Gem Water cover:fa 17/5/09 23:06 Page 1 GEM WATER Adding crystals to water is both visually appealing and healthy. The water becomes infused with crystalline energy. It is a known fact that water carries mineral information and Gem Water provides effective remedies, acting quickly on a physical level. It is similar and complementary to wear- ing crystals, but the effects are not necessarily the same. The introduction to the book tells you all you need to know about the correct way to prepare Gem Water and pro- vides important information on which crystals to use and which not to prepare as Gem Water. The concept may appear simple at first, but you need to apply it with care, and the book explains all the facts you need to know before getting started. The second part of the book features more than 100 Michael Joachim Goebel Gienger, Crystals and 34 special mixtures with their effects as Gem Water remedies.

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. -

Frost ••• Inorganic Materials Research Program, Queensland University of Technology, 2 George Street, Brisbane, GPO Box 2434, Queensland 4001, Australia Abstract: Visible, near-infrared, IR and Raman spectra of magnesian gaspeite are presented along with explanations of spectral features. Of the cations, nickel ion is main source for the electronic features as a principal constituent in the mineral where as the bands in IR and Raman spectra are due to the vibrational processes in the carbonate ion as an entity. The combination of electronic absorption spectra and vibrational spectra (including near-infrared, FTIR and Raman) of magnesian gaspeite 2- are presented and explained the cation co-ordination and the behaviour of CO 3 anion in the Ni-Mg carbonate. The electronic absorption spectrum consists of three broad and intense bands at 8130, 13160 and 22730 cm-1 due to spin-allowed transitions and two weak bands at 20410 and 30300 cm -1 are assigned to spin- forbidden transitions of Ni 2+ in an octahedral symmetry. -

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. -
Systematics and Crystal Genesis of Carbonate Minerals
ГОДИШНИК НА МИННО-ГЕОЛОЖКИЯ УНИВЕРСИТЕТ “СВ. ИВАН РИЛСКИ”, Том 49, Св. I, Геология и геофизика, 2006 ANNUAL OF THE UNIVERSITY OF MINING AND GEOLOGY “ST. 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).
