Mn2+Fe2+5MgSi8O22(OH)2 |
Bedded Mn deposit at Yokoneyama. At the Suishoyama pegmatite the mineral is mixed with clinoamphiboles. |
Approved IMA 1986 (Dana # Added) |
Yokoneyama, Tochigi Prefecture, Japan. Siushoyama, Fukushima Prefecture, Japan. Link to MinDat.org Location Data. |
The name indicates the structural relationship to protoamphiboles, and the compositional relationship to protoferro-anthophyllite and anthophyllite. |
