A manganese mine owned by Manganese Ore India, Ltd.

Photos of the blue-violet amphiboles from here are labeled magnesisio-arfvedsonite as this is the dominant species found in these crystals. The amphiboles are however zoned and analyses of individual crystals may show other species.

The tan-yellowish amphiboles from here show a wide range of compositions ranging from mangano-cummingtonite, ferri-ghoseite and ferri-winchite/ferri-katophorite. Some analyses also corresponds to unnamed minerals in the Na-Mn amphibole sub-group. The photos of these amphiboles are labeled ferri-ghoseite, but the specimens may contain a range of amphiboles, where ferri-ghoseite may or may not be one of them.
