| Species: | Alforsite |
| Formula: | Ba5(PO4)3Cl |
| Comments: | “Alforsite is.05 mm or smaller grains disseminated in fine-grained metamorphic sanbornite-quartz rock. The alforsite-bearing samples are massive gray rocks with gneissic banding due primarily to segregations of quartz. In prominent bands of pink gillespite, alforsite is associated with sanbornite, witherite, and celsian in quartz-rich and gillespite-rich bands. Fresnoite, walstromite, tourmaline, and pyrite, though less abundant, are disseminated throughout the rock. |
