([email protected]) Introduction: Terrestrial analogue studies have part of the basin (Kunteyi depression). The Pliocene is served much critical information for understanding the first major salt forming period for Qaidam Basin, Mars [1]. Playa sediments in Qaidam Basin have a and the salt bearing sediments formed at the southwest complete set of salt minerals, i.e. carbonates, sulfates, part are dominated by sulfates, and those formed at the and chlorides,which have been identified on Mars northwest part of basin are partially sulfates dominate [e.g. 2-4]. The geographical conditions and high eleva- and partially chlorides dominate. After Pliocene, the tion of these playas induces Mars-like environmental deposition center started to move towards southeast conditions, such as low precipitation, low relative hu- until reaching the east part of the basin at Pleistocene, midity, low temperature, large seasonal and diurnal T reaching the second major salt forming stage, and the variation, high UV radiation, etc. [5,6]. Thus the salt bearing sediments formed at this stage are mainly playas in the Qaidam Basin servers a good terrestrial chlorides dominate. The distinct change in salt mineral reference for studying the depositional and secondary assemblages among deposition centers indicates the processes of martian salts. migration and geochemical differentiation of brines From 2008, a set of analogue studies have been inside the basin. -

I`mt`qx1//4Lhmdq`knesgdLnmsg9Fk`tadqhsd Glauberite is something of a paradox among minerals, better known for specimens in which it is not present, than for those in which it is. In other words, glauberite is one of the Mineral Kingdom’s most widely pseudomorphed species, as the write-up will explain. We’ll also talk about the former Mineral of the Month Club. OGXRHB@K OQNODQSHDR Chemistry: Na2Ca(SO4)2 Sodium Calcium Sulfate Class: Sulfates Sub-Group: Anhydrous Sulfates Group: Glauberite Crystal System: Monoclinic Crystal Habits: Tabular or prismatic; steeply inclined, wedge-to-tabular-shaped dipyramidal crystals, sometimes with rounded edges; striated on several faces; pseudomorphic replacement common; also forms epimorphic Figure 1. Glauberite crystal. crystals, in which a second mineral encrusts the original glauberite crystals which then dissolve away to leave hollow, outer shells. Color: Colorless in unaltered crystals; altered or partially altered crystals yellowish or grayish, often white due to a powdery, efflorescent coating that forms upon prolonged exposure to dry air. Luster: Vitreous when free of efflorescent coating Transparency: Transparent to translucent; unaltered crystals usually transparent Streak: White Refractive Index: 1.51-1.53 Cleavage: Perfect in one direction Fracture: Very brittle, producing small conchoidal fragments Hardness: 2.5-3.0 Specific Gravity: 2.7-2.8 Luminescence: None Distinctive Features and Tests: Occurrence in evaporate deposits and association with such minerals as halite (sodium chloride, NaCl), calcite (calcium carbonate, CaCO3), thenardite (sodium sulfate, Na2SO4), gypsum (hydrous calcium sulfate, CaSO4AH2O). Sometimes confused with halite and calcite, but glauberite lacks halite’s pronounced cubic shape and dissolves more slowly in water. -

Carbon Mineral Ecology: Predicting the Undiscovered Minerals of Carbon
American Mineralogist, Volume 101, pages 889–906, 2016 Carbon mineral ecology: Predicting the undiscovered minerals of carbon ROBERT M. HAZEN1,*, DANIEL R. HUMMER1, GRETHE HYSTAD2, ROBERT T. DOWNS3, AND JOSHUA J. GOLDEN3 1Geophysical Laboratory, Carnegie Institution, 5251 Broad Branch Road NW, Washington, D.C. 20015, U.S.A. 2Department of Mathematics, Computer Science, and Statistics, Purdue University Calumet, Hammond, Indiana 46323, U.S.A. 3Department of Geosciences, University of Arizona, 1040 East 4th Street, Tucson, Arizona 85721-0077, U.S.A. ABSTRACT Studies in mineral ecology exploit mineralogical databases to document diversity-distribution rela- tionships of minerals—relationships that are integral to characterizing “Earth-like” planets. As carbon is the most crucial element to life on Earth, as well as one of the defining constituents of a planet’s near-surface mineralogy, we focus here on the diversity and distribution of carbon-bearing minerals. We applied a Large Number of Rare Events (LNRE) model to the 403 known minerals of carbon, using 82 922 mineral species/locality data tabulated in http://mindat.org (as of 1 January 2015). We find that all carbon-bearing minerals, as well as subsets containing C with O, H, Ca, or Na, conform to LNRE distributions. Our model predicts that at least 548 C minerals exist on Earth today, indicating that at least 145 carbon-bearing mineral species have yet to be discovered. Furthermore, by analyzing subsets of the most common additional elements in carbon-bearing minerals (i.e., 378 C + O species; 282 C + H species; 133 C + Ca species; and 100 C + Na species), we predict that approximately 129 of these missing carbon minerals contain oxygen, 118 contain hydrogen, 52 contain calcium, and more than 60 contain sodium. -
STRONG and WEAK INTERLAYER INTERACTIONS of TWO-DIMENSIONAL MATERIALS and THEIR ASSEMBLIES Tyler William Farnsworth a Dissertati
STRONG AND WEAK INTERLAYER INTERACTIONS OF TWO-DIMENSIONAL MATERIALS AND THEIR ASSEMBLIES Tyler William Farnsworth A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Chemistry. Chapel Hill 2018 Approved by: Scott C. Warren James F. Cahoon Wei You Joanna M. Atkin Matthew K. Brennaman © 2018 Tyler William Farnsworth ALL RIGHTS RESERVED ii ABSTRACT Tyler William Farnsworth: Strong and weak interlayer interactions of two-dimensional materials and their assemblies (Under the direction of Scott C. Warren) The ability to control the properties of a macroscopic material through systematic modification of its component parts is a central theme in materials science. This concept is exemplified by the assembly of quantum dots into 3D solids, but the application of similar design principles to other quantum-confined systems, namely 2D materials, remains largely unexplored. Here I demonstrate that solution-processed 2D semiconductors retain their quantum-confined properties even when assembled into electrically conductive, thick films. Structural investigations show how this behavior is caused by turbostratic disorder and interlayer adsorbates, which weaken interlayer interactions and allow access to a quantum- confined but electronically coupled state. I generalize these findings to use a variety of 2D building blocks to create electrically conductive 3D solids with virtually any band gap. I next introduce a strategy for discovering new 2D materials. Previous efforts to identify novel 2D materials were limited to van der Waals layered materials, but I demonstrate that layered crystals with strong interlayer interactions can be exfoliated into few-layer or monolayer materials. -

Systematics and Crystal Genesis of Carbonate Minerals

IVAN RILSKI”, Vol. 49, Part I, Geology and GeopHysics, 2006 SYSTEMATICS AND CRYSTAL GENESIS OF CARBONATE MINERALS Ivan Kostov, Ruslan I. Kostov University of Mining and Geology “St. Ivan Rilski”, Sofia 1700; [email protected] ABSTRACT. A dual crystal structural and paragenetic principle (Kostov, 1993; Kostov, Kostov, 1999) Has been applied to a rational classification of tHe carbonate minerals. Main divisions (associations) are based on geocHemically allied metals in tHe composition of tHese minerals, and subdivisions (axial, planar, pseudoisometric and isometric types) on tHeir overall structural anisometricity. The latter provides botH structural similarity and genetic information, as manner of crystal groWtH in geological setting under different conditions of crystallization. The structural anisometricity may conveniently be presented by tHe c/a ratio of tHe minerals WitH HigH symmetry and by tHe 2c/(a+b), 2b/(a+c) and 2a/(b+c) ratios for tHe loW symmetry minerals. The respective ratios are less, nearly equal, equal or above 1.00. The unit cell or sub-cell and tHe corresponding structures are denoted as axial or A-type, pseudo-isometric or (I)-type, isometric or I-type and planar or P- type, notations WHicH correspond to cHain-like, frameWork and sHeet-like structures, respectively ino-, tecto- and pHyllo-structures. The classification includes tHree geocHemical assemblages among tHe carbonate minerals – Al-Mg-Fe(Ni,Co,Mn), Na-Ca-Ba(К)-REE and Zn-Cu-Pb(U).

GEOLOGICAL ASSOCIATION OF CANADA MINERALOGICAL ASSOCIATION OF CANADA 2006 JOINT ANNUAL MEETING MONTRÉAL, QUÉBEC FIELD TRIP 4A : GUIDEBOOK MINERALOGY AND GEOLOGY OF THE POUDRETTE QUARRY, MONT SAINT-HILAIRE, QUÉBEC by Charles Normand (1) Peter Tarassoff (2) 1. Département des Sciences de la Terre et de l’Atmosphère, Université du Québec À Montréal, 201, avenue du Président-Kennedy, Montréal, Québec H3C 3P8 2. Redpath Museum, McGill University, 859 Sherbrooke Street West, Montréal, Québec H3A 2K6 1 INTRODUCTION The Poudrette quarry located in the East Hill suite of the Mont Saint-Hilaire alkaline complex is one of the world’s most prolific mineral localities, with a species list exceeding 365. No other locality in Canada, and very few in the world have produced as many species. With a current total of 50 type minerals, the quarry has also produced more new species than any other locality in Canada, and accounts for about 25 per cent of all new species discovered in Canada (Horváth 2003). Why has a single a single quarry with a surface area of only 13.5 hectares produced such a mineral diversity? The answer lies in its geology and its multiplicity of mineral environments. INTRODUCTION La carrière Poudrette, localisée dans la suite East Hill du complexe alcalin du Mont Saint-Hilaire, est l’une des localités minéralogiques les plus prolifiques au monde avec plus de 365 espèces identifiées. Nul autre site au Canada, et très peu ailleurs au monde, n’ont livré autant de minéraux différents. Son total de 50 minéraux type à ce jour place non seulement cette carrière au premier rang des sites canadiens pour la découverte de nouvelles espèces, mais représente environ 25% de toutes les nouvelles espèces découvertes au Canada (Horváth 2003).
