    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.

    The Geochemistry and Mobility of Zinc in the Regolith. Advances in Regolith 2003 289

    Advances in Regolith 2003 287 THE GEOCHEMISTRY AND MOBILITY OF ZINC IN THE REGOLITH D. C. McPhail1, Edward Summerhayes1, Susan Welch1 & Joël Brugger2 CRC LEME, Department of Geology, Australian National University, Canberra, ACT, 0200 1South Australian Museum and Adelaide University, Adelaide, SA 5000 INTRODUCTION The mobility of zinc in the regolith is important for several reasons, including the weathering of zinc deposits, formation of non-sulphide zinc deposits and contamination of soils and waters from human impact. The mobility of zinc is also important more generally to geologists and geochemists, both exploration and otherwise, because of the need to understand the formation of zinc ore deposits, such as Mississippi Valley Type (MVT), volcanic-hosted massive sulphide (VHMS), zinc oxide and others in which zinc occurs. This means that exploration geochemists, economic geologists and environmental scientists need to understand how zinc exists in the regolith, different lithologies and water, how it is mobilized or trapped, how far it can be transported and whether it is bioavailable and acts as either a micronutrient or a toxin to plant and animal life. In economic geology, there is presently an increasing interest in the formation of zinc oxide, or non- sulphide zinc deposits, and this is reflected in a recent special issue in the journal Economic Geology (Sangster 2003). Although the mobility of zinc in the regolith depends on the transporting process (e.g., groundwater advection or convection, sediment or airborne physical transport, biotic), it depends substantially on the geochemistry of zinc, i.e., how does zinc exist in groundwater and the regolith materials and what are the important geochemical reactions between water and solid.

    THE PYROPHANITE–ECANDREWSITE SOLID-SOLUTION: CRYSTAL STRUCTURES of the Mn1–Xznxtio3 SERIES (0.1 ≤ X ≤ 0.8)

    1871 The Canadian Mineralogist Vol. 42, pp. 1871-1880 (2004) THE PYROPHANITE–ECANDREWSITE SOLID-SOLUTION: CRYSTAL STRUCTURES OF THE Mn1–xZnxTiO3 SERIES (0.1 ≤ x ≤ 0.8) ROGER H. MITCHELL§ AND RUSLAN P. LIFEROVICH¶ Department of Geology, Lakehead University, 955 Oliver Road, Thunder Bay, Ontario P7B 5E1, Canada ABSTRACT The crystal structure of members of the pyrophanite–ecandrewsite solid-solution series, Mn1–xZnxTiO3 (0.1 ≤ x ≤ 0.8 apfu), synthesized by ceramic methods in air at ambient pressure, has been characterized by Rietveld analysis of powder X-ray-diffrac- tion patterns. All of these compounds crystallize with the ilmenite structure and adopt space group R3.¯ The maximum solubility of Zn in MnTiO3 is considered to be ~0.8 apfu Zn, as compounds with greater Zn content do not form. Data are given for cell dimensions and atom coordinates, together with bond lengths, volumes and distortion indices for all coordination polyhedra. Within the solid-solution series, unit-cell parameters and volumes decrease linearly from those of MnTiO3 with increasing ZnTiO3 content. All compounds consist of distorted AO6 and TiO6 polyhedra, and, in common with pyrophanite and ilmenite, the former are the more distorted. Displacement of (Mn,Zn) and Ti from the centers of their coordination polyhedra increases with increasing Zn content. The interlayer distance across the vacant octahedral site in the TiO6 layer decreases with entry of the smaller Zn cation into the AO6 octahedra. The synthetic titanates are analogues of iron-free manganoan ecandrewsite and zincian pyrophanite occurring in peralkaline syenites at Pilansberg, in South Africa, and Poços de Caldas, in Brazil.

    GEOLOGICAL SURVEY Mineralogical Determination of Heavy Minerals In

    UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Mineralogical determination of heavy minerals in beach sands, Cape Mountain district, Seward Peninsula, Alaska Ching Chang Woo Open-File Report 89-1 55 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature Mineralogical determination of heavy minerals in beach sands, Cape Hountain district, Seward Peninsula, Alaska by Ching Chang Woo INTRODUCTION Most of the tin that has been produced in the United States has come from the Seward Peninsula, Alaska. Streams in the Cape Mountain district produced 700 tons of tin concentrate from 1933 to 1941 (Heide and Sanford, 1948). At Cape Mountain, located at the westernmost tip of the Seward Peninsula, a 78.8 Ma, coarse-grained, biotite granite intruded a Mississippian limestone which is In thrust contact with Precambrian slates, silitites, and grayuackes (Sainsbury, 1972). Village Creek, which flows along the granite-limestone contact, drains the eastern slope of Cape Mountain and has produced placer cassiterite originally derived from lodes near the limestone-granite contact. Placer deposits from Cape Creek produced coarse grained cassiterite and occasional cassiterite boulders that weigh more than 30 pounds (B. Reed, Written communication, 1988). A barrier beach extends north, then northwest from Cape Mountain, The U.S. Bureau of Mines drilled the gravel bars in the district to evaluate the potential for finding new resources; they found some additional tin reserves along creeks of the northern slope of Cape Mountain (Heide and Sanford, 1948; Mulligan and Thorne, 1959). Samples analyzed in this study were collected at the mouth of' Village Creek and along the beach or in the back-beach area of off-shore bars, as indicated in Table 1.
