Pyromorphite from
Torr Works Quarry, Cranmore, Mendip, Somerset, England, UK
| Locality type: | Quarry | |
| Classification | ||
|---|---|---|
| Species: | Pyromorphite | |
| Formula: | Pb5(PO4)3Cl | |
| Comments: | A considerable number of supposed specimens of 'pyromorhpite' from Merehead were analysed, and invariably proved to be greenish coloured mimetite. Pyromorphite does not occur at this location. Recent work by soil scientists (see references in Turner and Rumsey (2010) have shown that Mn++ destabilises the pyromorphite structure and prevents its formation. This fact almost certainly explains the absence of pyromorphite within the manganese-oxide hosted deposits. | |
