  • A Review on Historical Earth Pigments Used in India's Wall Paintings
    heritage Review A Review on Historical Earth Pigments Used in India’s Wall Paintings Anjali Sharma 1 and Manager Rajdeo Singh 2,* 1 Department of Conservation, National Museum Institute, Janpath, New Delhi 110011, India; [email protected] 2 National Research Laboratory for the Conservation of Cultural Property, Aliganj, Lucknow 226024, India * Correspondence: [email protected] Abstract: Iron-containing earth minerals of various hues were the earliest pigments of the prehistoric artists who dwelled in caves. Being a prominent part of human expression through art, nature- derived pigments have been used in continuum through ages until now. Studies reveal that the primitive artist stored or used his pigments as color cakes made out of skin or reeds. Although records to help understand the technical details of Indian painting in the early periodare scanty, there is a certain amount of material from which some idea may be gained regarding the methods used by the artists to obtain their results. Considering Indian wall paintings, the most widely used earth pigments include red, yellow, and green ochres, making it fairly easy for the modern era scientific conservators and researchers to study them. The present knowledge on material sources given in the literature is limited and deficient as of now, hence the present work attempts to elucidate the range of earth pigments encountered in Indian wall paintings and the scientific studies and characterization by analytical techniques that form the knowledge background on the topic. Studies leadingto well-founded knowledge on pigments can contribute towards the safeguarding of Indian cultural heritage as well as spread awareness among conservators, restorers, and scholars.

  • Fluid Inclusions in Fibrous and Octahedrally-Grown Diamonds
    FLUID INCLUSIONS IN FIBROUS AND OCTAHEDRALLY-GROWN DIAMONDS by Evan Mathew Smith A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate and Postdoctoral Studies (Geological Sciences) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) March 2014 © Evan Mathew Smith, 2014 Abstract My thesis puts forth new models for diamond formation that explain the difference between octahedral and fibrous diamond growth, as well as the difference between octahedral diamond growth in the lithospheric and the sublithospheric mantle. Diamond growth in the mantle involves reactions between carbon-bearing fluid and the host rocks it infiltrates. This fluid is sometimes included in diamond. Fluids in dendritically-grown, fibrous diamonds from Wawa, Superior craton, were analysed in a novel way, using transmission X-ray diffraction. The technique allows bulk analysis of daughter minerals within fluid inclusions. The mineralogy, major and trace elements, Sr isotopes, volatiles, and nitrogen characteristics of the hydrous saline–high-Mg carbonatitic fluid in these Archean diamonds strongly resemble those of Phanerozoic fibrous diamonds. This implies that some mantle processes, including the formation of fibrous diamonds, can be extended unvaryingly back to 2.7 Ga. Fluid equilibrated with octahedrally-grown diamonds from the Siberian, Kaapvaal, and Congo cratons is trapped in healed fractures in the diamonds. They contain anhydrous CO2–N2 fluid inclusions with 40±4 mol% N2 and inclusions of former silicate melt that had an original N2 content of ~0.1 wt%, as shown by Raman, electron microprobe, and microthermometry analyses. The liberation of N2 from the convecting mantle is proposed to be controlled by increasing oxygen fugacity that destabilizes host phases.

  • 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).

Inorganic Materials Research Program, School of Physical and Chemical Science, Queensland University of Technology A THESIS SUBMITED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY OF THE QUEENSLAND UNIVERSITY OF TECHNOLOGY 2004 2 Toss another rock on the Raman… 3 KEYWORDS Annabergite Aragonite Arupite Baricite Cerussite Erythrite Hörnesite Infrared Spectroscopy Köttigite Minerals Parasymplesite Raman Spectroscopy Solid Solutions Strontianite Vibrational Spectroscopy Vivianite Witherite 4 ABSTRACT This thesis focuses on the vibrational spectroscopy of the aragonite and vivianite arsenate minerals (erythrite, annabergite and hörnesite), specifically the assignment of the spectra. The infrared and Raman spectra of cerussite have been assigned according to the vibrational symmetry species. The assignment of satellite bands to 18O isotopes has been discussed with respect to the use of these bands to the quantification of the isotopes. Overtone and combination bands have been assigned according to symmetry species and their corresponding fundamental vibrations. The vibrational spectra of cerussite have been compared with other aragonite group minerals and the differences explained on the basis of differing chemistry and crystal structures of these minerals. The single crystal spectra of natural erythrite has been reported and compared with the synthetic equivalent. The symmetry species of the vibrations have been assigned according to single crystal and factor group considerations. Deuteration experiments have allowed the assignment of water vibrational frequencies to discrete water molecules in the crystal structure. Differences in the spectra of other vivianite arsenates, namely annabergite and hörnesite, have been explained by consideration of their differing chemistry and crystal structures.

The relations between the unit cells of phosphophyl- lite and hopeite are simple and are given in the description of the former. Parahopeite and anapaite have very similar unit cells, their differences being due solely to the variation in cation content. The relation between the cells of the triclinic members and the monoclinic and orthorhombic membersis not clear. The addition of one or more molecules of water to each crystallizing molecule must be accompanied by a completely new bonding arrange- ment, for there is no recognizablerelation between the unit cells of the members of the various families and there is no single factor of the unit cells which varies with the water variation. Thus it is impossible to relate the unit cells of the various families, although there is a definite relation 787 788 C. W. WOLFE between the cell volumes and the number of water molecules.

  • AFMS Mineral List 2003
    American Federation Of Mineralogical Societies AFMS Mineral Classification List New Edition Updated for 2003 AFMS Publications Committee B. Jay Bowman, Chair 1 Internet version of Mineral Classification List. This document may only be downloaded at: http://www.amfed.org/rules/ Introduction to the Mineral Classification List The AFMS Rules Committee voted to eliminate the listing in the Rulebook of references for mineral names except for the AFMS Mineral Classification List. Exhibitors are encouraged to use the AFMS List when exhibiting in the B Division (Minerals). If the mineral they are exhibiting is not on the AFMS List they should note on the Mineral list they present to the judging chairman which reference they did use for the information on their label. The Regional Rules Chairs have been asked to submit names to be added to the list which will be updated with addendum’s each year. In a few years the list should represent most of the minerals generally exhibited out of the 4200+ now recognized by the IMA. This list follows the Glossary of Mineral species which is the IMA approved names for minerals. When the Official name of the mineral includes diacritical mark, they are underlined to indicate they are the IMA approved name. Where usage of old names has been in use for years they have been included, but with the approved spelling underlined following it. The older spelling will be accepted for the present so exhibitors will not have to correct there present label. This list may not contain all mineral species being exhibited. Exhibitors are encouraged to submit names to be added to the list to the Rules committee.
