Metallogenesis of Germanium—A Review ⁎ R

Schroll c a Department für Geo-und Umweltwissenschaften, Sektion Geologie, LMU München, Luisenstrasse 37, D-80333 München, Germany b Department für Geo-und Umweltwissenschaften, Sektion Mineralogie, Petrologie und Geochemie, LMU München, Theresienstrasse 41, D-80333 München, Germany c Institut für Mineralogie und Kristallographie, Universität Wien, Althanstrasse 14, A-1090 Wien, Austria Received 5 November 2002; accepted 23 July 2005 Available online 15 June 2006 Abstract Germanium (Ge) is a scarce, but not an extremely rare element in the Earth's crust (about 1.6 ppm Ge crustal average). Principal geochemical substitutions and mineral associations of Ge include Si, C, Zn, Cu, Fe, Sn, and Ag. Most Ge is dispersed through silicate minerals due to the substitution of Ge4+ for the geochemically similar Si4+. Ge is unusual in that it exhibits siderophile, lithophile, chalcophile and organophile behaviour in different geologic environments. Only minor variations in Ge concentrations are known from different igneous rocks, siliceous sedimentary rocks, and their metamorphic equivalents. Carbonates and evaporites show a depletion to the crustal average of Ge. There is a tendency for Ge to be slightly enriched in silicate minerals of late magmatic differentiates (e.g., muscovite granites), rocks that crystallize in the presence of a high volatile concentration (e.g., pegmatites, greisens) and late hydrothermal -
IMA–CNMNC Approved Mineral Symbols
Mineralogical Magazine (2021), 85, 291–320 doi:10.1180/mgm.2021.43 Article IMA–CNMNC approved mineral symbols Laurence N. Warr* Institute of Geography and Geology, University of Greifswald, 17487 Greifswald, Germany Abstract Several text symbol lists for common rock-forming minerals have been published over the last 40 years, but no internationally agreed standard has yet been established. This contribution presents the first International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) approved collection of 5744 mineral name abbreviations by combining four methods of nomenclature based on the Kretz symbol approach. The collection incorporates 991 previously defined abbreviations for mineral groups and species and presents a further 4753 new symbols that cover all currently listed IMA minerals. Adopting IMA– CNMNC approved symbols is considered a necessary step in standardising abbreviations by employing a system compatible with that used for symbolising the chemical elements. Keywords: nomenclature, mineral names, symbols, abbreviations, groups, species, elements, IMA, CNMNC (Received 28 November 2020; accepted 14 May 2021; Accepted Manuscript published online: 18 May 2021; Associate Editor: Anthony R Kampf) Introduction used collection proposed by Whitney and Evans (2010).

Box 9, FIN-00014 University of Helsinki, Finland Received May 28, 2001 Abstract—X-ray diffraction intensities from MnO and CoO were measured above and below their Néel tem- peratures and from NiO, below the Néel temperature. To detect possible characteristics of the paramagnetic and antiferromagnetic states of the crystals, the data were subjected to direct multipole analysis of the atomic- charge densities. For MnO, both spherical and nonspherical accumulation-of-charge densities indicate the exchange of the roles played by manganese and oxygen in the magnetic phase transition. Both spherical and nonspherical features characteristic of the ionic nature are inherent in both states. The electron counts of the density peaks correspond to Mn2+ and O1–, with the tenth electron of O2– being distributed in a wider region. In the paramagnetic state, there is an electronic Mn–Mn bond which seems to be formed due to coupling with the tenth electron of O2– and builds up a three-dimensional net of the charge density with the “cages” surround- ing oxygen atoms. -

To understand Ge incorporation mechanisms in natural systems, we investigate Ge speciation in Cu-bearing sulfide minerals using synchrotron X-ray fluorescence (XRF) chemical mapping and Ge K-edge µ-X-ray absorption near-edge structures (µ-XANES) spectroscopy. The samples investigated include (i) a homogeneous chalcopyrite from the Kipushi polymetallic deposit (Central African copperbelt, D.R. Congo) and (ii) a zoned Ge-rich chalcopyrite from the Barrigão Cu deposit (Iberian pyrite belt, Portugal). First, our spectroscopic analysis supports the occurrence of tetrahedrally-coordinated Ge4+ in chalcopyrite, independently from origins or zoning patterns observed for these minerals. Then, based on statistical analyses of XRF chemical maps, we demonstrate that tetravalent germanium most likely incorporates chalcopyrite through the Fe crystallographic site via coupled substitutions with the following form: (2x + 3y)Fe3+ $ (x + 2y)(Ge,Sn)4+ + x(Zn,Pb)2+ + y(Cu,Ag)+, although the presence of lattice vacancies cannot be completely excluded. -

Shallow Valence Band of Rutile Geo2 and P-Type Doping
Shallow Valence Band of Rutile GeO2 and P-type Doping Christian A. Niedermeier,1,* Keisuke Ide,1 Takayoshi Katase,1 Hideo Hosono,1,2 and Toshio Kamiya1,2 *Corresponding author: [email protected] 1Laboratory for Materials and Structures, Tokyo Institute of Technology, Yokohama 226-8503, Japan 2Materials Research Center for Element Strategy, Tokyo Institute of Technology, Yokohama 226-8503, Japan Abstract: GeO2 has an α-quartz-type crystal structure with a very wide fundamental band gap of 6.6 eV and is a good insulator. Here we find that the stable rutile-GeO2 polymorph with a 4.6 eV band gap has a surprisingly low ~6.8 eV ionization potential, as predicted from the band alignment using first-principles calculations. Because of the short O–O distances in the rutile structure containing cations of small effective ionic radii such as Ge4+, the antibonding interaction between O 2p orbitals raises the valence band maximum energy level to an extent that hole doping appears feasible. Experimentally, we report the flux growth of 1.5 × 1.0 × 0.8 mm3 large o rutile GeO2 single crystals and confirm the thermal stability for temperatures up to 1021 ± 10 C. X-ray fluorescence spectroscopy shows the inclusion of unintentional Mo impurities from the Li2O-MoO3 flux, as well as the solubility of Ga in the r-GeO2 lattice as a prospective acceptor dopant. The resistance of the Ga- and Mo-co-doped r-GeO2 single crystals is very high at room temperature, but it decreases by 2–3 orders of magnitude upon heating to 300 oC, which is attributed to thermally-activated p-type conduction. -
