Based on kinetic isotope effect studies and product analysis, an ET-PT mechanism was proposed for the reaction of tryptophan substrate with N4Py ferryl and …


Grounding-Line Basal Melt Rates Determined Using Radar-Derived Internal Stratigraphy, Ginny Catania, Christina L. Hulbe, Howard Conway 2010 University of Texas at Austin

Grounding-Line Basal Melt Rates Determined Using Radar-Derived Internal Stratigraphy, Ginny Catania, Christina L. Hulbe, Howard Conway

Geology Faculty Publications and Presentations

We use ice-penetrating radar data across grounding lines of Siple Dome and Roosevelt Island, Antarctica, to measure the spatial pattern, magnitude and duration of sub-ice-shelf melting at these locations. Stratigraphic layers across the grounding line show, in places, a large-amplitude downwarp at, or slightly downstream of, the grounding line due to sub-ice-shelf basal melting. Localized downwarping indicates that melting is transient; melt rates, or the grounding line position, have changed within a few hundred years in order to produce the observed stratigraphy. Elsewhere, no meltrelated stratigraphic signature is preserved. In part, heterogeneity in the amount of sub-ice-shelf melt is due …


Propagation Of Long Fractures In The Ronne Ice Shelf Investigated Using A Numerical Model Of Fracture Propagation, Christina L. Hulbe, Christine Marie LeDoux, Kenneth M. Cruikshank 2010 Portland State University

Propagation Of Long Fractures In The Ronne Ice Shelf Investigated Using A Numerical Model Of Fracture Propagation, Christina L. Hulbe, Christine Marie Ledoux, Kenneth M. Cruikshank

Geology Faculty Publications and Presentations

Long rifts near the front of the Ronne Ice Shelf, Antarctica, are observed to begin as fractures along the lateral boundaries of outlet streams feeding the shelf. These flaws eventually become the planes along which tabular icebergs calve. The fractures propagate laterally as they advect through the shelf, with orientations that can be explained by the glaciological stress field. Fracture length remains constrained over much of the advective path, and locations of crack tip arrest are observed to coincide with structural boundaries, such as suture zones between ice from adjacent outlet glaciers. Geomechanical principles and numerical models demonstrate that in …


The Jets Of Tev Blazars At Higher Resolution: 43 Ghz And Polarimetric Vlba Observations From 2005-2009, B. Glenn Piner, Philip G. Edwards 2010 Whittier College

The Jets Of Tev Blazars At Higher Resolution: 43 Ghz And Polarimetric Vlba Observations From 2005-2009, B. Glenn Piner, Philip G. Edwards

Physics

We present 23 new VLBA images of the six established TeV blazars Markarian 421, Markarian 501, H 1426+428, 1ES 1959+650, PKS 2155-304, and 1ES 2344+514, obtained from 2005 to 2009. Most images were obtained at 43 GHz, and they reveal the parsec-scale structures of three of these sources (1ES 1959+650, PKS 2155-304, and 1ES 2344+514) at factors of two to three higher resolution than has previously been attained. Most of the remaining images map the linear polarization structures at a lower frequency of 22 GHz. We discuss the transverse structures of the jets as revealed by the high-frequency …

Basement Types, Lower Eocene Series, Upper Eocene Olistostromes And The Initiation Of The Southern Thrace Basin, Nw Turkey, Aral İ. Okay, Ercan Özcan, William Cavazza, Ni̇lgün Okay, György Less

Turkish Journal of Earth Sciences

The Eocene sequence of the southern Thrace Basin unconformably overlies two types of basement: (1) Slate, limestone and phyllite crop out in small inliers under the Upper Eocene conglomerates and limestones in the Mecidiye region, north of Saros Bay. These low-grade metamorphic rocks form the eastern extension of the Circum-Rhodope Belt of Greece. (2) In the Şarköy region south of the Ganos Fault, tectonically elevated basement consisting of serpentinite, metadiabase and Upper Cretaceous blueschists is unconformably overlain by the upper Bartonian to lower Priabonian shallow marine limestones of the Soğucak Formation. In some places erosional remnants of an upper Ypresian …


Mineral And Whole-Rock Geochemistry Of The Kestanbol Granitoid (Ezine-Çanakkale) And Its Mafic Microgranular Enclaves In Northwestern Anatolia: Evidence Of Felsic And Mafic Magma Interaction, SABAH YILMAZ ŞAHİN, YÜKSEL ÖRGÜN, YILDIRIM GÜNGÖR, A.

Mineral And Whole-Rock Geochemistry Of The Kestanbol Granitoid (Ezine-Çanakkale) And Its Mafic Microgranular Enclaves In Northwestern Anatolia: Evidence Of Felsic And Mafic Magma Interaction, Sabah Yilmaz Şahi̇n, Yüksel Örgün, Yildirim Güngör, A. Feti̇ Göker, A. Haydar Gülteki̇n, Zeki̇ye Karacik

Turkish Journal of Earth Sciences

The Miocene Kestanbol granitoid, in Ezine-Çanakkale, Turkey, is one of post-collision granitoids of western Anatolia, which have been related to the the late Cretaceous collision between the Anatolide-Tauride platform and the Pontides. Magmatism began during the early Miocene, with coeval alkaline to calc-alkaline plutonism and volcanism, controlled by the regional tectonic evolution. The Kestanbol pluton intruded regionally metamorphosed basement rocks. Volcanic and volcano-clastic sedimentary rocks overlie the pluton, which is bounded in the west and east by major faults. The pluton is frequently cut by felsic and mafic dykes and includes mafic microgranular enclaves (MMEs) that are mixing products of …

Statistical Evaluation Of Bivariate, Ternary And Discriminant Function Tectonomagmatic Discrimination Diagrams, Surendra P. Verma

Turkish Journal of Earth Sciences

This work applies a statistical methodology involving the calculation of success rates to evaluate a total of 28 tectonomagmatic discrimination diagrams: four bivariate (Ti/Y-Zr/Y; Zr-Zr/Y; Ti/1000-V; and Nb/Y-Ti/Y); six ternary (Zr-3Y-Ti/1000; MgO-Al2O3-FeOt, Th-Ta-Hf/3; 10MnO-15P2O5-TiO2; Zr/4-Y-2Nb; and La/10-Nb/8-Y/15); and three old (Score1-Score2; F1-F2; and F2-F3) and three sets of new discriminant function diagrams (each set consisting of five DF1-DF2 type diagrams proposed during 2004-2008). I established and used extensive geochemical databases of Miocene to Recent fresh rocks from island arcs, back arcs, continental rifts, ocean-islands, and mid-ocean ridges. Rock and magma types were inferred from a SINCLAS computer program. Although some …

Petrography And Geochemistry Of The Jajarm Bauxite Ore Deposit, Northeast Iran: Implications For Source Rock Material And Ore Genesis, Dariush Esmaeily, Hosein Rahimpour-Bonab, Amir Esna-Ashari, Ali Kananian

Turkish Journal of Earth Sciences

The Jajarm bauxite deposit, northeast Iran, is the largest such deposit in Iran. The deposit is sandwiched between the Triassic Elika formation and the Jurassic Shemshak formation, housed within karstic features developed within the former unit. The deposit generally shows an internal layering defined by the following four distinct horizons (from bottom to top): (a) a lower argillaceous horizon, approximately 50-80 cm thick, is mainly composed of clay minerals that directly overlies the carbonate footwall (Elika formation); (b) a bauxitic clay layer approximately 2-3 m thick that consists mainly of hematite, kaolinite, anatase, and diaspore; (c) a red bauxite layer …


Displacements And Kinematics Of The February 1, 1944 Gerede Earthquake (North Anatolian Fault System, Turkey): Geodetic And Geological Constraints, MEHMET EMİN AYHAN, ALİ KOÇYİĞİT 2010 TÜBİTAK

Displacements And Kinematics Of The February 1, 1944 Gerede Earthquake (North Anatolian Fault System, Turkey): Geodetic And Geological Constraints, Mehmet Emi̇n Ayhan, Ali̇ Koçyi̇ği̇t

Turkish Journal of Earth Sciences

The North Anatolian Fault System (NAFS) is an approximately 2-110-km-wide, 1600-km-long right-lateral intra-continental transform fault boundary between the Anatolian platelet and the Eurasian plate. The Gerede fault zone is one of the major active structures in the western section of the NAFS. It is a 1-9-km-wide, 325-km-long and ENE-trending dextral strike-slip fault zone, with a total accumulated offset since its initiation (Late Pliocene) of about 43 km. This offset indicates an average geological slip rate of 16.5 mm/yr. The 1 February 1944 Gerede earthquake occurred within the Gerede fault zone. Based on recent field geological mapping of the rupture traces …


Foraminiferal Biostratigraphy And Palaeoenvironmental Reconstruction Of The Paleocene–Eocene Transition At The Kharrouba Section, Tunisia (Southern Tethys Margin), LAMIA ZILI, DALILA ZAGHBIB-TURKI 2010 TÜBİTAK

Foraminiferal Biostratigraphy And Palaeoenvironmental Reconstruction Of The Paleocene–Eocene Transition At The Kharrouba Section, Tunisia (Southern Tethys Margin), Lamia Zili, Dalila Zaghbib-Turki

Turkish Journal of Earth Sciences

At Kharrouba (near Tunis City in northern Tunisia), on the southern margin of the Tethyan realm, the Paleocene-Eocene (P-E) transition interval deposition is continuous and complete. Based on high-resolution analysis and quantitative data of planktonic and benthic foraminifera at the Kharrouba section, this transition interval records expanded deposition of the relevant standard planktonic foraminiferal biozones with indicative index species i.e.: Morozovella velascoensis for the latest Paleocene P5 zone, and Acarinina sibaiyaensis for the earliest Eocene E1 zone, Pseudohastigerina wilcoxensis for the E2 zone, Morozovella marginodentata for the E3 zone and Morozovella formosa for the E4 zone. This complete section contains …


Geochronological Evidence Of Pan-African Eclogites From The Central Menderes Massif, Turkey, OBERHAENSLI ROLAND, OSMAN CANDAN, Franziska Wilke 2010 TÜBİTAK

Geochronological Evidence Of Pan-African Eclogites From The Central Menderes Massif, Turkey, Oberhaensli Roland, Osman Candan, Franziska Wilke

Turkish Journal of Earth Sciences

The Menderes Massif in western Anatolia documents a complex geodynamic history from Precambrian to recent. Eclogitic relics found in metagabbros in the Precambrian basement were dated by the U/Pb method. The zircon age data from granulitic (coronitic) and eclogitic metagabbros is consistent with geological constraints as well as relative and radiometric ages of the host granulitic gneisses and augen gneisses. A Pan-African intrusion age (540 Ma) of the metagabbros and a shortly later eclogite facies event (530 Ma) are inferred. This scenario fits with the geodynamic evolution deduced form the acidic country rocks of the eclogitic metagabbros. Direct links between …


Bala (Ankara) Earthquakes: Implications For Shallow Crustal Deformation In Central Anatolian Section Of The Anatolian Platelet (Turkey), ONUR TAN, MUSTAFA CENGİZ TAPIRDAMAZ, SEMİH ERGİNTAV, SEDAT İNAN, YILDIZ İRAVUL, RUHİ SAATÇILAR, BEKİR TÜZEL, ADİL TARANCIOĞLU, SALİH KARAKISA, RECAİ FEYİZ KARTAL, SAMİ ZÜNBÜL, KENAN YANIK, MEHMET KAPLAN, FUAT ŞAROĞLU, ALİ KOÇYİĞİT 2010 TÜBİTAK

Turkish Journal of Earth Sciences

Central Anatolia is quiet in terms of seismic activity, and rarely earthquakes up to magnitude 5.6 occur in the inner part of the Anatolian block or Anatolian platelet. Southeast of Ankara, the capital city of Turkey, two earthquake sequences with maximum magnitude of 5.6 occurred in 2005 and 2007. We discuss these shallow crustal deformation in the Anatolian platelet, in the light of seismological data from these earthquakes (M_L= 5.6) and their aftershocks. Following the earthquake of December 20, 2007 near Bala town, Ankara, we installed seven temporary stations in the first 24 hours to observe the aftershock activity and …

Oligocene History Of The Çardak - Dazkırı Subbasin (Denizli, Sw Turkey): Integrated Molluscan And Planktonic Foraminiferal Biostratigraphy, Yeşi̇m İslamoğlu, Aynur Hakyemez

Turkish Journal of Earth Sciences

The detailed analysis of molluscan and planktonic foraminiferal fauna in the Oligocene Çardak-Dazkırı sub-basin, in northeastern Denizli provin ce (western Turkey) allowed accurate dating of the deposits, together with interpretation of their depositional environments. Gastropod, bivalve, scaphopod and planktonic foraminiferal assemblages identified in ten sections reveal a succession which was deposited between the Late Rupelian and Early Chattian. Planktonic foraminifera, documented for the first time in the basin, indicate the P19 Zone (Turborotalia ampliapertura Zone) of the Late Rupelian at the base of the succession whereas Molluscan fauna, determined for the first time in this study, assign the whole succession, …


Mathesia Mainelli (Hippuritoidea, Monopleuridae) From The Late Aptian−Albian Of The Mediterranean Region: A Revision, JEAN-PIERRE MASSE, MÜKERREM FENERCİ-MASSE 2010 TÜBİTAK

Mathesia Mainelli (Hippuritoidea, Monopleuridae) From The Late Aptian−Albian Of The Mediterranean Region: A Revision, Jean-Pierre Masse, Mükerrem Fenerci̇-Masse

Turkish Journal of Earth Sciences

Agria darderi Astre and Mathesia terticolloquiirudistarum Mainelli represent a single taxonomic entity: Mathesia darderi (Astre). Mathesia is characterized by an erect posterior myophoral plate and an anterior myophoral crest in the LV, the RV myophores being on the shell wall. A peculiar shell structure is observed in the RV: the junction between the outer calcitic shell layer and the inner formerly aragonitic shell layer is scalloped or festooned and usually includes longitudinal tubes. The overall morphological traits and myocardinal organisation of Mathesia are similar to those of Debrunia, although the latter lacks the scalloped or tubular inner shell features of …


A New Species Of Polyconites From The Lower Aptian Of Iberia And The Early Evolution Of Polyconitid Rudists, PETER W. SKELTON, EULÀLIA GILI, TELM BOVER-ARNAL, RAMON SALAS, JOSEP ANTON MORENO-BEDMAR 2010 TÜBİTAK

A New Species Of Polyconites From The Lower Aptian Of Iberia And The Early Evolution Of Polyconitid Rudists, Peter W. Skelton, Eulàlia Gili, Telm Bover-Arnal, Ramon Salas, Josep Anton Moreno-Bedmar

Turkish Journal of Earth Sciences

The main diagnostic character of polyconitid rudists is a distinctive ectomyophoral cavity inserted behind a reflexed posterior myophoral plate in the left valve. The only pre-Aptian Old World polyconitid taxon recognized in the current literature is Horiopleura dumortieri (Matheron): this species clearly shows the prominent posterior myophoral shelf in the right valve that is diagnostic of the genus, which continues into the Albian. Polyconites, by contrast, has a more depressed (operculiform) left valve and its posterior adductor was inserted on an inward-sloping swelling on the right valve inner wall, with no projecting shelf. Hitherto, the earliest known species of Polyconites …


Debrunia Occitanica Nov. Sp. (Monopleuridae) From The Early Aptian Of Se France, MÜKERREM FENERCİ-MASSE, JEAN-PIERRE MASSE 2010 TÜBİTAK

Debrunia Occitanica Nov. Sp. (Monopleuridae) From The Early Aptian Of Se France, Mükerrem Fenerci̇-Masse, Jean-Pierre Masse

Turkish Journal of Earth Sciences

Debrunia occitanica nov. sp., described from the early Aptian platform limestones of SE France, is characterized by: a moderately convex left valve, inconspicuous radial bands and a ligament groove in a depression flanked by two longitudinal rounded edges. Debrunia occitanica nov. sp. is considered as a chronospecies belonging to a single lineage rooted in the Barremian, and including Debrunia bruni and Debrunia mutabilis. Evolutionary trends in the three species include flattening of the left valve, development of the corresponding myophores, and reduction of the radial bands. This new species has the potential to be a stratigraphic marker for the early …


Dictyoptychus Douvillé: Taxonomic Revision, Phylogeny And Biogeography, SACİT ÖZER 2010 TÜBİTAK

Dictyoptychus Douvillé: Taxonomic Revision, Phylogeny And Biogeography, Saci̇t Özer

Turkish Journal of Earth Sciences

The late Campanian-Maastrichtian transgressive sequences of the southeastern Anatolia (northernmost part of the Arabian platform) and only one Maastrichtian limestone block within the ophiolitic association of the easternmost part of the Taurus Orogenic Belt contain very well-preserved specimens of Dictyoptychus Douvillé 1905. Study of Turkish specimens and also of those described in the literature reveals considerable ontogenic variability, hence need for revision of the species of the genus erected hitherto. Dictyoptychus leesi (Kühn 1929), Dictyoptychus paronai (Kühn 1929), Dictyoptychus persicus (Cox 1934), Dictyoptychus euphratica Karacabey-Öztemür 1979 and Dictyoptychus orontica Karacabey-Öztemür 1979 are accordingly re-interpreted to represent a single species synonymous …


Late Campanian Rudist Assemblages And Biometrical Analysis Of Pseudopolyconites From Bačevica (Eastern Serbia), TUNIS GIORGIO, TARLAO ALCEO, RADOICIC RAJKA 2010 TÜBİTAK

Late Campanian Rudist Assemblages And Biometrical Analysis Of Pseudopolyconites From Bačevica (Eastern Serbia), Tunis Giorgio, Tarlao Alceo, Radoicic Rajka

Turkish Journal of Earth Sciences

The lithological and faunal succession cropping out close to the famous palaeontological locality of Bacevica (Eastern Serbia) is described along a very discontinuous and ill-exposed section. Since the section is dominated by clastic sediments, no-vestige of the so-called 'Vrbovac reef' has been observed. Rhythms consisting of a limestone breccia lower unit and a fossil-rich upper part characterize the base of the section while rare silt and sand-rich limestone breccias and prevailing silty/sandy soils are the lithologies observed in the upper part of the same. The faunal succession shows an alternation of monospecific-paucispecific assemblages and much more diverse assemblages of rudists. …

Maastrichtian Rudist Fauna From Tarbur Formation (Zagros Region, Sw Iran): Preliminary Observations, Ahmad Reza Khazaei, Peter W. Skelton, Mehdi Yazdi̇

Turkish Journal of Earth Sciences

The uppermost Cretaceous Tarbur Formation of the Zagros region (SW Iran) is mainly siliciclastic in composition, though it also incorporates some carbonate units including several rudist lithosomes. Two sections through this formation, in the Semirom and Gerdbisheh areas, have been chosen for study of the lithosomes and their rudist fauna. These lithosomes vary in faunal content, geometry and internal organization (density and diversity). Preliminary investigation of the specimens collected from the studied sections reveals a diverse rudist fauna. Eleven genera and 23 species have been determined, belonging to the rudist families Hippuritidae, Radiolitidae and Dictyoptychidae. These rudist assemblages indicate a …
