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.

Rock Thermochemistry Laboratory and NEAT ORU, University of California Davis, One Shields Avenue, Davis, California 95616, United States *S Supporting Information ABSTRACT: We demonstrate the use of ball milling mechanochemistry for rapid, simple, and materials-efficient · synthesis of the organic mineral paceite CaCu(OAc)4 6H2O (where OAc− is the acetate ion), composed of coordination polymer chains containing alternating Ca2+ and Cu2+ ions, as · well as its cadmium-based analogue CaCd(OAc)4 6H2O. While the synthesis of paceite in aqueous solutions requires a high excess of the copper precursor, mechanochemistry permits the use of stoichiometric amounts of reagents, as well as the use of poorly soluble and readily accessible calcium carbonate or hydroxide reactants. As established by thermochemical measurements, enthalpies of formation of both synthetic paceite and its cadmium analogue relevant to the mechanochemical reactions are highly exothermic. Reactions can also be conducted using accelerated aging, a synthetic technique that mimics geological processes of mineral weathering. Accelerated aging reactivity involving copper(II) acetate monohydrate (hoganite) and calcium carbonate (calcite) provides a potential explanation of how complex organic minerals like paceite could form in a geological environment.

  • A Review of the Structural Architecture of Tellurium Oxycompounds
    Mineralogical Magazine, May 2016, Vol. 80(3), pp. 415–545 REVIEW OPEN ACCESS A review of the structural architecture of tellurium oxycompounds 1 2,* 3 A. G. CHRISTY ,S.J.MILLS AND A. R. 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.

  • Cesbronite, a New Copper Tellurite from Moctezuma, Sonora
    MINERALOGICAL MAGAZINE, SEPTEMBER 1974, VOL. 39, PP. 744-6 Cesbronite, a new copper tellurite from Moctezuma, Sonora SIDNEY A. WILLIAMS Phelps Dodge Corporation, Douglas, Arizona SUMMARY. Cesbronite occurs at the Bambollita mine, near Moctezuma, Sonora, with a variety of other tellurites. The colour is 'green beetle' (R.H.S. 135-B) with a pale streak. H 3; Dmeas 4"45:1:0'2. Crystals are orthorhombic 2 mmm with a 8'624 A, b I I '878, C5'872 (all :I:0'016 A); space group Pbcn. For Z = 2 the calculated density is 4'455 gfcm3. The strongest powder lines are 5'934 (100),3'490 (92), 4'889 (71), 2'358 (70), 2'379 (38),1'592 (34), 2'156 (28), and 1.698 (27). Electron-probe analysis gave: CuO 50'3 %, 50'3, 49'8, 49'4; TeO. 39'3 %. 39'2, 38,6, 38,6. Water determined gravimetrically II'O"la. This gives CU5(Te03).(OH)6.2H.O. Cesbronite is pleochroic with absorption y ~ f3 ?> a:. Optically positive with 2Vy calc. 72°; a: 1.880 11[100],f3 1'928 I![OOI],y 2'02911[010]. CESBRONITE was first collected by Peter Embrey and Pierre Bariand during a visit we made to the Bambollita (La Oriental) mine near Moctezuma, Sonora. The mineral is named in honour of Dr. Fabien Cesbron, French mineralogist. There are two thin veins exposed in this mine, and cesbronite occurs in only one. This vein is closer to the portal and is more severely oxidized than the other vein (where quetzalcoatlite occurs).

Raman 14 spectroscopy has been used to study the tellurite minerals teineite and 15 graemite; both contain water as an essential element of their stability. 16 The tellurite ion should show a maximum of six bands. The free 17 tellurite ion will have C3v symmetry and four modes, 2A1 and 2E. 18 Raman bands for teineite at 739 and 778 cm-1 and for graemite at 768 -1 2- 19 and 793 cm are assigned to the ν1 (TeO3) symmetric stretching mode 20 whilst bands at 667 and 701 cm-1 for teineite and 676 and 708 cm-1 for 2- 21 graemite are attributed to the the ν3 (TeO3) antisymmetric stretching 22 mode. The intense Raman band at 509 cm-1 for both teineite and 23 graemite is assigned to the water librational mode.

  • By Michael Fleischer and Constance M. Schafer Open-File Report 81
    U.S. DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY THE FORD-FLEISCHER FILE OF MINERALOGICAL REFERENCES, 1978-1980 INCLUSIVE by Michael Fleischer and Constance M. Schafer Open-File Report 81-1174 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards 1981 The Ford-Fleischer File of Mineralogical References 1978-1980 Inclusive by Michael Fleischer and Constance M. Schafer In 1916, Prof. W.E. Ford of Yale University, having just published the third Appendix to Dana's System of Mineralogy, 6th Edition, began to plan for the 7th Edition. He decided to create a file, with a separate folder for each mineral (or for each mineral group) into which he would place a citation to any paper that seemed to contain data that should be considered in the revision of the 6th Edition. He maintained the file in duplicate, with one copy going to Harvard University, when it was agreed in the early 1930's that Palache, Berman, and Fronde! there would have the main burden of the revision. A number of assistants were hired for the project, including C.W. Wolfe and M.A. Peacock to gather crystallographic data at Harvard, and Michael Fleischer to collect and evaluate chemical data at Yale. After Prof. Ford's death in March 1939, the second set of his files came to the U.S. Geological Survey and the literature has been covered since then by Michael Fleischer. Copies are now at the U.S. Geological Survey at Reston, Va., Denver, Colo., and Menlo Park, Cal., and at the U.S.

It occurs in vugs in quartz in association with Br-rich chlorargyrite, gold, 21 housleyite, khinite, markcooperite, and ottoite. It is interpreted as having formed from the partial 22 oxidation of primary sulfides and tellurides during or following brecciation of quartz veins. 23 Eckhardite is monoclinic, space group P21/n, with unit cell dimensions a = 8.1606(8), b = 24 5.3076(6), c = 11.4412(15) Å, β = 101.549(7)°, V = 485.52(10) Å3, and Z = 4. It forms as needles 25 or blades up to about 150 x 15 x 5 µm in size, typically in radial or sub-radial aggregates, but also 26 as isolated needles.

The results of high-temperature PXRD experiments revealed that the structure of uricite is stable up to 380 ◦C, and then it loses crystallinity. The crystal structure of tinnunculite is relatively stable up to 40 ◦C, whereas above this temperature, rapid release of H2O molecules occurs followed by the direct transition to uricite phase without intermediate hydration states. SCXRD studies and IR spectroscopy data confirmed the similarity of uricite and tinnunculite crystal structures.
