Biostratigraphy and paleobiogeographic affinities of the Jurassic brachiopod assemblages from Sierra Espuña (Maláguide Complex, Internal Betic Zones, Spain)

The assemblages of Early Jurassic brachiopods (Pliensbachian - Toarcian) from Sierra Espuña (Murcia Province, SE Spain) are described. This is the only area in the Internal Zones of the Betic Cordillera, corresponding to the margins of the Alborán Terrane, where Jurassic brachiopods are known to occur. In the tectonic Unit of Morrón de Totana (more southward located) assemblage MT1 of Late Pliensbachian age has been characterized. This assemblage has been subdivided into three successive sub-assemblages: MT1a (Algovianum Zone), MT1b (Emaciatum Zone, Solare Subzone) and MT1c (Emaciatum Zone, Elisa Subzone). Northward, in the Perona tectonic Unit two distinct assemblages, P1 (Latest Sinemurian - Early Pliensbachian) and P2 (Early Toarcian, Serpentinum Zone) have been recognized. Differences between the assemblages from the two tectonic units are evident after the paleobiogeographical analysis. In the Morrón de Totana Unit, taxa with Mediterranean affinities occur. MT1 assemblage is very similar to assemblages previously known in the Eastern Subbetic as well as in other areas of the Mediterranean Province. In the Perona Unit the Mediterranean affinity of the assemblages is not so evident. P1 Assemblage consists of widely distributed taxa, lacking in the most characteristic elements of the Mediterranean Province which, however, are present in neighbouring Betic areas. P2 Assemblage belongs to the Spanish Province that develops in Western Tethys after the Early Toarcian Mass Extinction Event. The occurrence in this assemblage of Prionorhynchia aff. msougari Rousselle, until now only found in North Africa, indicates a closer connection of the Perona Unit with the African paleomargin of the Tethys than with the South Iberian paleomargin. The paleobiogeographical data suggest a more southern and marginal (close to epicontinental areas) position of the Perona Unit than the Morrón de Totana Unit.

Una nueva rábita en la playa de Guardamar del Segura: la rábita de El Moncayo

Se publican las noticias que ha arrojado la excavación en 2004 de unos muros situados en la denominada playa de El Moncayo. Los hallazgos se sitúan a unos 3 kilómetros al Sur del casco urbano de Guardamar del Segura; a unos 135 m. en dirección Norte está la Torre del Descargador (torre almenara de los siglos IV/X y V/XI), a unos 3,5 kilómetros se localiza El Castillo de Guardamar (de los siglos VIII a.C. al XIX) y, un poco más al Norte, a unos 4 kilómetros, en las proximidades de la desembocadura del Segura, los oratorios o rábitas de las dunas de Guardamar. Se dan a conocer los restos arquitectónicos y cerámicos aparecidos en la excavación del 2004 que se interpretan como de restos del recinto de una rábita o mezquitilla (cuando se excave más se verá si está aislada o hay más edificios similares), se presentan unos apuntes al hilo de la orientación de la rábita de El Moncayo y un estudio de la moneda andalusí hallada en la excavación de El Moncayo (datables entre en 429/1037-8 y 433/1041-2).

AMS C-14 ages of coretops collected on RRS Charles Darwin cruise CD159, July 2004, N. Atlantic, for the NERC RAPID programme

Material and data were collected at 41 sites in the subpolar North Atlantic Ocean between Scotland and Newfoundland, during the RRS CharlesDarwin CD159 cruise in July 2004 (McCave, 2005). Sites were selected to reflect the major inputs of water that becomes the North Atlantic Deep Water (NADW); the Iceland-Scotland Overflow Water (ISOW), the Denmark Strait Overflow Water (DSOW) and the Labrador Sea Water (LSW). Areas cored were the south Iceland Rise, SE Greenland slope/rise and Eirik Drift, and the Labrador margin. A total of 29 box cores, 19 piston cores, 6 kasten cores, 9 short gravity cores and 20 CTD casts as well as 28 surface water samples were collected during the cruise. Here we present sediment core-top sample ages. The cores were sampled at 1 or 0.5 cm intervals and we used the top 1 or 2 cm, depending on availability of foraminifera in the samples. Sediment samples were disaggregated on an end-over-end wheel, wet sieved at >63 um, and dry sieved to 63-150 and >150 um. Accelerator Mass Spectrometer (AMS) radiocarbon dating was done for each core top based on between 900-1600 monospecific planktonic foraminifera (Globigerina bulloides or Neogloboquadrina pachyderma (sinistral)). All dates were of modern or late Holocene age except site RAPID-08-5B (9806 ± 38 uncorrected 14C years BP) and site RAPID-14-10B (11543 ± 40 uncorrected 14C years BP). The >150 um fraction was split until approximately 300 foraminifera remained and counted for number of lithic grains, benthic foraminifera, planktonic foraminifera and foraminifera fragments. In all but the shallowest sample (Greenland rise, 761m water depth) benthic foraminifera constituted less than 2% of the total >150 um fraction of the sample.

Distribution of late Turronian planktonic foraminifers in ODP Hole 114-700B

The oldest Cretaceous sediments in the subantarctic region were recovered from ODP Hole 700B in the East Georgia Basin. Planktonic foraminifers from the deepest indurated limestones could be attributed to the Marginotruncana schneegansi Zone of late Turonian age.

Shoemaker impact structure, Western Australia

The Shoemaker impact structure, on the southern margin of the Palaeoproterozoic Earaheedy Basin, with an outer diameter of similar to30 km, consists of two well-defined concentric ring structures surrounding a granitoid basement uplift. The concentric structures, including a ring syncline and a ring anticline, formed in sedimentary rocks of the Earaheedy Group. In addition, aeromagnetic and geological field observations suggest that Shoemaker is a deeply eroded structure. The central 12 km-diameter uplift consists of fractured Archaean basement granitoids of syenitic composition (Teague Granite). Shock-metamorphic features include shatter cones in sedimentary rocks and planar deformation features in quartz crystals of the Teague Granite. Universal-stage analysis of 51 sets of planar deformation features in 18 quartz grains indicate dominance of sets parallel to omega (10 (1) over bar3}, but absence of sets parallel to pi (10 (1) over bar2}, implying peak shock pressures in the range of 10-20 GPa for the analysed sample. Geophysical characteristics of the structure include a -100 mus(-2) gravity anomaly coincident with the central uplift and positive circular trends in both magnetic and gravity correlating with the inner ring syncline and outer ring anticline. The Teague Granite is dominated by albite-quartz-K-feldspar with subordinate amounts of alkali pyroxene. The alkali-rich syenitic composition suggests it could either represent a member of the Late Archaean plutonic suite or the product of alkali metasomatism related to impact-generated hydrothermal activity. In places, the Teague Granite exhibits partial to pervasive silicification and contains hydrothermal minerals, including amphibole, garnet, sericite and prehnite. Recent isotopic age studies of the Teague Granite suggest an older age limit of ca 1300 Ma (Ar-Ar on K-feldspar) and a younger age limit of ca 568 Ma (K-Ar on illite-smectite). The significance of the K-Ar age of 568 Ma is not clear, and it might represent either hydrothermal activity triggered by impact-related energy or a possible resetting by tectonothermal events in the region.

Pleistocene occupation of New Guinea's highland and subalpine environments

New Guinea's mountains provide an important case study for understanding early modern human environmental adaptability and early developments leading to agriculture. Evidence is presented showing that human colonization pre-dated 35ka (ka = thousands of uncalibrated radiocarbon years before present) and was accompanied by landscape modification using fire. Sorties into the subalpine zone may have occurred before the Late Glacial Maximum (LGM), and perhaps contributed to megafaunal extinction. Humans persisted in the intermontane valleys through the LGM and expanded rapidly into the subalpine on climatic warming, when burning and clearance may have retarded vegetation re-colonization. Plant food use dates from at least 31ka, confirming that some of New Guinea's distinctive agricultural practices date to the earliest millennia of human presence.

A estela de MESA: uma introdução à arqueologia e à literatura de Moab

Essa dissertação faz uma introdução aos aspectos arqueológicos e literários de Moab, temática carente de publicações em língua portuguesa. Trata, primeiramente, dos fatos relacionados à descoberta da inscrição de Mesa na segunda metade do século 19, das disputas diplomáticas que ocasionaram a destruição da inscrição, bem como das obras científicas que, durante as décadas seguintes, abordaram o assunto. Na seqüência, apresenta as principais características geográficas e arqueológicas de Moab, durante as Idades do Bronze Recente, do Ferro Antigo e do Ferro Recente, dando especial atenção aos assentamentos humanos, mas também às grandes construções e às esculturas, consideradas recursos culturais necessários ao estado moabita, patrimonial e segmentário, que fazia uso de metáforas domésticas para referendar sua hegemonia; além do mais, apresenta o lugar de Moab no mundo assírio, e sua importância como rota comercial. A tradução da estela de Mesa, os comentários filológicos e a análise da sua forma e do seu gênero literário, apontam para um texto elaborado a partir de ferramentas literárias claras, utilizado para marcar o poder da monarquia moabita. Tais aspectos arqueológicos e literários sustentam que o desenvolvimento de Moab ocorreu após o fim da dominação do Israel omrida, além de sugerirem um novo olhar sobre a Bíblia Hebraica.(AU)

Factors affecting the accommodative response to sustained visual tasks

In the absence of adequate visual stimulation accommodation adopts an intermediate resting position, appropriately termed tonic accommodation (TA). A period of sustained fixation can modify the tonic resting position, and indicate the adaptation properties of TA. This thesis investigates various factors contributing to the accommodative response during sustained visual tasks, in particular the adaptation of TA. Objective infra-red optometry was chosen as the most effective method of measurement of accommodation. This technique was compared with other methods of measuring TA and the results found to be well correlated. The inhibitory sympathetic input to the ciliary muscle provides the facility to attenuate the magnitude and duration of adaptive changes in TA. This facility is, however, restricted to those individuals having relatively high levels of pre-task TA. Furthermore, the facility is augmented by substantial levels of concurrent parasympathetic activity. The imposition of mental effort can induce concurrent changes in TA which are predominantly positive and largely the result of an increase in parasympathetic innervation of the ciliary muscle although there is some evidence for sympathetic attentuation at higher levels of TA. In emmetropes sympathetic inhibition can modify the effect of mental effort on the steady-state accommodative response at near. Late-onset myopes (onset after the age of 15 years) have significantlylower values of TA then emmetropes. Similarly, late-onset myopes show lower values of steady-state accommodative response for nearstimuli. The imposition of mental effort induces concurrent increases in TA and steady-state accommodative response in the myopic group which are significantly greater than those for emmetropes. Estimates of TA made under bright empty-field conditions are well correlated with those made under darkroom conditions. The method by which the accommodative loop is opened has no significant effect on the magnitude and duration of post-task shifts in TA induced by a near vision task. Significant differences in the post-task shifts in TA induced by a near vision task exist between emmetropes and late-onset myopes, the post-task shifts being more sustained for the myopic group.

Turkish-American relations in the post-Cold War era, 1990-2005

This study examines the contours of Turkish-American foreign relations in the post-Cold War era from 1990 to 2005. While providing an interpretive analysis, the study highlights elements of continuity and change and of convergence and divergence in the relationship between Ankara and Washington. Turkey’s encounter with its Kurdish problem at home intertwined with the emergence of an autonomous Kurdish authority in northern Iraq after the Gulf War that left a political vacuum in the region. The main argument of this dissertation is that the Kurdish question has been the central element in shaping and redefining the nature and scope of Turkish-American relations since 1991. This study finds that systemic factors primarily prevail in the early years of the post-Cold War Turkish-American relations, as had been the case during the Cold War era. However, the Turkish parliament’s rejection of the deployment of the U.S. troops in Turkey for the invasion of Iraq in 2003 could not be explained by the primacy of distribution of capabilities in the system. Instead, the role of identity, ideology, norms, and the socialization of agency through interaction and language must be considered. The Justice and Development Party’s ascension to power in 2002 magnified a wider transformation in domestic and foreign politics and reflected changes in Turkey’s own self-perception and the definition of its core interests towards the United States.

Isotope measurements from ODP Hole 104-642B

The Pliocene (5.3-2.6 Ma) is often described as a relatively stable climatic period, with warm temperatures characterizing high latitudes. New suborbital resolved stable isotope records from ODP Hole 642B in the Eastern Nordic Seas document that the Pliocene was not a stable period characterized by one climate. Rather, seven distinct climate phases, each lasting between 150,000 and 400,000 years, are identified and characterized in the time interval 5.1-3.1 Ma. Four of the transitions between the defined climate phases occurred close to an eccentricity minimum and a minimum in amplitude of change for Northern Hemisphere summer insolation, while two occurred around an eccentricity maximum and a maximum in amplitude in insolation change. Hence, a low frequency response of the Nordic Seas to insolation forcing is indicated. In addition, paleogeographic and related paleoceanographic changes, expansion of the Arctic sea ice cover and onset of NHG were important factors behind the evolving Pliocene low frequency variability in the eastern Nordic Seas. It is likely that the identified climate phases and transitions are important beyond the Nordic Seas, due to their association with changes to both insolation and paleogeography. Also, a strong and variable degree of diagenetic calcite overgrowth is documented for the planktic foraminifera, especially influencing the planktic d18O results; the absolute values and amplitude of change cannot be taken at face value.
