The infrared and Raman spectra of cerussite have been assigned according to the vibrational symmetry species. The assignment of satellite bands to 18O isotopes has been discussed with respect to the use of these bands to the quantification of the isotopes. Overtone and combination bands have been assigned according to symmetry species and their corresponding fundamental vibrations. The vibrational spectra of cerussite have been compared with other aragonite group minerals and the differences explained on the basis of differing chemistry and crystal structures of these minerals. The single crystal spectra of natural erythrite has been reported and compared with the synthetic equivalent. The symmetry species of the vibrations have been assigned according to single crystal and factor group considerations. Deuteration experiments have allowed the assignment of water vibrational frequencies to discrete water molecules in the crystal structure. Differences in the spectra of other vivianite arsenates, namely annabergite and hörnesite, have been explained by consideration of their differing chemistry and crystal structures. A novel approach to the assignment of site occupancy of ions in the erythrite – annabergite solid solution has been reported. This approach has utilised vibrational spectroscopy, in conjunction with careful consideration of the crystal structures of the minerals. It has been shown that in the erythrite – annabergite solid solution Co 5 prefers metal site 2 contrasting nickel which prefers site 1. This study in conjunction with other studies has yielded the trend that the more electronegative metal prefers to occupy site 1, with the least electronegative metal preferring to occupy site 2. Fundamentally this thesis has increased the knowledge base of the spectroscopic properties of the aragonite and the vivianite minerals. The site occupancy of metal ion substitutions in solid solution series of the vivianite group of minerals has been further enhanced, with novel method of studying the site occupancy of ions in solid solutions has been developed. A detailed knowledge and understanding of factor group analysis applied to the study of minerals has been achieved. 6 PUBLICATIONS WRITTEN IN THE COURSE OF STUDY 1.

    MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky.

Churakov 1,2 1 Institute of Geological Sciences, University of Bern, Baltzerstrasse 3, CH-3012 Bern, Switzerland; [email protected] (T.A.); [email protected] (S.V.C.) 2 Laboratory for Waste Management, Paul Scherrer Institute, Forschungsstrasse 111, CH-5232 Villigen, Switzerland * Correspondence: [email protected] Abstract: The thermodynamic properties of carbonate minerals suggest a possibility for the use of the abundant materials (e.g., magnesite) for removing harmful divalent heavy metals (e.g., Pb2+). Despite the favourable thermodynamic condition for such transformation, batch experiments performed in this work indicate that the kinetic of the magnesite dissolution at room temperature is very slow. II Another set of co-precipitation experiments from homogenous solution in the Mg-Pb -CO2-H2O system reveal that the solids formed can be grouped into two categories depending on the Pb/Mg ratio. The atomic ratio Pb/Mg is about 1 and 10 in the Mg-rich and Pb-rich phases, respectively. Both phases show a significant enrichment in Pb if compared with the initial stoichiometry of the aqueous solutions (Pb/Mg initial = 1 × 10−2 − 1 × 10−4). Finally, the growth of {10.4} magnesite surfaces in the absence and in the presence of Pb2+ was studied by in situ atomic force microscopy (AFM) measurements. In the presence of the foreign ion, a ten-fold increase in the spreading rate of the obtuse steps was observed.

Cerussite / PbC03 / Neutron structure refinement / Aragonite-type carbonates Abstract. The crystal structure of cerussite, PbC03, was refined with 669 merged single-crystal neutron data [Fo > 3G(Fo)]to R = 0.032, Rw = 0.Of5 (space group Pmcn; a = 5.179(1), b = 8.492(3), c = 6.141(2); Z = 4). - Cerussite belongs to the aragonite-type compounds. The weak aplanarity of the carbonate group, d = 0.026(1) A, is of the same order of magnitude as in aragonite, CaC03, and strontianite, SrC03, and the direction of the deviation from planarity is the same. The minor details of the stereochemistry differ slightly from the expectations to be drawn from the structures of the alkaline earth carbonates on the basis of the effective ionic radii of the twovalent metals. Introduction It is well known from the old days of morphological crystallography that cerussite, PbC03, is isomorphous with aragonite, CaC03, strontianite, SrC03, and witherite, BaC03. Zachariasen (1928) confirmed this by X-ray methods and derived coordinates of the Pb atom for this mineral.

    MINERALOGICAL MAGAZINE, MARCH 1983, VOL. 47, PP. 51 7 Infrared spectroscopic analysis of the olivenite- adamite series, and of phosphate substitution in olivenite R. S. W. BRAITHWAITE Chemistry Department, University of Manchester Institute of Science and Technology, Manchester, M60 1QD ABSTRACT. Infrared spectroscopy affords a rapid and Inspection of the infrared spectra of a number of easy method of estimating the position of a mineral in the natural samples suggested that infrared spectro- olivenite-adamite solid solution series, and of estimating scopy might afford a rapid and easy method for the amount of phosphate substitution in olivenites. placing the approximate position of a small sample Toman's discovery of the monoclinic symmetry of olivenites with up to approximately 20 atom ~ Zn/(Cu + in the olivenite-adamite series and for estimating Zn) has raised a problem in nomenclature. It is suggested the amount of anion substitution by phosphate. that the definition of'cuproadamite' be extended to cover Accordingly, numerous members of the olivenite- all orthorhombic members of the series containing adamite series were synthesized by the method used appreciable Cu. Studies of deuterated materials have by Guillemin (t956), Minceva-Stefanova et al. helped to solve some of the absorption band assignments (1965), and Toman (1978). In addition, the method for olivenite adamite, libethenite and related minerals. was extended to the preparation of phosphatian olivenites, libethenite, and some deuterated MEMBERS of the olivenite Cu2AsO4OH to adam- materials, required in order to distinguish vibra- ite Zn2AsO4OH solid solution series are well- tions involving O H from other vibrations (see known minerals from the oxidation zone of Cu- Experimental section).

  • Formation of Chrysocolla and Secondary Copper Phosphates in the Highly Weathered Supergene Zones of Some Australian Deposits
    Records of the Australian Museum (2001) Vol. 53: 49–56. ISSN 0067-1975 Formation of Chrysocolla and Secondary Copper Phosphates in the Highly Weathered Supergene Zones of Some Australian Deposits MARTIN J. CRANE, JAMES L. SHARPE AND PETER A. WILLIAMS School of Science, University of Western Sydney, Locked Bag 1797, Penrith South DC NSW 1797, Australia [email protected] (corresponding author) ABSTRACT. Intense weathering of copper orebodies in New South Wales and Queensland, Australia has produced an unusual suite of secondary copper minerals comprising chrysocolla, azurite, malachite and the phosphates libethenite and pseudomalachite. The phosphates persist in outcrop and show a marked zoning with libethenite confined to near-surface areas. Abundant chrysocolla is also found in these environments, but never replaces the two secondary phosphates or azurite. This leads to unusual assemblages of secondary copper minerals, that can, however, be explained by equilibrium models. Data from the literature are used to develop a comprehensive geochemical model that describes for the first time the origin and geochemical setting of this style of economically important mineralization.
