Le politique via la lexicologie: la revue Mots
No full textIn this article we try to reconstruct the genesis of the revue Mots. Les langages du politique: founded at the beginning of the 80, this revue is nowadays the most known scientific revue for lexicological and political studies at the time concerning french language. Its origins date back to the 60, within the “Laboratoire d’étude des textes politiques” of the ENS of Saint-Cloud, and around the debate which led to the birth of modern lexicology. We will try, on the one hand, to reconstruct the ‘theoretical’ context from which the revue spread out and propose, on the other hand, its evolution, both from formal and thematic points of view
Metamorphic evolution of the Saka Unit (Central Pontides, Northern Turkey): new implications for the Mesozoic convergence-related processes in the Intra-Pontide suture zone
No full textIn Northern Turkey, the Intra-Pontide suture (IPS) zone represents an east-west trending belt of deformed and/or metamorphic rocks bounded by the Istanbul-Zonguldak Terrane (IZ) to the north and the Sakarya Composite Terrane (SK) to the south (e.g. Göncüoğlu et al., 1997). Despite its importance for the geodynamics reconstructions of the Black Sea and Eastern Mediterranean areas during the Mesozoic, the IPS zone has been poorly investigated; only recently the role of its metamorphic units during the syn-collisional evolution was explored (Marroni et al., 2014; Frassi et al., 2016; 2017)
In order to provide new insights on the Mesozoic-Tertiary geodynamic reconstruction of the southern margin of the Laurasia, we present new data from the Saka Unit from the eastern portion of the IPS. Using a multidisciplinary approach that includes lithological, structural, metamorphic and petrographic investigations, we constrained the P-T-t path during the Mesozoic subduction and consequent exhumation and accretion to Laurasia. Following the determination of mesostructures, we analysed a series of samples of metabasite and metapelite. Mineral chemistry of phases at equilibrium in the pervasive S2 foliation was determined, and PT determinations were performed through pseudosection calculation of three samples. PT conditions are within the epidote-amphibolite facies, with pressures of 1.2 ± 0.15 GPa and Temperatures 600 ± 50 °C, thus higher than those determined previously, suggesting that S2 could be a composite foliation where a progressive evolution acquired during onset of exhumation was recorded. A comparison with the PT evolutions of the nearby Daday and Domuz-Dag units, shows that they record lower T at D2 at different ages, and that the pre-D2 conditions, when they are preserved, are different in the three units.

Burial and exhumation history of the Daday Unit (Central Pontides, Turkey)
No full textIn northern Turkey, the Intra-Pontide suture (IPS) zone divides the Istanbul-Zonguldak and the continental terranes (Göncüoğlu et al. 2000). It consists of an assemblage of several oceanic and continental units characterized by different age, metamorphic imprint and deformation history. In the Central Pontides, the IPS zone is a pre- late Paleocene imbricate stack where an ophiolite unit (Ayli Dağ ophiolite Unit) and an ophiolite-bearing mèlange (Arkot Dağ Mèlange), derived from a NeoTethyan oceanic basin (the Intra-Pontide oceanic basin: Göncüoğlu et al. 2008) are associated with four metamorphic units (i.e. Saka, Emirkoy, Daday and Domuz Dağ Unit) (Frassi et al., 2016).
In the Daday Massif, the Daday Unit is an assemblage of tectonic slices having a monogenic composition (micaschists, paragneisses, marbles, actinolite-bearing schists and quarzites) derived from a supra-subduction oceanic crust (Sayit et al., 2016) and related deep-sea sediments of Middle Jurassic age. Structural analyses, P-T estimates and Ar-Ar dating allow to elaborate a P-T-t-d path (Frassi et al., 2017) in which the D1 phase was acquired during the Late Jurassic by tectonic underplating at 35-42 km of depth. The following D2, D3 and D4 phases produced the exhumation up to shallower structural levels. The high geothermal gradient detected during the D2 phase indicates that the Daday Units was exhumed during a continent arc collisional setting. The structure of the IPS zone is unconformably sealed by the upper Paleocene - Eocene deposits and lately reworked by the North Anatolian Fault Zone (D5).

No full textRegolarità e irregolarità nelle definizioni lessicografiche di lessemi aggettivali in francese
No full textDopo aver ricordato le specificità della parte del discorso dell’aggettivo che si trovano alla base delle irregolarità nel suo trattamento lessicografico e dopo aver brevemente presentato l’esempio di un progetto lessicografico che contribuisce a porre fine all’irregolarità nel trattamento della definizione lessicografica dell’aggettivo, ci occuperemo di misurare tale regolarità/irregolarità tramite l’individuazione di un numero limitato di articoli legati ad entrate lessicali aggettivali in due dizionari monolingui rappresentativi della lessicografia francese contemporanea: il Trésor de la Langue Française informatisé (d’ora in poi TLFi) e il Petit Robert (d’ora in poi PR). Suddivideremo le nostre osservazioni sulla base della distinzione tradizionale fra aggettivo qualificativo e aggettivo di relazione (Bartning 1980; Riegel 1985; Goes 1999; Noailly 1999; Nowakowska 2004; Marengo 2012): ognuna di queste due categorie ha, infatti, come vedremo, specificità intrinseche proprie che influiscono sulla scomposizione, a livello lessicografico, del significato
Geochronological constraints on post-collisional shear zones in the Variscides of Sardinia (Italy)
No full textThe post-collisional tectonics in the inner zone of the Variscan belt of Corsica-Sardinia recorded a dextral transpression developed with an orogen-parallel tectonic transport. Recent works documented the presence of nearly parallel dextral and sinistral crustal-scale shear zones responsible for the exhumation of the metamorphic complexes. To constrain, for the first time, the timing of both shear zones and the timing of the transpressional shearing, zircons and monazites were collected for U-Th-Pb ages. Results indicate that the shear zones have been active at c. 320Ma in a transpressional setting, widespread in the Southern European Variscan belt
