Species: | 'Planerite-Turquoise Series' (not an IMA approved species) |
Comments: | Originally reported to be coeruleolactite. All purported coeruleolactite examined by the authors of the 1998 report (Foord, E.E. & Taggart, J.E.) were largely Planerite, or Occasionally turquoise. Published analysis indicates that the vacany in the 'A' site is between 0.51-0.54 atom fraction, the balance in Cu-0.40 and Zn-0.06 to 0.09. It is suggested by this analysis that the turquoise structure likely cannot accomodate Ca in the 'A' site. |
