Clonal Propagation Of Dorystoechas Hastata Via Axillary Shoot Proliferation, Bengi̇ Erdağ, Yelda Emek, Serap Aydoğan
Turkish Journal of Botany
A protocol for the in vitro seed germination, seedling development, and axillary shoot propagation of Dorystoechas hastata Boiss. & Heldr. ex Bentham is described. By employing sterilised seeds that were transferred onto in vitro media, the effects of various in vitro media, photoperiods, and temperatures on germination were investigated. At the end of these experiments, a final protocol was determined for the in vitro germination of D. hastata seeds. With this protocol, the highest germination rate was obtained with distilled water supplemented with vitamins and 1 mg L^{-1} of gibberellic acid (GA_{3}), with a 16:8 photoperiod at 24 ± 2 …
Numerical Ages Of Selected Rudist Bivalvia: Preliminary Results, Robert W. Scott
Numerical Ages Of Selected Rudist Bivalvia: Preliminary Results, Robert W. Scott
Turkish Journal of Earth Sciences
The ranges of most biostratigraphically diagnostic fossils have been calibrated to the geologic time scale in mega-annums. Five methods for integrating fossil ranges with the numerical geologic time scale are currently used: (1) species in stratigraphic positions with radiometrically dated beds; (2) strontium isotopes of unaltered shell material; (3) cyclostratigraphic frequencies of enclosing strata; (4) integration with zones and sequence stratigraphy; and (5) graphic correlation. Preliminary studies show that rudist occurrences have been calibrated in numerical ages by Sr isotopes, zonal integration and graphic correlation. Where the same species are dated by two methods, a more complete range is the …

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 …
Statistical Evaluation Of Classification Diagrams For Altered Igneous Rocks, Surendra P. Verma, Rodolfo Rodriguez Rios, Rosalinda González-Ramírez
Statistical Evaluation Of Classification Diagrams For Altered Igneous Rocks, Surendra P. Verma, Rodolfo Rodriguez Rios, Rosalinda González-Ramírez
Turkish Journal of Earth Sciences
The International Union of Geological Sciences (IUGS) has proposed recommendations for the classification of relatively fresh volcanic rocks, but with no specific instructions for altered volcanic rocks, other than discouraging the use of the total alkalis versus silica diagram. The Nb/Y-Zr/TiO2 diagram has been in use for the classification of altered rocks now for over 30 years. Recently (during 2007) another diagram (Co-Th) has been proposed to replace this old diagram, particularly for altered arc rocks. Using an extensive database of all kinds of relatively fresh rocks from four tectonic settings (island arc, continental rift, ocean island, and mid-ocean ridge), …
Testing Miocene Remagnetization Of Bey Dağları: Timing And Amount Of Neogene Rotations In Sw Turkey, Douwe J.J. Van Hinsbergen, Mark J. Dekkers, Ayten Koç
Testing Miocene Remagnetization Of Bey Dağları: Timing And Amount Of Neogene Rotations In Sw Turkey, Douwe J.J. Van Hinsbergen, Mark J. Dekkers, Ayten Koç
Turkish Journal of Earth Sciences
Here we reassess the timing and amount of rotation of the eastern limb of the Aegean orocline, located in SW Turkey. The current model for this orocline involves a 25-30° counterclockwise (CCW) rotation of the Bey Dağları region, which exposes upper Cretaceous to Eocene platform carbonates and lower Miocene flysch deposits. In this model the rotation has to postdate a Miocene remagnetization, which would not exclude non-synchroneity between rotations of the western and eastern limbs of the Aegean orocline. To test this model a detailed palaeomagnetic study was conducted on lower Miocene strata in the Bey Dağları area. Two (composite) …

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 …
Sensitivity Analysis On Relations Between Earthquake Source Rupture Parameters And Far-Field Tsunami Waves: Case Studies In The Eastern Mediterranean Region, Seda Yolsal, Tuncay Taymaz
Sensitivity Analysis On Relations Between Earthquake Source Rupture Parameters And Far-Field Tsunami Waves: Case Studies In The Eastern Mediterranean Region, Seda Yolsal, Tuncay Taymaz
Turkish Journal of Earth Sciences
We present several sensitivity tests, that were applied to exhibit the effects of earthquake source rupture characteristics on amplitudes, frequency contents and arrival times of earthquake generated tsunami waves in the far field, as case studies in the eastern Mediterranean. The investigated earthquake parameters are principally epicentral location, focal mechanism parameters (strike, dip and rake angles), faulting area dimensions, maximum displacement and focal (centroid) depth. We have implemented a numerical method of TUNAMI-N2 based on non-linear shallow-water theory to obtain synthetic water surface fluctuations at selected pseudo tide gauge locations in the eastern Mediterranean. It has been observed that the …
Tsunami Hazard Assessment On The Southern Coast Of Spain, Mauricio González, Raul Medina, Maitane Olabarrieta, Luis Otero
Tsunami Hazard Assessment On The Southern Coast Of Spain, Mauricio González, Raul Medina, Maitane Olabarrieta, Luis Otero
Turkish Journal of Earth Sciences
In this study an indirect statistical method has been proposed to estimate the tsunami hazard assessment along the Alborán Sea Coast (Southeastern Spanish Coast). This method can be summarized as: (1) analysis of the global neotectonic setting, including geodynamic processes as well as seismicity of the region; (2) tsunami source model; (3) generation of a numerical data base of tsunami events using a numerical model; (4) probabilistic model based on Monte-Carlo simulations in order to generate a synthetic tsunami catalogue; and (5) a multidimensional interpolation method applied to combine the numerical data base with the synthetic catalogue to produce inundation …
Geochronological Evidence Of Pan-African Eclogites From The Central Menderes Massif, Turkey, Oberhaensli Roland, Osman Candan, Franziska Wilke
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 …

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, …

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 …

Blending Rudists With Technology; Non-Destructive Examination Of The Internal And External Structures Of Rudists Using High Quality Scanning And Digital Imagery, Ann Molineux, Robert W. Scott, Jessie Maisano, Richard Ketcham, Louis Zachos
Turkish Journal of Earth Sciences
Certain formations within the Cretaceous of Texas include zones of silicified rudists. Such diagenetic alteration, combined with the timing of alteration, has preserved many structural features of the rudist suitable for computed tomography (CT scanning). The excellent density differences between those skeletal structures (silica) and the internal sediment (calcitic mud) or later crystallization (calcite), fulfill a fundamental requirement for such analysis. The Jackson School of Geosciences at The University of Texas provides access to a high resolution computed tomography scanning system. This equipment, not identical to medical scanners, provides higher resolution and sophisticated software to analyze the imagery. Several rudist …

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 …
