    American Mineralogist, Volume 91, pages 1839–1846, 2006 New insight into crystal chemistry of topaz: A multi-methodological study G. DIEGO GATTA,1,* F. NESTOLA,2,3 G.D. BROMILEY,4 AND A. LOOSE5 1Dipartimento di Scienze della Terra, Università degli Studi di Milano, Via Botticelli 23, I-20133 Milano, Italy 2Dipartimento di Mineralogia e Petrologia, Università degli Studi di Padova, Corso Garibaldi 37, I-35137 Padova, Italy 3Bayerisches Geoinstitut, Universität Bayreuth, Universitätsstrasse 30, D-95447 Bayreuth, Germany 4Department of Earth Sciences, Cambridge University, Downing Street, Cambridge CB2 3EQ, U.K. 5 Forschungszentrum Jülich, D-52425 Jülich, Germany ABSTRACT The crystal chemistry of a natural topaz [with OH/(OH + F) < 0.5] was reinvestigated by means of laser ablation inductively coupled plasma mass spectroscopy, single-crystal X-ray diffraction (at 298 K) and neutron diffraction (at 298 and 10 K), and polarized infrared spectroscopy to deÞ ne unambiguously the real symmetry of topaz, the location of the proton and its thermal displacement parameters at room and low temperatures, the hydrogen-bonding and the vibration modes (stretch- ing and bending) of the OH dipole. X-ray and neutron structural reÞ nements allow us to infer that the crystal structure of natural topaz with OH/(OH + F) < 0.5 can be described with the Pbnm space group. Violating reß ections, found in the previous investigations and in this study, are likely due to Renninger effect (double diffraction phenomenon). The nuclear density Fourier map shows that the proton is located at Wyckoff 8d position and the reÞ ned coordinates are: x = 0.495(2), y = 0.252(1), z = 0.1629(7).

  • A Specific Gravity Index for Minerats
    A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951).

  • CONTRIBUTIONS to the MINERALOGY of NORWAY By
    NORSK GEOLOGISK TIDSSKRIFT 41 CONTRIBUTIONS TO THE MINERALOGY OF NORWAY No. 9. On the occurrence of two rare phosphates in the Ødegården Apatite mines, Bamble, South Norway l. A V ARIETY OF WOODHOUSEITE 2. WHITLOCKITE By RoGER D. MoRTOK, B.Sc., Ph. D., F.G.S. (Mineralogisk-Geologisk Museum, University of Oslo, Norway.l) Abs t rac t. A description is given of varieties of woodhouseite and whit­ lockite found in specimens from the apatite-rich veins cutting the Precambrian rocks at Ødegårdens verk, Bamble, S. Norway. The minerals occur, together with quartz, in pockets within a matrix of chlor-hydroxy-oxyapatite. Physical and optical data are given for both minerals, together with x-ray powder dif­ fraction data. A semi-quantitative spectrographic analysis of the whitlockite is included. The woodhouseite is a purple variety with lattice dimensions of ah 7,001, ch 16,265, cja 2,325, ar 6,76 and L a 62° 22'; its optical constants are Ne = 1,669 ( ±0,003), l\0 = 1,662 ( ± 0,003), Ne -N0 0,007 ( ± 0,003), uniaxial positive (or occasionally biaxial with 2V of l o o to 20°). An unidentified alteration product after woodhouseite is also described. The whitlockite is a green variety, r:ontaining approximately 0,3% V205, with optical constants: N0 = 1,620 ( ± 0.003), Ne = 1,623 ( ± 0,003), Ke - N0 0,003 ( ± 0,003), uniaxial negative. It is concluded that the minerals in these pockets represent either final residual products of crystallisation within the apatite vein or that they were formed during a later period of metamorphism, metasomatism and hydro­ thermal activity which may have affected the apatite veins.

  • Champion Sillimanite Mine, White Mountain Mono County, California by J
    Champion Sillimanite Mine, White Mountain Mono County, California by J. F. (Fen) Cooper DESCRIPTION OF AREA: The Champion Sillimanite Mine is located on the west flank of White Mountain about 20 miles north of Bishop on the western face of White Mountain in Jeffrey Mine Canyon. The mine is about 3 miles east of White Mountain Ranch and lies at an altitude of about 8,000 feet. It is in section 13, T. 3S., R. 33E., M.D.M. and is at latitude 37o 56’ 20” North and longitude 118o 12’ 00” East on page 113 of Delorme’s Northern California Atlas and Gazetteer. The access road to the old mule corrals and the location of the main workings are shown on the map but none of the trails or secondary roads are. The Champion Mine is only accessible by foot over the old mule trails due to the steep and rugged nature of the terrain. The only “maintained” road is the one that leads from White Mountain Ranch to the site of the old mule corrals and this is usually in poor shape. Occasionally the section of the road that leads into the area of the old Moreau Claims is graded and passable but this is infrequent and this section of road usually has several washouts and is impassible to all but foot traffic. In the upper sections of Jeffrey Mine Canyon no roads were built and all the supplies needed to sustain the mining operation were carried in by mule and these trails are the only way in.

Arsrru.cr Walthierite and huangite, two new members of the alunite group, were found in the Tambo mining district and the El Indio gold, silver, and copper deposit, Coquimbo region, Chile, respectively.Walthierite, Bao,!o ,Al3(SOo)r(OH)u,is associatedwith alunite,jarosite, baite, quartz, and pyrite in veins. Huangite, Caortro rAlr(SOo)r(OH)6, coexists with kaolin- ite, pyrite, and woodhouseitein altered wall rocks. The new alunite group minerals have spacegroup R3m, Z: 6, with lattice parameters4 : 6.992(4)A,, c : 34.443(8)A, D*. : 3.02 g/cm3for walthierite, and a: 6.983(5)A, c : 33.517(9)A, D-,.: 2.80 g/cm3 for huangite.The strongestlines in the X-ray powder diffraction patterns are (d, I, hkl): 5.73, (50),(006);3.49,(55),(l l0); 2.98,(100),(ll6); 2.283,(80),(1,0,14);1.909,(70),(0,0,18) for walthierite,and 4.91,(75),(014);2.97,(100),(116); 2.231,(51),(l,0,la); 1.899,(a3),(306); 1.375,(40),(3,1,14)for huangite.Both mineralsshow superlatticereflections with c that is double that of alunite, resulting from the ordering of cations and vacancieson l2-fold coordinated M sites.
