Description
| - The Zn-dominant analogue of rockbridgeite, recently described mineral plimerite, was found in samples from the Huber open pit, the Krasno near Horn Slavkov ore district, western Bohemia, Czech Republic. Plimerite occurs there in five morphologically different types, as black-green to black semi-spherical to spheroidal radiating aggregates (type 1), olive to grey-green aggregates formed by minute tabular crystals (type 2), dark green crystalline aggregates composed of tiny tabular crystals (type 3) and two types (4 and 5) of microscopic aggregates. All plimerite types were found in cavities of strongly altered original triplite accumulations; fluorapatite, isokite, kolbeckite, leucophosphite, beraunite, whitmoreite, kunatite and other rare phosphates were found in the association. Detailed mineralogical data (EPMA, TG, IR, Raman) are given for plimerite type 1. Plimerite from Krasno is orthorhombic, space group Bbmm, with unit-cell parameters a 13.850(1), b 16.798(1), c 5.1581(3) angstrom and V 1200.1(2) angstrom3, Z = 4. The crystal structure was refined by the Rietveld method from the high-resolution synchrotron powder diffraction data to indices Rp 13.57%, Rwp 18.59% and R(Bragg) 13.92% for 140 observed reflections. The refined crystal structure of plimerite from Krasno is related with those of rockbridgeite and of plimerite from Australia; the main differences are connected with the site-occupancies, derived from the site-symmetries and bond-valence parameters.
