| Comments: | Green et al. (2008): "In April 2005 a number of specimens displaying rich felted aggregates and masses of acicular pale green crystals on calcite and baryte, partially filling cavities in a ferruginous dolomite vein, were collected from an access road approximately two thirds the way down the quarry at its western end (well away from the original copper occurrence). Analyses produced a tangeite-like XRD pattern (XRD reference number MANCH: XRDI440), while EDS showed that copper, vanadium, calcium, and lead were the major elements present with an atomic number greater than 10. This is sufficient to identify the specimens as lead-rich tangeite.
Although the crystal habit of tangeite can mimic the tabular pseudo-hexagonal habit of vésigniéite and volborthite (e.g. Anthony, J.W., Bideaux, R.A, Bladh, KW. and Nichols, M.C. (2000) Handbook of Mineralogy, volume IV: arsenates, phosphates, vanadates. Mineral Data Publishing, Tucson, Arizona.), it occurs as distinctive felted masses in the specimens we have examined from New Cliffe Hill Quarry. These are not unlike some of the early material from the type locality in Kyrgyzstan (Pekov, I.V. (1998) Minerals first discovered on the territory of the former Soviet Union. Ocean Pictures,
Moscow.). The specimens from New Cliffe Hill Quarry are remarkably rich and it is unfortunate that they seem to have been wetted before they were collected. Although the XRD pattern is not a perfect match for tangeite, this is not unusual (again due to preferred orientation) in material with a fibrous or acicular crystal morphology. The presence of lead, probably substituting for calcium, is also likely to affect the crystal structure (and hence the XRD data). This type of substitution does not appear to have been reported previously, but unfortunately, the fibrous crystal morphology, with crystals typically much less than a micrometre across, made preparation of samples for quantitative analysis by WDS extremely difficult and no useful data was collected. It is clear from inspection of the EDS spectra that calcium is present at a greater concentration than lead and it can, therefore, be described as a lead-rich tangeite." |
