  • The Future of Continental Scientific Drilling U.S
    THE FUTURE OF CONTINENTAL SCIENTIFIC DRILLING U.S. PERSPECTIVE Proceedings of a workshop | June 4-5, 2009 | Denver, Colorado DOSECC WORKSHOP PUBLICATION 1 Front Cover: Basalts and rhyolites of the Snake River Plain at Twin Falls, Idaho. Project Hotspot will explore the interaction of the Yellowstone hotspot with the continental crust by sampling the volcanic rocks underlying the plain. Two 1.5 km holes will penetrate both the surficial basalt and the underlying rhyolite caldera-fill and outflow depos- its. A separate drill hole will explore the paleoclimate record in Pliocene Lake Idaho in the western Snake River Plain. In addition to the understanding of continent-mantle interaction that develops and the paleoclimate data collected, the project will study water-rock interaction, gases emanating from the deeper curst, and the geomicro- biology of the rocks of the plain. Once scientific objectives and set, budgets are developed, and funding is granted, successful implementation of projects requires careful planning, professional on-site staff, appropriate equip- ment, effective logistics, and accurate accounting.

Karot, gölün güneybatı bölümünden, 9 m su derinliğinden gravite karotiyer kullanılarak alınmıştır. 55 cm uzunluğundaki bu karottan alınan örneklerden elde edilen palinolojik verilere göre, göl çevresinde, çökelme süresince otsu bir paleoflora hakim olmuştur. Büyük oranda Poaceae familyasına ait polenlerin baskın olduğu gözlenmiştir. Elde edilen flora, günümüzdeki bitki örtüsü ile benzer olup çökelim süresince göl çevresinde step vejetasyonunun baskın olduğunu göstermektedir.

Preliminary Palynological Findings of theN3 Core from Southwest of Lake Nazik (Bitlis, Turkey) Abstract: This study includes preliminarily palynological findings of the N3 sedimentcore from Lake Nazik (Bitlis). The core was taken from 9 m water depth by using gravity corer from the southwestern side of Lake Nazik. According to palynological data from the samples of this core, 55 cm in length, herbaceous palaeoflora was been dominated during the deposition surroundings of the lake. The palaeoflora was mainly dominated by Poaceae pollen grains are similar to the recent flora and points out the dominance of steppe vegetation around the lake.

  • Terrestrial Impact Structures Provide the Only Ground Truth Against Which Computational and Experimental Results Can Be Com­ Pared
    Ann. Rev. Earth Planet. Sci. 1987. 15:245-70 Copyright([;; /987 by Annual Reviews Inc. All rights reserved TERRESTRIAL IMI!ACT STRUCTURES ··- Richard A. F. Grieve Geophysics Division, Geological Survey of Canada, Ottawa, Ontario KIA OY3, Canada INTRODUCTION Impact structures are the dominant landform on planets that have retained portions of their earliest crust. The present surface of the Earth, however, has comparatively few recognized impact structures. This is due to its relative youthfulness and the dynamic nature of the terrestrial geosphere, both of which serve to obscure and remove the impact record. Although not generally viewed as an important terrestrial (as opposed to planetary) geologic process, the role of impact in Earth evolution is now receiving mounting consideration. For example, large-scale impact events may hav~~ been responsible for such phenomena as the formation of the Earth's moon and certain mass extinctions in the biologic record. The importance of the terrestrial impact record is greater than the relatively small number of known structures would indicate. Impact is a highly transient, high-energy event. It is inherently difficult to study through experimentation because of the problem of scale. In addition, sophisticated finite-element code calculations of impact cratering are gen­ erally limited to relatively early-time phenomena as a result of high com­ putational costs. Terrestrial impact structures provide the only ground truth against which computational and experimental results can be com­ pared. These structures provide information on aspects of the third dimen­ sion, the pre- and postimpact distribution of target lithologies, and the nature of the lithologic and mineralogic changes produced by the passage of a shock wave.

  • Central Ring Structure Identified in One of the World's Best-Preserved Impact
    Central ring structure identi®ed in one of the world's best-preserved impact craters A.C. Gebhardt F. Niessen Alfred Wegener Institute for Polar and Marine Research, Columbusstraûe, 27568 Bremerhaven, Germany C. Kopsch Alfred Wegener Institute for Polar and Marine Research, Telegrafenberg A43, 14473 Potsdam, Germany ABSTRACT Seismic refraction and re¯ection data were acquired in 2000 and 2003 to study the morphology and sedimentary ®ll of the remote El'gygytgyn crater (Chukotka, northeast- ern Siberia; diameter 18 km). These data allow a ®rst insight into the deeper structure of this unique impact crater. Wide-angle data from sonobuoys reveal a ®ve-layer model: a water layer, two lacustrine sedimentary units that ®ll a bowl-shaped apparent crater mor- phology consisting of an upper layer of fallback breccia with P-wave velocities of ;3000 m/s, and a lower layer of brecciated bedrock (velocities .3600 m/s). The lowermost layer shows a distinct anticline structure that, by analogy with other terrestrial and lunar cra- ters of similar size, can be interpreted as a central ring structure. The El'gygytgyn crater exhibits a well-expressed morphology that is typical of craters formed in crystalline target rocks.

This is the first report of coesite from the Lonar crater. Coesite occurs within SiO2 glass as distinct ~30 lm spherical aggregates of “granular coesite” identifiable both with optical petrography and with micro-Raman spectroscopy. The coesite+glass occurs only within former silica amygdules, which is also the first report of high-pressure polymorphs forming from a shocked secondary mineral. Detailed petrography and NMR spectroscopy suggest that the coesite crystallized directly from a localized SiO2 melt, as the result of complex interactions between the shock wave and these vesicle fillings. INTRODUCTION Although there is no direct observation of nonshock stishovite in nature, a possible post-stishovite phase may High-Pressure SiO2 Phases be a large component of subducting slabs and the core- mantle boundary (Lakshtanov et al. 2007), and Silica (SiO2) polymorphs are some of the simplest stishovite likely occurs in the deep mantle if basaltic minerals in terms of elemental chemistry, yet they are slabs survive to depth.
