  • Oxygenic Bismuth Minerals in the NE Part of the Karkonosze Pluton (West Sudetes, SW Poland)
    Acta Geologica Polonica, Vol. 68 (2018), No. 4, pp. 537–554 DOI: 10.1515/agp-2018-0016 Oxygenic bismuth minerals in the NE part of the Karkonosze pluton (West Sudetes, SW Poland) ANDRZEJ KOZŁOWSKI and WITOLD MATYSZCZAK* Faculty of Geology, University of Warsaw, Żwirki i Wigury 93, PL-02-089 Warszawa, Poland. *E-mail: [email protected] ABSTRACT: Kozłowski, A. and Matyszczak, W. 2018. Oxygenic bismuth minerals in the NE part of the Karkonosze pluton (West Sudetes, SW Poland). Acta Geologica Polonica, 68 (4), 537–554. Warszawa. The study presents fifteen oxygen-bearing secondary minerals of bismuth from the north-eastern part of the Variscan Karkonosze granitoid pluton in the northern zone of the Bohemian massif. The minerals were inves- tigated by optical, electron microprobe, classic chemical, XRD, IR absorption and fluid inclusion methods. The late, very low temperature epithermal solutions most probably caused formation of sillénite, kusachiite, bismoclite, bismutite, beyerite, kettnerite, pucherite, schumacherite, namibite and eulytite. Solutions dominated by supergene (meteoric) waters were the parents for bismite, russellite, koechlinite, ximengite and walpurgite. The paper also contains information on early research on the investigated minerals. Key words: Karkonosze granitoid pluton; Bismuth minerals; Secondary minerals; Oxidation; Vein; Pegmatite.

  • Design Rules for Discovering 2D Materials from 3D Crystals
    Design Rules for Discovering 2D Materials from 3D Crystals by Eleanor Lyons Brightbill Collaborators: Tyler W. Farnsworth, Adam H. Woomer, Patrick C. O'Brien, Kaci L. Kuntz Senior Honors Thesis Chemistry University of North Carolina at Chapel Hill April 7th, 2016 Approved: ___________________________ Dr Scott Warren, Thesis Advisor Dr Wei You, Reader Dr. Todd Austell, Reader Abstract Two-dimensional (2D) materials are championed as potential components for novel technologies due to the extreme change in properties that often accompanies a transition from the bulk to a quantum-confined state. While the incredible properties of existing 2D materials have been investigated for numerous applications, the current library of stable 2D materials is limited to a relatively small number of material systems, and attempts to identify novel 2D materials have found only a small subset of potential 2D material precursors. Here I present a rigorous, yet simple, set of criteria to identify 3D crystals that may be exfoliated into stable 2D sheets and apply these criteria to a database of naturally occurring layered minerals. These design rules harness two fundamental properties of crystals—Mohs hardness and melting point—to enable a rapid and effective approach to identify candidates for exfoliation. It is shown that, in layered systems, Mohs hardness is a predictor of inter-layer (out-of-plane) bond strength while melting point is a measure of intra-layer (in-plane) bond strength. This concept is demonstrated by using liquid exfoliation to produce novel 2D materials from layered minerals that have a Mohs hardness less than 3, with relative success of exfoliation (such as yield and flake size) dependent on melting point.

The name is in memory of Mario Gelosa (1947–2006) who first found the mineral. The mineral also occurs in the oxidized zones of the Old 25 and Wolfram pipes at Kingsgate, New South Wales, Australia. Both the mineral and its name have been approved by the IMA CNMNC (IMA 2009-022). Gelosaite occurs as yel- low, yellowish green, and pale blue, prismatic crystals with a white streak. It is transparent with an adamantine luster, non-fluorescent, brittle, and has a conchoidal fracture. Mohs hardness is ~3. The mineral is monoclinic, space group P21/n, with a = 5.8505(4), b = 9.0421(6), c = 13.917(1) Å, β = 100.42(1)°, V = 724.1(1) Å3, Z = 4 (yellow Su Senargiu crystal); a = 5.8570(5), b = 9.0517(8), c = 13.992(1) Å, β = 100.44(1)°, V = 729.5(1) Å3, Z = 4 (pale blue Su Senargiu crystal); a = 5.837(3), b = 9.040(5), c = 13.904(7) Å, β = 100.64(1)°, V = 721.0(6) Å3, Z = 4 (blue Kingsgate crystal).

  • NEW DATA on AGRICOLITE, BISMOCLITE, KOECHLINITE, and the BISMUTH ARSENATES Cr,Rrronn Fnononr,, H Araar D U Nioer Si,Ty, C Ambrid
    NEW DATA ON AGRICOLITE, BISMOCLITE, KOECHLINITE, AND THE BISMUTH ARSENATES Cr,rrronn FnoNonr,,H araard Unioer si,ty, C ambridge, M ass achus etls* ABSTRACT Agricolite is identical with eulytite. Rhagiteis identicalrvith atelestite. Arsenobismite from Tintic, Utah, is a valid species and a new locality atTazna", Bolivia, is noted. A new but un-named bismuth arsenate is briefly described and three localities are cited. Two new localities are cited {or both koechlinite and bismoclite. X-ray powder spacing data are tabulated for atelestite, arsenobismite. koechlinite. and for a new un-named bismuth arse- nate. IorNrrry oF AcRrcolrrE wrrH Eur-yrrrn Eulytite, BiaSiaOrz,occurs as well-developed isometric hextetrahedral crystals. The material usually is weakly birefringent, and has been thought to be only pseudo-isometric at ordinary conditions. Some crys- tals are internally divided into uniaxial segments,or show polysynthetic birefringent twinning lamellae. The optical anomalies have been de- scribed by Bertrand (1881). The r-ray powder difiraction effects, how- ever, are completely accounted for on the basis of a hextetrahedral structure, as shownby Menzer (1931),and any departurefrom isometric symmetry must be slight. The calculated specific gravity, 6.82, is con- siderably greater than the observedvalues. The writer obtained 6.61 ior yellow eulytite crystals and 6.63 for massiveagricolite (: eulytite), using a microbalance.Menzer obtained 6 6+0.2 and Rath (1869) gave 6.106 for eulytite. Agricolite of Frenzel (1373) has been thought to be a mono- clinic polymorph of eulytite. The supposed monoclinic character was based on very inconclusive evidence (see Groth cited by Frenzel (1873)). The writer examined several specimensof agricolite from both Schnee- berg and Johanngeorgenstadt,Saxony.
