Stratigraphy, facies and geodynamic settings of Jurassic formations in the Bükk Mountains, North Hungary: its relations with the other areas of the Neotethyan realm.

Jurassic mélange complexes related to the subduction of the Neotethys Ocean occur in the Bükk Mountains, North Hungary. This paper characterizes the sedimentary sequence of basin and slope facies that occur in the southwestern part of the Bükk Mountains, placing special emphasis on the redeposited sedimentary rocks (olistostromes, olistoliths: Mónosbél Group) in order to obtain information on the provenance of the clasts, and the mode and time of their redeposition. The series of formations studied shows a general coarsening-upwards trend. Based on radiolarians and foraminifera, the Mónosbél Group formed in Early to Late Bathonian time. The lower part of the complex is typified by a predominance of pelagic carbonates, shale and radiolarite with andesitic volcaniclastic intercalations. The higher part of the succession is characterized by polymictic olistostromes. Large olistoliths that are predominantly blocks of Bathonian shallow marine limestone (Bükkzsérc Limestone) appear in the upper part of the sequence. Based on the biostratigraphic and sedimentological data, results of analyses of the redeposited clasts and taking into consideration the concepts of the development of the western Neotethys domain, the evolutionary stages of the sedimentary basins were defined. The onset of the compressional stage led to initiation of nappe stacking that led to the formation of polymict olistostromes and then to the redeposition of large blocks derived from out-of-sequence nappes of the former platform foreland

Palaeotethyan, Neotethyan and Huglu-Pindos series in the Lycian Nappes (SW Turkey): geodynamical implications

The idea of a continuum between the Hellenides and the Taurides is based on correlations between the platform series of the external parts of the Hellenides-Taurides system, as well as similarities between sedimentary sequences in southwestern Turkey and in the Dodecanese islands (Greece). In this system, the Lycian Nappes, and particularly the Tavas Nappe occupy a key area. The Tavas Nappe forms the lowermost unit in the Lycian pile and is classically divided into the Karada , Teke Dere, Köyce iz and Haticeana units. The lowermost Karada unit consists of a Gondwana-type platform succession ranging from the Late Devonian to the Late Triassic. A large hiatus exists between the Sakmarian and the Middle Triassic (deposition of sandstones, quartzites and limestones). The Carnian is marked by a general deepening of the platform prior to the deposition of a wildflysch-like formation. The discovery of the Cordevolian (early Carnian) Pseudofurnishius murcianus murcianus conodonts fauna on top of the platform is of crucial importance. This fauna characterizes the Westmediterran-Arabian Province and is a typical indicator for the Neotethyan domain. The Karada unit is always found structurally below the Teke Dere unit, this superposition being a possible result of the Late Triassic Eocimmerian orogenic event. The Teke Dere unit is formed by several slices including Kasimovian OIB-type basalts representing a Palaeotethyan seamount, Carboniferous MORB-type basalts, an Early Carboniferous wildflysch-like siliciclastic deep-water series and a Middle Permian arc sequence. Both the platform limestones associated to the seamount and the dolostones above the Early Carboniferous siliciclastic series yield shallow-marine microfauna and microflora sharing strong biogeographical affinities with the northern Palaeotethyan borders. The thick Mesozoic sequence formed by the Köyce iz and Haticeana series occupies a high structural position above the Karadag and Teke Dere units. The base of the series comprises a Late Triassic continental formation followed by Liassic shallow-marine limestones and a late Liassic Ammonitico Rosso. It continues with late Liassic to Maastrichtian pelagic limestones and calciturbidites. A Late Palaeocene to Lutetian flysch unconformably overlies it. Locally, volcanic rocks associated with Late Triassic pelagic limestones, turbiditic sandstones, and calcareous sandstones alternating with volcaniclastic sediments form the lowermost exposure of the Köyce iz series. Detailed fieldwork supported by numerous micropalaeontological evaluations suggest that the Tavas Nappe is in reality highly composite and includes dismembered units belonging to the Palaeotethyan, Neotethyan and Huglu-Pindos realms. The Karada unit belongs to the Cimmerian Taurus terrane and was part of the northern passive margin of the Neotethys (= East-Mediterranean); the Teke Dere succession is composed of several thrust sheets of Palaeotethyan origin. Palaeotethyan remnants found as subduction-accretionary complexes or reworked during the Eocimmerian orogenic event provide a strong means to identify and locate the Palaeotethyan suture zone; the sedimentological evolution of the Köyce iz and Haticeana series is in many points similar to classical Pindos sequences. These series originated in the Hu lu-Pindos Ocean along the northern passive margin of the Anatolian (Turkey) and Sitia-Pindos (Greece) terranes

Overview of the Antarctic Circumnavigation Expedition : Study of Preindustrial-like Aerosols and Their Climate Effects (ACE-SPACE)

Uncertainty in radiative forcing caused by aerosol-cloud interactions is about twice as large as for CO2 and remains the least well understood anthropogenic contribution to climate change. A major cause of uncertainty is the poorly quantified state of aerosols in the pristine preindustrial atmosphere, which defines the baseline against which anthropogenic effects are calculated. The Southern Ocean is one of the few remaining near-pristine aerosol environments on Earth, but there are very few measurements to help evaluate models. The Antarctic Circumnavigation Expedition: Study of Preindustrial-like Aerosols and their Climate Effects (ACE-SPACE) took place between December 2016 and March 2017 and covered the entire Southern Ocean region (Indian, Pacific, and Atlantic Oceans; length of ship track >33,000 km) including previously unexplored areas. In situ measurements covered aerosol characteristics [e.g., chemical composition, size distributions, and cloud condensation nuclei (CCN) number concentrations], trace gases, and meteorological variables. Remote sensing observations of cloud properties, the physical and microbial ocean state, and back trajectory analyses are used to interpret the in situ data. The contribution of sea spray to CCN in the westerly wind belt can be larger than 50%. The abundance of methanesulfonic acid indicates local and regional microbial influence on CCN abundance in Antarctic coastal waters and in the open ocean. We use the in situ data to evaluate simulated CCN concentrations from a global aerosol model. The extensive, available ACE-SPACE dataset () provides an unprecedented opportunity to evaluate models and to reduce the uncertainty in radiative forcing associated with the natural processes of aerosol emission, formation, transport, and processing occurring over the pristine Southern Ocean.Peer reviewe

A Critique and Reframing of Personality in Labour Market Theory: Locus of Control and Labour Market Outcomes

This article critically examines the theoretical arguments that underlie the literature linking personality traits to economic outcomes and provides empirical evidence indicating that labour market outcomes influence personality outcomes. Based on data from the German Socio-Economic Panel, we investigated the extent to which gender differences occur in the processes by which highly positive and negative labour market outcomes are determined and in the processes underlying the development of one particular aspect of personality, locus of control. Gender differences were more pronounced in the results for years in managerial/ leadership positions than for locus of control. Negative labour market states were also marked by gender differences. We conclude by arguing that an explicitly value-laden analysis of the rewards associated with personality within the labour market could expose areas where the gendered nature of rewards by personality serves to perpetuate power relationships within the labour market
