Winchite from
Marinkas Kwela, Karasburg West, ǁKaras Region, Namibia

Species:Winchite
Formula:◻(CaNa)(Mg4Al)(Si8O22)(OH)2
Comments:Prior to the approval of ferri-winchite in 2004, the name winchite was used for both Fe-dominant and Al dominant winchites. As all amphibole from Marinkas Kwelas are Fe-dominant, winchite with its post 2012 nomenclature definition is not present here.
