    MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky.

  • Silver Sulphosalts in Galena from Espeland, Norway
    Silver sulphosalts in galena from Espeland, Norway M. S. NAIK Naik, M. S.: Silver sulphosalts in galena from Espeland, Norway. Norsk Geo­ logisk Tidsskrift, Vol. 55, pp. 185-189. Oslo 1975. The silver-bearing phases in galena from Espeland are freibergite, unknown 'phase C' (PbuA&l!Sbto�), pyrargyrite, stephanite and hessite. The composi­ tions of these phases were determined by electron microprobe. Freibergite is homogeneous in composition with an average 35 percent silver. The average calculated atomic proportions (Cu,Ag,Fe)t2.�b4S12·4• deviate from the stoi­ chiometric composition (Cu,Ag,Fe,Znh2(SbAs)4S13 of tetrahedrite. It has been found that most of the silver present in the ore occurs in the silver phases and not in structural positions in the galena lattice. M. S. Naik, Mineralogisk-geologisk museum, Sars gate l, Oslo 5, Norway. Present address: lndian School of Mines, Dhanbad, Bihar, India. Galenas with high contents of bismuth and silver have been described from Espeland and other localities in Norway by Oftedal (1942). He proposed that Bi atoms enter into the PbS lattice without causing any distortion, if an equal number of Ag atoms enter simultaneously. The excess of Bi over (BiAg) was considered to be responsible for the octahedral parting in some of these galenas. In the present study of the silver bearing galena from Espeland it has been found that the galena contains inclusions of several silver-bearing phases, as well as native bismuth, while the galena itself contains only nor­ mal amounts of Ag and essentially no Bi. Geology of the Espeland deposit The Espeland deposit is located SW of Vegårshei church, between the farms Myre and Espeland in Aust-Agder fylke, southern Norway.

  • Chapter 9 Gold-Rich Porphyry Deposits: Descriptive and Genetic Models and Their Role in Exploration and Discovery
    SEG Reviews Vol. 13, 2000, p. 315–345 Chapter 9 Gold-Rich Porphyry Deposits: Descriptive and Genetic Models and Their Role in Exploration and Discovery RICHARD H. SILLITOE 27 West Hill Park, Highgate Village, London N6 6ND, England Abstract Gold-rich porphyry deposits worldwide conform well to a generalized descriptive model. This model incorporates six main facies of hydrothermal alteration and mineralization, which are zoned upward and outward with respect to composite porphyry stocks of cylindrical form atop much larger parent plutons. This intrusive environment and its overlying advanced argillic lithocap span roughly 4 km vertically, an interval over which profound changes in the style and mineralogy of gold and associated copper miner- alization are observed. The model predicts a number of geologic attributes to be expected in association with superior gold-rich porphyry deposits. Most features of the descriptive model are adequately ex- plained by a genetic model that has developed progressively over the last century. This model is domi- nated by the consequences of the release and focused ascent of metalliferous fluid resulting from crys- tallization of the parent pluton. Within the porphyry system, gold- and copper-bearing brine and acidic volatiles interact in a complex manner with the stock, its wall rocks, and ambient meteoric and connate fluids. Although several processes involved in the evolution of gold-rich porphyry deposits remain to be fully clarified, the fundamental issues have been resolved to the satisfaction of most investigators. Explo- ration for gold-rich porphyry deposits worldwide involves geologic, geochemical, and geophysical work but generally employs the descriptive model in an unsophisticated manner and the genetic model hardly at all.

[email protected] Running title: Syntectonic mobility of supergene nickel ores Abstract Supergene nickel deposits of New Caledonia that have been formed in the Neogene by weathering of obducted ultramafic rocks are tightly controlled by fracture development. The relationship of tropical weathering and tectonic structures, faults and tension gashes, have been investigated in order to determine whether fractures have play a passive role only, as previously thought; or alternatively, if brittle tectonics was acting together with alteration.

  • STREAK Streak Means the Color of a Mineral in Its Powdered Form. The
    STREAK Streak means the color of a mineral in its powdered form. The name comes from the common method of observing it by scraping the mineral on a tile of white, unglazed porcelain to produce a narrow streak of powder. Streak is a valuable property because its color is usually the same even when larger samples of many minerals show a variety of colors. Streak is often better for mineral identification than color. Streak of metallic minerals Streak is valuable for identification of many metallic minerals, including native metals (such as gold), oxides and sulfide. Almost all of these minerals have metallic or submetallic luster and are opaque. Their streak is often quite different from their color in a hand sample, generally darker. Examples: Hematite: Hematite can occur as black crystals, steel gray in the form known as specularite, and as dull red earthy masses. Its streak, however, is always blood red. By this simple test hematite can be known apart from other black, metallic minerals of similar appearance. Pyrite: Pyrite comes in a brassy yellow color, but has a black or greenish-black streak. It is sometimes called “fool’s gold” because people mistook specks in ores for real gold. But native gold has a gold streak. Chalcopyrite and marcasite are closely related to pyrite. They have paler brassy colors than pyrite, but also show dark streaks. Bornite: Bornite is bronze color when fresh, but quickly tarnishes to blue and purple shades, and eventually turns black. Its streak, however, is always grayish black. Streak of nonmetallic minerals In contrast, most minerals with nonmetallic lusters are transparent or translucent, and have a streak paler than their color in hand-samples.

  • Theoretical Studies on As and Sb Sulfide Molecules
    Mineral Spectroscopy: A Tribute to Roger G. Bums © The Geochemical Society, Special Publication No.5, 1996 Editors: M. D. Dyar, C. McCammon and M. W. Schaefer Theoretical studies on As and Sb sulfide molecules J. A. TOSSELL Department of Chemistry and Biochemistry University of Maryland, College Park, MD 20742, U.S.A. Abstract-Dimorphite (As4S3) and realgar and pararealgar (As4S4) occur as crystalline solids con- taining As4S3 and As4S4 molecules, respectively. Crystalline As2S3 (orpiment) has a layered structure composed of rings of AsS3 triangles, rather than one composed of discrete As4S6 molecules. When orpiment dissolves in concentrated sulfidic solutions the species produced, as characterized by IR and EXAFS, are mononuclear, e.g. ASS3H21, but solubility studies suggest trimeric species in some concentration regimes. Of the antimony sulfides only Sb2S3 (stibnite) has been characterized and its crystal structure does not contain Sb4S6 molecular units. We have used molecular quantum mechanical techniques to calculate the structures, stabilities, vibrational spectra and other properties of As S , 4 3 As4S4, As4S6, As4SIO, Sb4S3, Sb4S4, Sb4S6 and Sb4SlO (as well as S8 and P4S3, for comparison with previous calculations). The calculated structures and vibrational spectra are in good agreement with experiment (after scaling the vibrational frequencies by the standard correction factor of 0.893 for polarized split valence Hartree-Fock self-consistent-field calculations). The calculated geometry of the As4S. isomer recently characterized in pararealgar crystals also agrees well with experiment and is calculated to be about 2.9 kcal/mole less stable than the As4S4 isomer found in realgar. The calculated heats of formation of the arsenic sulfide gas-phase molecules, compared to the elemental cluster molecules As., Sb, and S8, are smaller than the experimental heats of formation for the solid arsenic sulfides, but shown the same trend with oxidation state.

Thirty-six mineral species have been reported from the Rutherford mine alone,and the variety and perfection of many of thesehave led to their inclusion in most of the museums of the world. The concen- tration of unusual minerals in an easily accessible deposit at- tracted various scientific investigators and mineral collectors to this locality for successivegenerations.

Powder specimens of garnierite were annealed in static air between room temperature and 1000 ◦C. The kinetic of the transformation was investigated by means of thermo- gravimetric and differential thermal analysis, and the final product was extensively characterized via micro-Raman spectroscopy and X-ray diffraction. Our study shows that serpentine-like garnierite consists of a mixture of different mineral species. Furthermore, these garnierites and their compo- sition can provide details based on the mineralogy and the crystalline phases resulting from the thermal treatment.
