Implications for Environmental and Economic Geology
UNIVERSITY OF CALIFORNIA RIVERSIDE Kinetics of the Dissolution of Scheelite in Groundwater: Implications for Environmental and Economic Geology A Thesis submitted in partial satisfaction of the requirements for the degree of Master of Science in Geological Sciences by Stephanie Danielle Montgomery March 2013 Thesis Committee: Dr. Michael A. McKibben, Chairperson Dr. Christopher Amrhein Dr. Timothy Lyons Copyright by Stephanie Danielle Montgomery 2013 The Thesis of Stephanie Danielle Montgomery is approved: _________________________________________ _________________________________________ _________________________________________ Committee Chairperson University of California, Riverside ABSTRACT OF THE THESIS Kinetics of the Dissolution of Scheelite in Groundwater: Implications for Environmental and Economic geology by Stephanie Danielle Montgomery Masters of Science, Graduate Program in Geological Sciences University of California, Riverside, March 2013 Dr. Michael McKibben, Chairperson Tungsten, an emerging contaminant, has no EPA standard for its permissible levels in drinking water. At sites in California, Nevada, and Arizona there may be a correlation between elevated levels of tungsten in drinking water and clusters of childhood acute lymphocytic leukemia (ALL). Developing a better understanding of how tungsten is released from rocks into surface and groundwater is therefore of growing environmental interest. Knowledge of tungstate ore mineral weathering processes, particularly the rates of dissolution of scheelite (CaWO4) in groundwater, could improve models of how tungsten is released and transported in natural waters. Our research focused on the experimental determination of the rates and products of scheelite dissolution in 0.01 M NaCl (a proxy for groundwater), as a function of temperature, pH, and mineral surface area. Batch reactor experiments were conducted within constant temperature circulation baths over a pH range of 3-10.5. -

GEOCHEMISTRY OF MINERALS, WATERS AND WEATHERING FROM THE FONTE SANTA MINE AREA (NE OF PORTUGAL) 1 2 3 1 4 M. E.P. Gomes , I.M.H.R. Antunes , A.M.R. Neiva , F.A.L. Pacheco , P.B. Silva 1Dep. of Geology, University of Trás-os-Montes e Alto Douro (UTAD), Portugal 2 Polytechnic Institute of Castelo Branco, Portugal 3 Department of Earth Sciences, University of Coimbra, Portugal 4 National Laboratory of Energy and Geology (LNEG, S. Mamede de Infesta), Portugal Abstract The quartz veins containing scheelite from Fonte Santa mine area were exploited for W between 1942 and 1982. At the end of November 2006, a flood event damaged the dam land of Fonte Santa mine and metal content of water increased. Fonte Santa mine area cuts the quartzites close to the Fonte Santa muscovite granite. The granite contains quartz, microcline, albite, muscovite, chlorite, columbite-tantalite, volframite, W-ixiolite and ilmenite. The quartz veins contain muscovite, chlorite, tourmaline, scheelite, pyrrhotite, pyrite, sphalerite, chalcopyrite, galena, arsenopyrite, magnetite, jarosite, phosphates of Pb, Fe and Al. The waters related to the Fonte Santa mine are poorly mineralized, with electrical conductivity < 965 µS / cm, of - 2- mixed type or HCO3 and SO4 types. These waters have Fe and Mn contents that forbid to use that for human consumption and agriculture. Sodium, Mg and K water contents are associated with the alteration of albite, chlorite and muscovite of country rock, while Ca is related to the W-bearing quartz veins. Key-words: mineralizations, scheelite, waters, contamination Resumo Os filões de quartzo contendo scheelite da mina de Fonte Santa foram explorados para W entre 1942 e 1982. -

Oxygenic Bismuth Minerals in the NE Part of the Karkonosze Pluton (West Sudetes, SW Poland)
Acta Geologica Polonica, Vol. 68 (2018), No. 4, pp. 537–554 DOI: 10.1515/agp-2018-0016 Oxygenic bismuth minerals in the NE part of the Karkonosze pluton (West Sudetes, SW Poland) ANDRZEJ KOZŁOWSKI and WITOLD MATYSZCZAK* Faculty of Geology, University of Warsaw, Żwirki i Wigury 93, PL-02-089 Warszawa, Poland. *E-mail: [email protected] ABSTRACT: Kozłowski, A. and Matyszczak, W. 2018. Oxygenic bismuth minerals in the NE part of the Karkonosze pluton (West Sudetes, SW Poland). Acta Geologica Polonica, 68 (4), 537–554. Warszawa. The study presents fifteen oxygen-bearing secondary minerals of bismuth from the north-eastern part of the Variscan Karkonosze granitoid pluton in the northern zone of the Bohemian massif. The minerals were inves- tigated by optical, electron microprobe, classic chemical, XRD, IR absorption and fluid inclusion methods. The late, very low temperature epithermal solutions most probably caused formation of sillénite, kusachiite, bismoclite, bismutite, beyerite, kettnerite, pucherite, schumacherite, namibite and eulytite. Solutions dominated by supergene (meteoric) waters were the parents for bismite, russellite, koechlinite, ximengite and walpurgite. The paper also contains information on early research on the investigated minerals. Key words: Karkonosze granitoid pluton; Bismuth minerals; Secondary minerals; Oxidation; Vein; Pegmatite. FOREWORD joined by WM as the co-author, interested like him in further investigations of the Karkonosze pluton (see The paper presents an investigation of several ox- e.g., Matyszczak 2018). ygen-bearing minerals of bismuth, which were found in the Karkonosze granitoid, collected during field work by AK in 1976–1990.

McDONALD§ Department of Earth Sciences, Laurentian University, Sudbury Ontario P3E 2C6, Canada ¶ GEORGE Y. CHAO Ottawa–Carleton Geoscience Centre, Department of Earth Sciences, Carleton University, Ottawa Ontario K1S 5B6, Canada ABSTRACT Bobtraillite is a new, complex zirconosilicate found in igneous breccias and nepheline syenite pegmatites at the Poudrette quarry, Mont Saint-Hilaire, Quebec. It is associated with a burbankite-group mineral, donnayite-(Y), clinoamphibole, albite, aegirine, pyrrhotite, pyrite, annite, analcime, microcline, a white mica (muscovite?), yellow titanite, clinopyroxene and calcite. Crystals are commonly grey to brown in color, blocky to prismatic, elongate along [001], with a maximum length of 2 mm. It is generally found as isolated single crystals or simple parallel intergrowths with two or three members, rarely in small (<0.1 mm) rosettes. It is transparent with a vitreous luster and a white streak, and is non-luminescent. The Mohs hardness is 5½; no cleavage is evident. It is brittle and has an uneven to conchoidal fracture. The calculated density is 3.16 g/cm3. Bobtraillite is nonpleochroic, uniaxial positive, with 1.627(1) and 1.645(1). Seven analyses made on one crystal gave: Na2O 5.62, CaO 1.11, SrO 17.76, BaO 0.40, B2O3 (calc.) 3.38, Y2O3 1.15, SiO2 40.51, ZrO2 25.32, HfO2 0.48, Nb2O5 1.32 and H2O (calc.) 5.25, total 102.30 wt.%, corresponding to (Na11.20Ca1.22)⌺12.42(Sr10.59Ba0.16)⌺10.75 (Zr12.69Y0.63Nb0.61Hf0.14)⌺14.07 Si41.64B6O132(OH)12•12H2O on the basis of 156 anions, or ideally, (Na,Ca)13Sr11(Zr,Y,Nb)14Si42B6O132(OH)12•12H2O. -

In this work, total energy calculations were performed in order to analyze the structural behavior of the experimentally known polymorphs of InVO4: α-MnMoO4- type (I), CrVO4-type (III), and the wolframite (V). Besides, in this paper we present our results about the stability of this compound beyond the pressures reached by experiments. We propose some new high pressure phases based in the study of 13 possible candidates. The quasiharmonic approximation has been used to calculate the sequence of phase transitions at 300 K: CrVO4-type, III (in parentheses the transition pressure) ! wolframite, V (4.4 GPa) ! raspite, VI (28.1 GPa) ! AgMnO4-type, VII (44 GPa). Equations of state and phonon frequencies as function of pressure have been calculated for the studied phases. In order to determine the stability of each phase we also report the phonon dispersion along the Brillouin zone and the phonon density of states for the most stable polymorphs. -
