GASPEITE, (Ni, Mg, Fe) (CO), a NEW CARBONATE from the GASPE PENINSULA, QUEBEC D THE AMERICAN MINERALOGIST, VOL. 51, MAY_JUNE, 1966 GASPEITE, (Ni, Mg, Fe) (CO), A NEW CARBONATE FROM THE GASPE PENINSULA, QUEBEC D. W. Konrs awn J. L. Ronoe, ResearchDepartment, The NezuJersey Zinc Company,Palmerton, pennsyhtan,ia. Aesrnacr A new nickel carbonate mineral was found as a vein enclosed in siliceous dolomite in the Gaspd Peninsula, Quebec. Magnesium and to a lesser extent, iron, carbonates are in solid solution with the nickel carbonate. The name gaspeite has been selected for the nickel carbonate end member, the new mineral being designated as magnesian gaspeite. It occurs associated with small amounts of millerite, niccolite, annabergite and gersdorffite. Magnesian gaspeite occurs as light green crystals up to 0.5 mm in length. The mineral is insoluble in water and very slowly soluble in nitric or hydrochloric acids. Its hardness is about 4.5 to 5; density 3.71+ 0.0r g/cm,; vitreous to dull luster; yeilow-greenstreak; an un- even fracturel good rhombohedral cleavage.rt is uniaxial negative, with o: 1.g3* 0.01 and e:1.61+0.01; A:0.22. X-ray analysis shows that the crystals are rhombohedral with the followine character_ istics:o:4.621+0.002; c:14.93+0.02A; C:3.231+0,006; o,r:5.65+O.0iA: o:48" 18'3/*5'5'; volume 276.0f 0.9 AB; cer contents3 [(Nio.ssMgo.suFeo.ru)(cor)r]in the hexagonal unit.

INrnonucrroN An unusual light green mineral, occurring in a massive two-foot wide vein enclosedin a varicolored siliceousdolomite of Middle Silurian age, was found by the New Jersey Zinc Exploration Co. (Canada), Ltd., during an investigation of Lemieux Township, Gasp6 Nord County, Gasp6Peninsula, Quebec, Canada. The sampleswere submitted to the ResearchDepartment of The New Jersey Zinc Company at Palmerton, pennsylvania, where r_ray, wet chemical, spectrographic, infrared, differential thermal analysis, and petrographicanalyses suggested it to be a previouslyundescribed nickel, magnesium,iron carbonate.The name gaspeitehas beenselected for the nickel carbonate end member, the lew mineral being designated as magnesiangaspeite. rts compositionis'(Nio.neMgo.soFeo.ro) (coe)2.

W. KOHLSAND J. L. RODDA amountsof annabergite,magnesite and dolomite' Enclosedin the magne- sian gaspeiteare a small amount of serpentineand a (Cr, Al) spinel (5 to 10/6 and,less than 5/6, respectively). Well-formed crystals of millerite (NiS), niccolite (NiAs), annabergite (Nia(AsOr)z'8HzO),gersdorffite (NiAsS) and magnesite (MgCOa) are found outside of the vein in the buff siliceousdolomite. The vein did not crop out but was exposedby a bulldozer during road building operationsin the area.The formation in which it occursrests un- conformably on the Shickshock Series, a hornblende-chlorite schist, of Cambrian or Precambrianage and is overlain by a qtartzite of Middle Silurian age. Serpentinized plugs of post Middle Silurian and pre-Middle Devonian age (McGerrigle, 1954)were intruded into the siliceousdolomite. NftNBnar SnpenarroN Magnesiangaspeite crystals were isolatedby crushingthe sampleand separatingthe -100 to *150 mesh fraction on a Frantz isodynamic magnetic separator.It separatedrather sharply between0.40 and 0'45 ampere with cross slope and longitudinal slope of 15o and 30o, respec- tively. This fractionwas further cleanedwith methyleneiodide (sp. gr.: 3.33). The heavy fraction was retained and one gram was submitted for chemicalanalysis. Pnvsrc.q.reNl Optrclr- PnopBntrns Magnesian gaspeiteoccurs as light green rhombohedral crystals up to 0.5 mm in length. The mineral has a vitreous to dull luster, yellow-green streak, and uneven fracture, and good rhombohedralcleavage (1011)' Its hardnessis 4.5 to 5. The specificgravity of -100 to *150 mesh magnesian gaspeite crystals, determined by the pycnometer method using keroseneas the immersion liquid, is 3.71+0.01; the calculated specificgravity is 3.748. Magnesiangaspeite is light greenin transmitted light. The indices of refraction, determined by the immersion method,l were o:1.83+0'01 ande :1.61+0.01 ; A:0.22.It is uniaxialnegative.

The spectrum of magnesian gaspeite includes three major absorption bands 23,v2 a.nd va at 7.00, 11.42 and 13.32microns, respectively. A com- parison of the spectrum of magnesiangaspeite and other selectedcalcite- group carbonatesobtained by Adler and Kerr (1963)is given in Table 1. An examination of Table 1 indicates that the infrared spectrum of magnesiangaspeite bears a closer resemblanceto those of magnesite and smithsonite than to those of the other minerals of the calcite group.

Of the cations, nickel ion is main source for the electronic features as a principal constituent in the mineral where as the bands in IR and Raman spectra are due to the vibrational processes in the carbonate ion as an entity. The combination of electronic absorption spectra and vibrational spectra (including near-infrared, FTIR and Raman) of magnesian gaspeite 2- are presented and explained the cation co-ordination and the behaviour of CO 3 anion in the Ni-Mg carbonate. The electronic absorption spectrum consists of three broad and intense bands at 8130, 13160 and 22730 cm-1 due to spin-allowed transitions and two weak bands at 20410 and 30300 cm -1 are assigned to spin- forbidden transitions of Ni 2+ in an octahedral symmetry.

Schafer Open-File Report 81-1174 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards 1981 The Ford-Fleischer File of Mineralogical References 1978-1980 Inclusive by Michael Fleischer and Constance M. Schafer In 1916, Prof. W.E. Ford of Yale University, having just published the third Appendix to Dana's System of Mineralogy, 6th Edition, began to plan for the 7th Edition. He decided to create a file, with a separate folder for each mineral (or for each mineral group) into which he would place a citation to any paper that seemed to contain data that should be considered in the revision of the 6th Edition. He maintained the file in duplicate, with one copy going to Harvard University, when it was agreed in the early 1930's that Palache, Berman, and Fronde! there would have the main burden of the revision. A number of assistants were hired for the project, including C.W. Wolfe and M.A. Peacock to gather crystallographic data at Harvard, and Michael Fleischer to collect and evaluate chemical data at Yale. After Prof. Ford's death in March 1939, the second set of his files came to the U.S. Geological Survey and the literature has been covered since then by Michael Fleischer. Copies are now at the U.S. Geological Survey at Reston, Va., Denver, Colo., and Menlo Park, Cal., and at the U.S.

Kostov University of Mining and Geology “St. Ivan Rilski”, Sofia 1700; [email protected] ABSTRACT. A dual crystal structural and paragenetic principle (Kostov, 1993; Kostov, Kostov, 1999) Has been applied to a rational classification of tHe carbonate minerals. Main divisions (associations) are based on geocHemically allied metals in tHe composition of tHese minerals, and subdivisions (axial, planar, pseudoisometric and isometric types) on tHeir overall structural anisometricity. The latter provides botH structural similarity and genetic information, as manner of crystal groWtH in geological setting under different conditions of crystallization. The structural anisometricity may conveniently be presented by tHe c/a ratio of tHe minerals WitH HigH symmetry and by tHe 2c/(a+b), 2b/(a+c) and 2a/(b+c) ratios for tHe loW symmetry minerals. The respective ratios are less, nearly equal, equal or above 1.00. The unit cell or sub-cell and tHe corresponding structures are denoted as axial or A-type, pseudo-isometric or (I)-type, isometric or I-type and planar or P- type, notations WHicH correspond to cHain-like, frameWork and sHeet-like structures, respectively ino-, tecto- and pHyllo-structures. The classification includes tHree geocHemical assemblages among tHe carbonate minerals – Al-Mg-Fe(Ni,Co,Mn), Na-Ca-Ba(К)-REE and Zn-Cu-Pb(U).

These new instruments are the focus of the lead article in this issue, by Christopher Welbourn, Martin Cooper, and Paul Spear. The natural-diamond rings shown here contain round brilliants weighing a total of 5.19 ct (top), 4.38 ct (left),5.36 ct (bottom), and (right)6.78 ct with a 3.49 ct yellow emerald-cut diamond.

  • A Mineralogical Field Guide for a Western Tasmania Minerals and Museums Tour
    MINERAL RESOURCES TASMANIA Tasmania DEPARTMENTof INFRASTRUCTURE, ENERGY and RESOURCES Tasmanian Geological Survey Record 2001/08 A mineralogical field guide for a Western Tasmania minerals and museums tour by R. S. Bottrill This guide was originally produced for a seven day excursion held as part of the International Minerals and Museums Conference Number 4 in December 2000. The excursion was centred on the remote and scenically spectacular mineral-rich region of northwestern Tasmania, and left from Devonport. The tour began with a trip to the Cradle Mountain National Park, then took in visits to various mines and mineral localities (including the Dundas, Mt Bischoff, Kara and Lord Brassey mines), the West Coast Pioneers Memorial Museum at Zeehan and a cruise on the Gordon River. A surface tour of the copper deposit at Mt Lyell followed before the tour moved towards Hobart. The last day was spent looking at mineral sites in and around Hobart. Although some of the sites are not accessible to the general public, this report should provide a guide for anyone wishing to include mineral sites in a tour of Tasmania.
