X-Ray Rietveld and 57Fe Mössbauer Study of Babingtonite from Kouragahana, Shimane Peninsula, Japan
Journal of MineralogicalBabingtonite and from Petrological Kouragahana, Sciences, Shimane Volume Peninsula, 108, pageJapan 121─ 130, 2013 121 X-ray Rietveld and 57Fe Mössbauer study of babingtonite from Kouragahana, Shimane Peninsula, Japan * * ** Masahide AKASAKA , Takehiko KIMURA and Mariko NAGASHIMA *Department of Geoscience, Graduate School of Science and Engineering, Shimane University, 1060 Nishikawatsu, Matsue 690-8504, Japan **Department of Earth Science, Graduate School of Science and Engineering, Yamaguchi University, Yamaguchi 753-8512, Japan Babingtonite from Kouragahana, Shimane Peninsula, Japan, was investigated using electron microprobe, X-ray Rietveld, and 57Fe Mössbauer spectral analyses to characterize its chemical compositions, crystal structure, oxi- dation state of Fe, and distribution of Fe between two crystallographically independent octahedral Fe1 and Fe2 sites. _ The_ Kouragahana babingtonite occurs as single parallelohedrons with {100}, {001}, {001}, {111}, {110}, and {101} and sometimes shows penetration twinning. Both normal and sector-zoned crystals occur. Babing- tonite crystals with sector zoning consist of sectors relatively enriched in Fe and of sectors enriched in Mg, Mn, and Al. Babingtonite also shows compositional zoning with higher Fe2+ and Al core and higher Fe3+ and Mn 2+ rim. The average Fe content of the babingtonite without sector zoning is similar to the Fe -rich sector of the sector-zoned babingtonite. The chemical formula based on the average composition of all analytical data (n = 2+ 3+ - 193) is [Na0.01(2)Ca2.01(2)] [Mg0.11(4)Mn0.09(3)Fe0.76(7)Fe_ 0.93(5)Ti0.01(1)Al0.06(5)]Si5.01(4)O14(OH). X ray Rietveld refinement was carried out using a model of space group P1. -
CREEDITE from NEVADA Wrrrrrlr F. Fosnac,L Uni.Ted. States Ivati.Onal
CREEDITE FROM NEVADA WrrrrRlr F. Fosnac,l Uni.ted.States IVati.onal Muspum. The mineial creedite was first found by Esper S. Larsen in the fluorite mines of Wagon Wheel Gap, CreedeQuadrangle, Colorado, and describedby Larsen2and Wells as a new mineral speciesof the composition CaSOn.2CaF z. 2AI(F,OH)a. 2HzO. Later, better ma- terial was obtained and the mineral further investigated by the present writerr confirming the composition as found by Wells and determining the crystal symmetry and elements.The mineral was found to be monoclinic. Several crystal habits were found, all pris- matic but differing somewhat in the relative sizes of the terminaL faces. The mineral is associated with fluorite or embedded in a white halloysite clay. During geological field work for the U. S. Geological Survey in the Tonopah Quadrangle,Nevada, Mr. StanleyH. Cathcart visited the small gold camp of Granite (now abandoned), northwest of Tonopah in the northwestern corner of the Tonopah quadrangle and collected some specimensof the high grade ore found in the small veins of the district. These specimens showed scattered bunchesof a colorlessprismatic mineral which were determined by Dr. Clarence S. Ross, from their optical properties, to be creedite. The specimens were then turned over to the present writer for further study and are now in the collections of the U. S. National Museum (No.96489). The two specimens suggest that the gold bearing deposits of Granite are fluorite-quartz veins with free gold. The specimensare from the oxidized zone and are discolored by a clayey manganese wad. Visible flakes of gold are embedded both in the wad and in the fluorite. -

Bauer, 1971, pp. 231-234 in: San Luis Basin (Colorado), James, H. L.; [ed.], New Mexico Geological Society 22nd Annual Fall Field Conference Guidebook, 340 p. This is one of many related papers that were included in the 1971 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

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. -
