyroxene Subgroup
Galena
Hematite
Rhodonite
