Species: | Azurite |
Formula: | Cu3(CO3)2(OH)2 |
Comments: | Green et al. (2008): "An azurite specimen in the R. J. King collection at the National Museum Wales, with crystals up to 15 mm long, is reputed to be from higher Roughton Gill (Cooper and Stanley, 1990). If genuine it is by far the best example of the species from the Caldbeck Fells. No similar specimens have ever been found, and the history of the specimen, which was obtained from an old collection by the north-of-England mineral dealer W. F. Davidson, is sufficiently uncertain that we consider the occurrence remains unproven. The presence of large crystals of azurite, a mineral which requires a relatively high partial pressure of CO2 to crystallise, is geochemically unlikely in the Caldbeck Fells." |
