| Potassic-fluoro-richterite ? | ||
| Formula: | {K}{CaNa}{Mg5}(Si8O22)(F,OH)2 | |
| Description: | A Rob Lavisnky specimen from "Kokcha Valley" was later reclassified as winchite (pers. comm. of Rob Lavinsky to Olav Revheim). This does not preclude the occurrence of fluoro-potassicrichterite at Sar-e Sang, but indicates that proper analyses have to be carried out on each single amphibole specimen to reveal its true identity. | |
