Hedleyite from
Clogau St Davids Mine (Clogau Mine; St David's Mine), Llanelltyd, Gwynedd, Wales, UK


Locality type:Mine
Classification
Species:Hedleyite
Formula:Bi7Te3
Comments:Hedleyite occurs as tiny inclusions in galena on a specimen (K3) in the Kingsbury Collection held at the Natural History Museum, London (Naden, 1988). This, the Uk's first occurrence, is the only known specimen from Clogau Mine. No other examples have come to light despite extensive studies (National Museum of Wales database).

Whilst confirmed analytically, the occurrence should be treated with caution due Kingsbury's known creative specimen provenancing practices (Ryback et al., 1998).
Confirmation
Validity:Believed Valid
