Leadhillite from
Higher Roughton Gill (Balliway Rigg), Roughton Gill, Caldbeck, Allerdale, Cumbria, England, UK


Classification
Species:Leadhillite
Formula:Pb4(CO3)2(SO4)(OH)2
Comments:Occasionally occurs as pseudomorphs and epimorphs after lanarkite. Green et al. (2008): "Fine lustrous pale yellow leadhillite crystals to 10 mm in the Kingsbury Collection at the NHM are described by Cooper and Stanley (1990). While these may be genuine, they are much larger than any that have been reported since, and given Kingsbury's penchant for claiming old-time specimens from the Leadhills-Wanlockhead district as Caldbeck Fells, they should be treated with caution."
Habit:blocky pseudohexagonal; thin tabular to prismatic.
Confirmation
Validity:Believed Valid
