    EVIDENCE FOR A SHALLOW REGIONAL SUBSURFACE DISCOt4TIN- UITY IN SOUTHERN MARE SERENITATIS. R.A. Young, Department of Geological Sciences, SUNY, Geneseo, N.Y. 14454. Several characteristics of south-central Mare Sereni tatis are unique to this basin and indicate that an unusual history may be recorded in the basin fill. Geologic evidence strongly supports a regional discontinuity beginning at depths greater than 40 m below the surface and extending to 250 m depths in some places. The following observations concerning the basin are pertinent to the discussion which follows: 1) The central porti on of Sereni tatis (brownish gray 1avas) represents much younger flooding than that which produced the older flows which ring the basin and form the highly cratered darker annulus of bluish gray lavas and mantling materials. A1 though the brownish gray lavas are approximately equivalent in age to large portions of the Imbrium basin surface (crater counts), most of the mare ridges in Sereni tatis experienced much 1ater growth and deforma- tion as demonstrated by their very sharp morphology and the un- usually large number of postmare craters filled by flows along the ridge flanks. 2) Despite the obvious 2-stage flooding of the basin there are few remnants of old flooded craters or ring structures, indicating either that the late stage filling was relatively deep or that some other deposit covered the surface before the most recent flooding. 3) The overturned strata in the rim flap of Bessel have exposed the bluish gray lavas found beneath the younger brownish gray surface rocks (1). The low depth/diameter ratio for Bessel (0.11) indicates that the con- tact zone must lie at a depth considerably shallower than the 1000 m depth of the crater floor below the surrounding surface.

  • Near Threatened Species NEAR THREATENED SPECIES
    Near Threatened species NEAR THREATENED SPECIES 2483 Threatened birds of Asia DWARF CASSOWARY Casuarius bennetti occurs in New Guinea (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea) and, presumably as a long-established introduction, on New Britain, where it is a forest species occurring into the mountains and occasionally to the treeline at 3,600 m (Coates 1985, Beehler et al. 1986). Although probably tolerant of moderate habitat degradation, logging opens up previously inaccessible areas to hunters; despite heavy hunting pressure, it remains relatively common over a wide altitudinal range (Coates 1985, Beehler et al. 1986, B. M. Beehler in litt. 2000, A. Mack in litt. 1999). It is judged to have a substantial population and to be declining more slowly than the other larger and more lowland cassowaries Casuarius.

  • Diamonds from the Ural Mountains: Their Characteristics and the Mineralogy and Geochemistry of Their Inclusions
    Diamonds from the Ural Mountains: their characteristics and the mineralogy and geochemistry of their inclusions Fernando A. T. P. Laiginhas, B.Sc. (Hons.) Thesis presented for the degree of Doctor of Philosophy (Ph.D.) University of Glasgow Department of Geographical and Earth Sciences December 2008 © Fernando A. T. P. Laiginhas, 2008 Abstract Abstract This thesis has investigated the geological origin of diamonds from the Ural Mountains. A set of inclusion-bearing diamonds from alluvial deposits in the western part of the Urals was characterised on the basis of their morphological features, nitrogen contents and nitrogen aggregation states, carbon and nitrogen stable isotopes, mineral inclusion geochemistry and radiometric isotopic ages of the inclusions. The vast majority of the studied diamonds are rounded dodecahedra, which indicates that the diamond population has experienced major resorption after crystallisation. The majority of the diamonds are affected by radiation damage and display evidence of transportation. Non-abraded diamonds exhibit similar surface features to those abraded, so they are probably of similar origin. The studied inclusion-bearing set of diamonds shares some characteristics with the overall, mostly inclusion-free, diamond population from the Ural Mountains. This similarity in physical characteristics strongly suggests that the Ural diamonds are all part of a single population. A Fourier Transform Infra-Red (FTIR) spectroscopy study allowed both the concentration of nitrogen and the aggregation states of this element to be quantified. Diamonds from other known primary deposits in the East European Craton (EEC) have FTIR signatures that do not match that of the studied population. Nitrogen thermometry results suggest that the Ural diamonds probably crystallised under similar pressure-temperature conditions.

    INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or “target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper lefi hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

  • Mantle Sulfides and Their Role in Re–Os and Pb Isotope Geochronology
    Reviews in Mineralogy & Geochemistry Vol. 81 pp. 579-649, 2016 10 Copyright © Mineralogical Society of America Mantle Sulfides and their Role in Re–Os and Pb Isotope Geochronology Jason Harvey Institute of Geophysics and Tectonics School of Earth and Environment University of Leeds Leeds, LS2 9JT United Kingdom Jessica M. Warren Geological and Environmental Sciences Stanford School of Earth Science Stanford University Stanford, CA 94305-2115 USA Steven B. Shirey Department of Terrestrial Magnetism Carnegie Institution of Washington Washington DC 20015-1305 USA INTRODUCTION Mantle sulfides (Fe–Ni–Cu-rich base metal sulfides or BMS; Fig. 1) play a crucial role in the distribution of Re, Os, and Pb in mantle rocks and are thus fundamental to obtaining absolute ages by direct geochronology using the Re–Os and Pb–Pb isotope systems on mantle samples. Mantle samples exist as hundreds of exposures of peridotites, pyroxenites and diamonds, either brought to the surface as accidental xenoliths and xenocrysts during kimberlitic or alkali basaltic volcanism (for comprehensive reviews, see Pearson et al. 2014; Aulbach et al. 2016, this volume; Luguet and Reisberg 2016, this volume), or as orogenic, ophiolitic and abyssal peridotite obducted at convergent margins and drilled / dredged from oceanic basins (e.g., Bodinier and Godard 2014; Becker and Dale 2016, this volume). This chapter reviews the occurrence of BMS in mantle samples and the role that they play in controlling the Re–Os and Pb isotope systematics of the mantle. Included in this review is a discussion of the role BMS plays in recording the multiple depletion / enrichment / metasomatic events that the mantle has undergone and the preservation of chemical heterogeneities that are inherently created by these processes.
