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. -

Both minerals are triclinic, their structures are closely related to the parent structure, i.e. the 'tsumcorite type' (C2/m, Z = 2). The lower symmetry is caused by two different crysta,l-ch~mical requirements. Order :Bhenomen~+ o.f the hydrogen bonds cause the 'helmutwmklente type (PI, Z = 4), ordenng of Cu and Fe' IS responsible for the 'gartrellite type' (PI, Z = I). Rappoldite was found on samples from the Rappold mine near Schneeberg, Saxony, Gennany. The new species fonns red to red-brown prismatic and tabular crystals up to I mm long. Deale. = 5.28 g/cm3. 2Vz = 85(5r, nx = 1.85 (calc.), ny = 1.87(2) and nz = 1.90(2); dispersion is distinct with r > v; orientation is Y -II [120] and X - c.

Mottramite, Descloizite, and Vanadinite) in the Caldbeck Area of Cumberland
289 New occurrences of vanadium minerals (mottramite, descloizite, and vanadinite) in the Caldbeck area of Cumberland. By ART~VR W. G. KINGSBURu F.G.S., Dept. of Geology and Mineralogy, University Museum, Oxford, and J. HARTLnY, B.Sc., F.G.S., Dept. of Geology, University of Leeds. [Taken as read 10 June 1954.] Summary.--Four new occurrences of vanadium minerals are described. New X-ray powder data are given for descloizite and mottramite, and show appreciable differences. Evidence is brought that the original occurrence of mottramite was not at Mottram St. Andrew, Cheshire, but Pim Hill, Shropshire, and that most if not all specimens labelled Mottram St. Andrew or Cheshire really came from Pim Hill. ANADIUM minerals are rare in the British Isles, and only two V species, mottramite (Cu, Zn)PbV0tOH and vanadinite Pbs(VO4)aC1, have so far been recorded from a limited number of localities. We do not include the vanadiferous nodules from Budleigh Salterton in Devon, as the vanadiferous mineral has not been identified. Mottramite, supposedly from Mottram St. Andrew in Cheshire, was first described in 1876,1 but we have evidence (below, p. 293) that the locality was in fact Pim Hill in Shropshire. ~ Vanadinite has so far only been found at Leadhills and Wanlockhead in Scotland. Vauquelinite has been de- scribed from Leadhills and Wanlockhead,a but the specimens have since been shown to be mottramite. 4 As a result of our investigations in the Lake District, we have found several new localities in the Caldbeck area for raottramite, deseloizite, and vanadinite.

Preparation and Solubility of Hydroxyapatite

Gregory,* and W. E. Brown* Institute for Basic Standards, National Bureau of Standards, Washington, D.C. 20234 (August 2, 1968) Two portions of a syntheti c hydroxyapatite (HA), Ca" OH(PO'}J, full y characterized by x-ray, infrared, petrographi c, and chemi cal anal yses, were heated at 1,000 °C in air and steam atmospheres, respectively. Solubility isotherms for these two samples in the syste m Ca(OH}2 -H3PO,-H20 were determined in the pH range 5 to 7 by equilibrating the solids with dilute H3 PO. solutions. Both sam ples of HA disso lved stoichiometrically. The activity products (Ca + +)'( OH - ) (pO~f' and their standard errors-obtained by a least squares adjustment of the measurements (Ca and P concentrations and pH of the saturated solutions) subject to the conditions of electroneutralit y, constancy of the activity product, and stoichiometric dissolution - were 3.73 ± 0.5 x 10- 58 for the steam-h eated HA and 2_5, ± 0.4 x 10- 55 for the air-heated HA. Allowance was made in the calculations for the presence of the ion pairs [CaHPO. lo and [CaH2P04 1+ The hi gher solubility product for the air-heated HA is as cribed either to a change in the heat of formation brought about by partial dehydration or to a state of fine subdivision resulting from a disproportionation reacti on_ The solubility product constant s were used to cal culate the points of intersection (i.e_, sin gular points) of the two HA solubility isot herms with the isotherms of CaHPO. -
Cu-Rich Members of the Beudantite–Segnitite Series from the Krupka Ore District, the Krušné Hory Mountains, Czech Republic
Journal of Geosciences, 54 (2009), 355–371 DOI: 10.3190/jgeosci.055 Original paper Cu-rich members of the beudantite–segnitite series from the Krupka ore district, the Krušné hory Mountains, Czech Republic Jiří SeJkOra1*, Jiří ŠkOvíra2, Jiří ČeJka1, Jakub PláŠIl1 1 Department of Mineralogy and Petrology, National museum, Václavské nám. 68, 115 79 Prague 1, Czech Republic; [email protected] 2 Martinka, 417 41 Krupka III, Czech Republic * Corresponding author Copper-rich members of the beudantite–segnitite series (belonging to the alunite supergroup) were found at the Krupka deposit, Krušné hory Mountains, Czech Republic. They form yellow-green irregular to botryoidal aggregates up to 5 mm in size. Well-formed trigonal crystals up to 15 μm in length are rare. Chemical analyses revealed elevated Cu contents up 2+ to 0.90 apfu. Comparably high Cu contents were known until now only in the plumbojarosite–beaverite series. The Cu 3+ 3+ 2+ ion enters the B position in the structure of the alunite supergroup minerals via the heterovalent substitution Fe Cu –1→ 3– 2– 3 (AsO4) (SO4) –1 . The unit-cell parameters (space group R-3m) a = 7.3265(7), c = 17.097(2) Å, V = 794.8(1) Å were determined for compositionally relatively homogeneous beudantite (0.35 – 0.60 apfu Cu) with the following average empirical formula: Pb1.00(Fe2.46Cu0.42Al0.13Zn0.01)Σ3.02 [(SO4)0.89(AsO3OH)0.72(AsO4)0.34(PO4)0.05]Σ2.00 [(OH)6.19F0.04]Σ6.23. Interpretation of thermogravimetric and infrared vibrational data is also presented. The Cu-rich members of the beudan- tite–segnitite series are accompanied by mimetite, scorodite, pharmacosiderite, cesàrolite and carminite. -
