Species: | 'Sodium-Calcium Amphibole Subgroup' (not an IMA approved species) |
Formula: | An(NaCa)(Z2+5-mZm3+)(Si8-(n+m+1)Al(n+m-1)O22)(OH,F,Cl)2 |
Comments: | 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. |
