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. -
Empressite, Agte, from the Empress-Josephine Mine, Colorado, U.S.A.: Composition, Physical Properties, and Determination of the Crystal Structure
American Mineralogist, Volume 89, pages 1043–1047, 2004 Empressite, AgTe, from the Empress-Josephine mine, Colorado, U.S.A.: Composition, physical properties, and determination of the crystal structure LUCA BINDI,1,* PAUL G. SPRY,2 AND CURZIO CIPRIANI1 1 Museo di Storia Naturale, Sezione di Mineralogia, Università degli Studi di Firenze, Via La Pira, 4 I-50121 Firenze, Italy 2 Department of Geological and Atmospheric Sciences, 253 Science I, Iowa State University, Ames, Iowa 50011-3210, U.S.A. ABSTRACT The chemistry and composition of empressite, AgTe, a rare silver telluride mineral, has been mistaken in the mineralogical literature for the silver telluride stützite (Ag5–xTe3). Empressite from the type locality, the Empress-Josephine deposit (Colorado), occurs as euhedral prismatic grains up to 400 μm in length and contains no inclusions or intergrowths with other minerals. It is pale bronze in color and shows a grey-black to black streak. No cleavage is observed in empressite but it shows an uneven to subconchoidal 2 fracture and Vickers hardness (VHN25) of 142 kg/mm . Empressite is greyish white in color, with strong bireflectance and pleochroism. Reflectance percentages forR min and Rmax are 40.1, 45.8 (471.1 nm), 39.6, 44.1 (548.3 nm), 39.4, 43.2 (586.6 nm), and 38.9, 41.8 (652.3 nm), respectively. Empressite is orthorhombic and belongs to space group Pmnb (Pnma as standard), with the fol- lowing unit-cell parameters: a = 8.882(1), b = 20.100(5), c = 4.614(1) Å, V = 823.7(3) Å3, and Z = 16. -

Modern mineralogy of gold: overview and new data Minéralogie moderne de l’or : bilan et nouvelles données Ernst Spiridonov* and Denka Yanakieva** Abstract: We suppose that it should be useful for archaeologists to have an overview on gold mineralogy, because 1) in ancient times, part of the golden objects were made directly from natural golden nuggets; 2) most of the Au in ores exists as its own minerals. he major part of the Au in the planets and meteorites of our Solar system is found in high temperature solid solutions: metallic Fe-Ni and monosulides Fe-Ni and Fe-Cu. Au leaves them under luid or some other reworking. As a result, Au minerals are formed. hey are mainly developed in hydrothermal deposits of the upper part of Earth’s continental crust. -

Bauer, 1971, pp. 231-234 in: San Luis Basin (Colorado), James, H. L.; [ed.], New Mexico Geological Society 22nd Annual Fall Field Conference Guidebook, 340 p. This is one of many related papers that were included in the 1971 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

The specimen was discovered in a fragment from the cameronite [ideally, Cu5-x(Cu,Ag)3+xTe10] holotype material from the Good Hope mine, Vulcan, Colorado (U.S.A.). It occurs as black grains of subhedral to anhedral morphology, with a maximum size up to 65 µm, and shows black streaks. No cleavage is −2 observed and the Vickers hardness (VHN100) is 158 kg·mm . Reflectance percentages in air for Rmin and Rmax are 38.1, 38.9 (471.1 nm), 36.5, 37.3 (548.3 nm), 35.8, 36.5 (586.6 nm), 34.7, 35.4 (652.3 nm). Spiridonovite has formula (Cu1.24Ag0.75)S1.99Te1.01, ideally (Cu1-xAgx)2Te (x ≈ 0.4). The mineral is trigonal and belongs to the space group P-3c1, with the following unit-cell parameters: a = 4.630(2) Å, c = 22.551(9) Å, V = 418.7(4) Å 3, and Z = 6. -
