    1 HIGHLIGHTS AND BREAKTHROUGHS 2 Sapphire, a not so simple gemstone 3 F. LIN SUTHERLAND1* 4 1Geoscience, Australian Museum, 1 William Street, Sydney, NSW 2010, Australia. 5 *E-mail: [email protected] 6 Abstract: Sapphire is a gemstone of considerable reach and is much researched. It still delivers scientific surprises, as exemplified by a 7 recent paper in American Mineralogist that re-interprets the origin of needle-like rutile inclusions that form “silk” in sapphires. 8 Understanding of variations in sapphire genesis continues to expand. Keywords: Sapphire, inclusions, trace elements, genesis 9 Sapphire as a gem variety of corundum has wide use in the gem trade as one of the more historically valuable colored gem stones 10 (CGS) and is mined from a great variety of continental gem deposits across the world. A masterly compendium on this gemstone and its 11 ramifications is recently available (Hughes 2017). As a gem, sapphire ranges through all the colors of corundum, except where 12 sufficient Cr enters its α-alumina crystal structure and causes the red color of the variety ruby. Sapphire, as a key pillar in a wide 13 economic network of gem enhancing treatments, jewelry and other manufacturing enterprises, has elicited numerous scientific and 14 gemological enquiries into its internal nature and natural genesis and subsequent treatments. A further use of sapphire as a synthetic 15 material with a great variety of purposes also has triggered a proliferation of detailed studies on its growth, properties and other element 16 substitutional effects (Dobrovinski et al. 2009). Even with this vast range of studies, this apparently simple gemstone still yields 17 controversies and breakthroughs in understanding its genetic formation.

  • Do Zircon and Monazite Consistently Record Garnet Growth in High-Grade Rocks?
    Geophysical Research Abstracts Vol. 21, EGU2019-5915-1, 2019 EGU General Assembly 2019 © Author(s) 2019. CC Attribution 4.0 license. Do zircon and monazite consistently record garnet growth in high-grade rocks? Lorraine Tual (1,2), Ellen Kooijman (1), Melanie Schmitt (1), and Matthijs Smit (2) (1) Department of Geosciences, Swedish Museum of Natural History, Stockholm, Sweden ([email protected]), (2) Department of Earth, Ocean, and Atmospheric Sciences, University of British Columbia, Vancouver, Canada Garnet Lu-Hf ages are used to monitor the systematics of rare earth elements (REE) and age record in accessory minerals. We performed in-situ LA-(MC-)ICPMS U-(Th-)Pb dating and REE analysis on zircon and monazite in two contrasting high-grade rock samples: dry felsic granulite xenoliths from the Pamir, Tajikistan and fluid-rich, ultrahigh-pressure (UHP) migmatites from the Western Gneiss Region (WGR), Norway. In parallel, garnet from the same samples were subjected to REE analysis and dated by Lu-Hf. The datasets are compared to see whether, and to what extent, REE systematics in accessory phases can be correlated with garnet growth. Garnet in the hydrous UHP migmatite contains abundant zircon and monazite inclusions. The Gd/Yb values and U-(Th-)Pb ages of these inclusions show significant dispersion and do not systematically correlate. Highest Gd/Yb values occur at 420-410 and c. 420 Ma for monazite and zircon, respectively. Garnet in this rock yielded a Lu-Hf garnet bulk age of c. 422 Ma. The data obtained from the dry Pamir xenoliths show a different pattern. Accessory minerals grew in distinct pulses between 50 and 11 Ma, and indicate garnet growth between 42-37 Ma [1].

The genesis of the REE mineralization that occurred in the Gyemyeongsan Formation has been reported by previous researchers; theories include the fractional crystallization of alkali magma, magmatic hydrothermal alteration, and recurrent mineralization during metamorphism. In the Gyemyeongsan Formation, we discovered an allanite-rich vein that displays the paragenetic relationship of quartz, allanite, and zircon, and we investigated the chemistry and chronology of zircon obtained from this vein. We analyzed the zircon’s chemistry with an electron probe X-ray micro analyzer (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The grain size of the zircon is as large as 50 µm and has an inherited core (up to 15 µm) and micrometer-sized sector zoning (up to several micrometers in size). In a previous study, the zircon ages were not obtained because the grain size was too small to analyze.

  • REVERSIBLE COLOR MODIFICATION of BLUE ZIRCON by LONG-WAVE ULTRAVIOLET RADIATION Nathan D
    FEATURE AR ICLES REVERSIBLE COLOR MODIFICATION OF BLUE ZIRCON BY LONG-WAVE ULTRAVIOLET RADIATION Nathan D. Renfro Exposing blue zircon to long-wave ultraviolet (LWUV) radiation introduces a brown coloration, resulting in a somewhat unattractive, much less valuable gemstone. Common sources of accidental long-wave radiation that can affect mounted faceted blue zircons are tanning beds and UV lights used to apply acrylic fingernails. To determine if the LWUV-induced brown color in zircon is completely and easily reversible, quantitative UV-visible spectroscopy was used to measure the difference in absorption before and after LWUV exposure. This study explored the nature of the UV-induced color-causing defect to es- tablish whether subsequent exposure to visible light would completely restore the blue color. Spectro- scopic examination showed that blue color in zircon is due to a broad absorption band in the ordinary ray, starting at 500 nm and centered at approximately 650 nm. LWUV exposure induced absorption features, including a broad band centered at 485 nm that was responsible for the brown color. irconium silicate (ZrSiO ), better known as zir- cern was returning the stones to their vivid blue color. 4 con, is prized for its brilliance, vibrant color, One of these stones was reportedly restored to the de- Zand high clarity.

    Advances in Engineering Research, volume 104 7th International Conference on Mechatronics, Control and Materials (ICMCM 2016) Determination for structure and spectral characteristics of tabular beryl crystal HE Tao1, YIN Qiong2,* 1.Department of Biological and Environmental Engineering, Tianjin Vocational Institute, Tianjin, China 2.School of Mining Technology, Kunming Metallurgy College, Kunming, Yunnan, China *. Correspondence author Key words: Beryl, optical characteristics, inclusion, crystal, structure determination Abstract. Beryl in nature is columnar crystal generally; Beryl of clintheriform is quite rare. Different thermal luminescent effect occurs due to difference in geological and geochemical conditions for mineralization, and crystal lattice defects, impurity element content, radiation dose received from outside, thermal history and other items of beryl. There is negative crystal inclusion of ditrigonal scalenohedron in crystal, from an analysis of mineral deposit characteristics, inclusion, spectroscopic characteristics, optimization processing, artificial synthesis and other aspects of beryl. It can be concluded from the said analysis: Beryl crystal of clintheriform is huge and of perfect shape, high diaphaneity and high gemological value. And its peculiar paragenetic combination is of extremely high ornamental value. Causes of beryl Beryl is beryllium-aluminosilicate mineral. Colors of its varieties are different, pale blue (called as aquamarine), dark green (called as emerald), golden yellow (called as golden beryl), pink (called as morganite) and etc. The pale bluish green one is the most common. Beryl is of hexagonal cylindrical crystal generally and of various colors in most cases.
