Name:
The name was introduced by Pasero et al. (2010) for a theoretically, potentially new mineral species, the hydroxyl analogue of hedyphane.
An arsenate apatite supergroup mineral belonging to the hedyphane group. It was approved as a new minerals species by IMA in 2018 (IMA2018-52), and described as a new species by Biagioni et al. (2019).
A fibrous material found at LĂ„ngban, Sweden and called by the local miners as "asbest-hedyphan" was examined by Sjögren (1891). This was probably the first mention of this mineral in the literature. Sjögren concluded that the material consisted of ïŹne-scale intergrowths between a âhydrous magnesium-silicateâ and a âlead-arsenate" (cited after Biagioni et al. 2019).
Later Dunn et al. (1985) described a hedyphane sample from LĂ„ngban, Sweden which contained 0.34 wt % H2O.
