Detailed Mineral List:

ⓘ Aegirine-augite
Formula: (NaaCabFe2+cMgd)(Fe3+eAlfFe2+gMgh)Si2O6
ⓘ Aegirine-augite var. Blanfordite
Formula: (Na,Ca)(Fe3+,Fe2+,Mn,Mg,Al)Si2O6
ⓘ 'Biotite'
Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg/Ti)([Si/Al/Fe]2Si2O10)(OH/F)2
ⓘ 'Biotite var. Manganophyllite'
Formula: K(Fe,Mg,Mn)3AlSi3O10(OH)2
ⓘ 'Feldspar Group'
ⓘ Quartz
Formula: SiO2
ⓘ 'Sodium-Calcium Amphibole Subgroup'
Formula: An(NaCa)(Z2+5-mZ3+m)(Si8-(n+m+1)Al(n+m-1)O22)(OH,F,Cl)2
Description: Sathe et. al (1965) published the amphibole from the Goldongri mine as winchite. Their analysis show some anomalies, as Ʃ(Si+Al) < 8, ƩC position<5 and ƩA position >1. Based on a moderate Ca content and a high Na content it is likely that the amphibole analysed by Sathe et. al (1965) belongs to the Sodium-Calcium Amphibole Subgroup.
ⓘ Winchite
Formula: ◻{CaNa}{Mg4Al}(Si8O22)(OH)2
Description: The identification of winchite from the Goldongri Mine was based on a general consensus at the time that all violet amphiboles from the Indian metamorphic manganese ores (gondites) was winchite. Later microprobe analyses show a variety of compositions, mostly corresponding to magnesio-arfvedsonite.
