The structure and spectral properties of two copper bearing 14 xocomecatlite and tlapallite are compared with an iron bearing rodalquilarite mineral. 15 Two prominent bands observed at 9855 and 9015 cm-1 are 16 2 2 2 2 2+ 17 assigned to B1g → B2g and B1g → A1g transitions of Cu ion in xocomecatlite. 18 19 The cause of spectral distortion is the result of many cations of Ca, Pb, Cu and Zn the 20 in tlapallite mineral structure. Rodalquilarite is characterised by ferric ion absorption 21 in the range 12300-8800 cm-1. 22 Three water vibrational overtones are observed in xocomecatlite at 7140, 7075 23 and 6935 cm-1 where as in tlapallite bands are shifted to low wavenumbers at 7135, 24 7080 and 6830 cm-1. The complexity of rodalquilarite spectrum increases with more 25 number of overlapping bands in the near-infrared. -

Early days were spent using LEGO robots to automate a rotating microscope stage thanks to the efforts of our colleague Peter Whalley (now deceased). This automation speeded up image capture and allowed us to take the thousands of photographs needed to make sizeable (Earth-based) virtual microscope collections. Virtual microscope methods are ideal for bringing rare and often unique samples to a wide audience so we were not surprised when 10 years ago we were approached by the UK Science and Technology Facilities Council who asked us to prepare a virtual collection of the 12 Moon rocks they loaned out to schools and universities. This would turn out to be one of many collections built using extra-terrestrial material. The major part of our extra-terrestrial work is web-based and we The authors - Mahesh Anand (left) and Andy Tindle (middle) with colleague have build collections of Europlanet meteorites, UK and Irish Peter Whalley (right). Thank you Peter for your pioneering contribution to the Virtual Microscope project. We could not have produced this book without your earlier efforts. 2 Moon Minerals is our latest output. We see it as a companion volume to Moon Rocks. Members of staff -

A Review of the Structural Architecture of Tellurium Oxycompounds

KAMPF 1 Research School of Earth Sciences and Department of Applied Mathematics, Research School of Physics and Engineering, Australian National University, Canberra, ACT 2601, Australia 2 Geosciences, Museum Victoria, GPO Box 666, Melbourne, Victoria 3001, Australia 3 Mineral Sciences Department, Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, CA 90007, USA [Received 24 November 2015; Accepted 23 February 2016; Associate Editor: Mark Welch] ABSTRACT Relative to its extremely low abundance in the Earth’s crust, tellurium is the most mineralogically diverse chemical element, with over 160 mineral species known that contain essential Te, many of them with unique crystal structures. We review the crystal structures of 703 tellurium oxysalts for which good refinements exist, including 55 that are known to occur as minerals. The dataset is restricted to compounds where oxygen is the only ligand that is strongly bound to Te, but most of the Periodic Table is represented in the compounds that are reviewed. The dataset contains 375 structures that contain only Te4+ cations and 302 with only Te6+, with 26 of the compounds containing Te in both valence states. Te6+ was almost exclusively in rather regular octahedral coordination by oxygen ligands, with only two instances each of 4- and 5-coordination. Conversely, the lone-pair cation Te4+ displayed irregular coordination, with a broad range of coordination numbers and bond distances. -
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. -
