About Ferri-winchiteHide

Formula:
☐[CaNa][Mg4(Fe3+,Al)]Si8O22(OH)2
The winchite-group minerals are defined as sodium-calcium amphiboles with A(Na+K+ 2Ca)<0.5 apfu and with C(Al+Fe3++2Ti)<1.5 apfu. The W position may contain (OH), F or Cl.

Ferri-winchite is defined with
C2+ position: Mg dominant

A piece of blueschist matrix often called "Crossite" was personally collected and analyzed by David Lowe. It contained Ferri-Winchite matching reference XRD pattern PDF 00-052-1577 and Albite PDF 01-084-0752. It was in direct contact with Neptunite, which was separately found to match PDF 00-043-0677. No other crystalline phases were found.
