    Description: 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.

    Description: Has XRD pattern similar to tourmaline, but is not dense enough and XRD can not be used to identify tourmaline species. Extremely unlikely occurrence of a ferric tourmaline in a granite pegmatite. The statements in Min Rec. 33:215 are insufficient to accept this identification. Optics, specific gravity, and "gemological techniques" can not be accepted as conclusive proof. Quantitative chemical analyses are necessary.

    Description: Tiny yellow crystals on spherical stokesite crystal aggregates. Note: Only one specimen of stannomicrolite has been verified from this location to date. Many specimens were subsequently distributed with the same description, but have not yeilded the chemical analysis and were either normal microlite or uranmicrolite. (Luis Menezes, pers. com., 2009).
