The Minerals and Rocks of the Earth 5A: the Minerals- Special Mineralogy
Lesson 5 cont’d: The Minerals and Rocks of the Earth 5a: The minerals- special mineralogy A. M. C. Şengör In the previous lectures concerning the materials of the earth, we studied the most important silicates. We did so, because they make up more than 80% of our planet. We said, if we know them, we know much about our planet. However, on the surface or near-surface areas of the earth 75% is covered by sedimentary rocks, almost 1/3 of which are not silicates. These are the carbonate rocks such as limestones, dolomites (Americans call them dolostones, which is inappropriate, because dolomite is the name of a person {Dolomieu}, after which the mineral dolomite, the rock dolomite and the Dolomite Mountains in Italy have been named; it is like calling the Dolomite Mountains Dolo Mountains!). Another important category of rocks, including parts of the carbonates, are the evaporites including halides and sulfates. So we need to look at the minerals forming these rocks too. Some of the iron oxides are important, because they are magnetic and impart magnetic properties on rocks. Some hydroxides are important weathering products. This final part of Lesson 5 will be devoted to a description of the most important of the carbonate, sulfate, halide and the iron oxide minerals, although they play a very little rôle in the total earth volume. Despite that, they play a critical rôle on the surface of the earth and some of them are also major climate controllers. The carbonate minerals are those containing the carbonate ion -2 CO3 The are divided into the following classes: 1. -

ABSTRACT Minerals containing cobalt as an essential element display systematic trends in their diversity and distribution. We employ data for 66 approved Co mineral species (as tabulated by the official mineral list of the International Mineralogical Association, http://rruff.info/ima, as of 1 March 2016), represent- ing 3554 mineral species-locality pairs (www.mindat.org and other sources, as of 1 March 2016). We find that cobalt-containing mineral species, for which 20% are known at only one locality and more than half are known from five or fewer localities, conform to a Large Number of Rare Events (LNRE) distribution. Our model predicts that at least 81 Co minerals exist in Earth’s crust today, indicating that at least 15 species have yet to be discovered—a minimum estimate because it assumes that new minerals will be found only using the same methods as in the past. Numerous additional cobalt miner- als likely await discovery using micro-analytical methods. -
The Origins of Color in Minerals Four Distinct Physical Theories
American Mineralogist, Volume 63. pages 219-229, 1978 The origins of color in minerals KURT NASSAU Bell Laboratories Murray Hill, New Jersey 07974 Abstract Four formalisms are outlined. Crystal field theory explains the color as well as the fluores- cence in transition-metal-containing minerals such as azurite and ruby. The trap concept, as part of crystal field theory, explains the varying stability of electron and hole color centers with respect to light or heat bleaching, as well as phenomena such as thermoluminescence. The molecular orbital formalism explains the color of charge transfer minerals such as blue sapphire and crocoite involving metals, as well as the nonmetal-involving colors in lazurite, graphite and organically colored minerals. Band theory explains the colors of metallic minerals; the color range black-red-orange- yellow-colorless in minerals such as galena, proustite, greenockite, diamond, as well as the impurity-caused yellow and blue colors in diamond. Lastly, there are the well-known pseudo- chromatic colors explained by physical optics involving dispersion, scattering, interference, and diffraction.

Email: [email protected] 9 (Submitted on 24 March, 201; revised version on 30 June 2014) 10 11 Abstract– The incorporation of cobalt in mixed metal carbonates is a possible route to the immobilization 12 of this toxic element in the environment. However, the thermodynamics of (Ca,Co)CO3 solid solutions are 13 still unclear due to conflicting data from experiment and from the observation of natural ocurrences. We 14 report here the results of a computer simulation study of the mixing of calcite (CaCO3) and spherocobaltite 15 (CoCO3), using density functional theory calculations. Our simulations suggest that previously proposed 16 thermodynamic models, based only on observed compositions, significantly overestimate the solubility 17 between the two solids and therefore underestimate the extension of the miscibility gap under ambient 18 conditions. The enthalpy of mixing of the disordered solid solution is strongly positive and moderately 19 asymmetric: calcium incorporation in spherocobaltite is more endothermic than cobalt incorporation in 20 calcite. -

THE CHARACTERIZATION OF ARSENIC MINERAL PHASES FROM LEGACY MINE WASTE AND SOIL NEAR COBALT, ONTARIO by Jeff Clarke A research project submitted to the Department of Geological Sciences and Geological Engineering In conformity with the requirements for the degree of Master of Science in Applied Geology Queen’s University Kingston, Ontario, Canada (July, 2017) Copyright © Jeff Clarke, 2017 i ABSTRACT The Cobalt-Coleman silver (Ag) mining camp has a long history of mining dating back to 1903. Silver mineralization is hosted within carbonate veins and occurs in association with Fe-Co-Ni arsenide and sulpharsenide mineral species. The complex mineralogy presented challenges to early mineral processing methods with varying success of Ag recovery and a significant amount of arsenic (As) in waste material which was disposed in the numerous tailings deposits scattered throughout the mining camp, and in many instances disposed of uncontained. The oxidation and dissolution of As-bearing mineral phases in these tailings and legacy waste sites releases As into the local aquatic environment. Determining the distribution of primary and secondary As mineral species in different legacy mine waste materials provides an understanding of the stability of As. Few studies have included detailed advanced mineralogical characterization of As mineral species from legacy mine waste in the Cobalt area. As part of this study, a total of 28 samples were collected from tailings, processed material near mill sites and soils from the legacy Nipissing and Cart Lake mining sites. The samples were analyzed for bulk chemistry to delineate material with strongly elevated As returned from all sample sites. This sampling returned highly elevated As with up to 6.01% As from samples near mill sites, 1.71% As from tailings and 0.10% As from soils. -

MANDARINO Department of Earth Sciences, Royal Ontario Museum, 100 Queen’s Park, Toronto, Ontario M5S 2C6, Canada ABSTRACT A suite of nickel minerals, gaspéite, retgersite and nickelhexahydrite, was found in veins of altered ultramafic rocks from Duboˇstica, Bosnia and Hercegovina, in material deposited in the National Museum in Sarajevo. Unit-cell dimensions and vol- umes of the minerals are: gaspéite: a 4.648(3), c 14.95(2) Å (rhombohedral cell a 5.660 Å, ␣ 48.49°), V 279.7 Å3; retgersite: a 6.787(5), c 18.27(2) Å, V 842(1) Å3; nickelhexahydrite: a 9.925(7), b 7.232(7), c 24.16(2),  98.55(7)°, V 1715(2) Å3. The chemical composition of the gaspéite from Duboˇstica, obtained by ICP–AES analysis, is: NiO 49.63, MgO 0.17, CaO 0.45, FeO 6.36, CO2 43.25, total 99.87 wt%. This gives the empirical formula (based on three atoms of oxygen) (Ni0.73Fe0.10Ca0.01)⌺0.84 C1.08O3.00. The association of gaspéite, retgersite and nickelhexahydrite has formed as a result of reactions involving a series of kinetically controlled transitory equilibria, and is characteristic of near-surface hydrothermal alteration. -

Infrared absorption and Raman spectra were compared with the known experimental data of synthetic and natural crystals. For lattice and intramolecular modes, linear dependences on the radius and mass of the metal cation are established. The obtained dependences have predictive power and can be used to study solid carbonate solutions. For trigonal and orthorhombic carbonates, the linear dependence of wavenumbers on the cation radius RM (or M–O distance) is established for the infrared in-plane bending mode: 786.2–65.88 R and Raman in-plane stretching mode: 768.5–53.24 R , with a · M · M correlation coefficient of 0.87. -
