Abstract:
Fingerprints of the opening of the Western Black Sea Basin and collision of Pontides and Sakarya Continent along the Intra-Pontide suture can be traced in the area between Cide (Kastamonu) and Kurucaşile (Bartin) in northern Turkey, along the southern coast of the Black Sea. The Western Black Sea Basin is an oceanic basin opened as a back-arc basin of the northward-subducting Intra-Pontide Ocean. Basement units related to this opening are represented by Lower Cretaceous and older units. The first arc magmatism related to this subduction began during Turonian times. Coeval with this magmatism, back-arc extension affected the region and caused development of horst-graben topography. This extensional period resulted in the break-up of continental crust and the oceanic spreading in the Western Black Sea Basin during Late Santonian times. During the Late Campanian–Early Maastrichtian period, the Sakarya Continent and Pontides collided and arc magmatism on the Pontides ended. After this collision, the Western Pontides thickened, imbricated and developed a mainly N-vergent foreland fold and thrust belt character since Late Eocene–Oligocene times. The palaeostress directions calculated from thrust faults of this foreland fold and thrust belt are 4.6°/156.6° for σ1, 6.4°/66.1° for σ2, and 83.2°/261.9° for σ3. The nature of the imbrication indicates that it was a northward prograding foreland system connected to a floor thrust (detachment) fault at the bottom. Field observations on curved slickenfibres support the theory that the thrust faults of this imbricated structure have transformed to oblique thrusts and strike-slip faults over time.

Abstract:
Devonian in Turkey — a reviewThe Devonian Period is represented in Turkey by almost complete non-metamorphic sections of more than 1000 meters, which exhibit varying lithofacial associations. They are parts of thick Paleozoic sedimentary successions in the Pontides, Taurides and Arabian Plate. The tectonic setting and the paleogeographical origin of these terranes is different. Therefore, the litho- and biostratigraphy and facies characteristics of these Devonian successions would enable a comparison and a paleogeographical assignment of these tectono-stratigraphic units. Devonian successions of the Arabian Plate and of the Taurides are represented by facies associations ranging from tidal flat to a deep shelf. Whereas, those of the Istanbul and Çamdağ-Zonguldak areas in the Pontides by a deepening upward sequence from a shallow shelf into a basin and a stable shelf, respectively. The Devonian of the Arabian Plate and the Taurides can surely be assigned to Gondwana. A Peri-Gondwanan (Avalonian) setting is suggested for the paleogeographic position of the Devonian of the Pontides.

Abstract:
The production of Cu-Zn from volcanogenic massive sulfide (VMS) deposits in the eastern Pontides began in the early 1900s, with the exploitation of high-grade ores scattered across the district. The district still possesses economically important blind VMS and associated sulfide deposits. Careful descriptive documentation of the typical features of these VMS ores illustrated the geological characteristics that are important in identifying ore localities and can be used to define exploration targets. The eastern Pontide VMS deposits are examples of volcanic-hosted massive sulfide deposits that exhibit many of the characteristics typical of bimodal-felsic- type VMS mineralization. Nearly all known VMS deposits in the region are hosted by the Kızılkaya Formation, which is characterized by Late Cretaceous dacitic/rhyolitic volcanic rocks that are typically located at the top contact of the dacitic/rhyolitic pile or within the lower part of the overlying polymodal sequence containing various proportions of volcanic and sedimentary facies. Most VMS deposits are composed of a mound of high-grade massive sulfides formed above a zone of lower-grade stringer veins and disseminated mineralization. The dominant sulfide minerals in most deposits are pyrite, chalcopyrite, and sphalerite. Au also occurs in some deposits. The hydrothermal ore facies are diagnostic of subaqueous emplacement of the Pontide massive sulfide deposits that were deposited on the Cretaceous ocean floor. The immediate host lithologies associated with VMS mineralization have typically experienced intense and widespread alteration. The trace element geochemical signatures of the host rocks indicated that the Pontide VMS deposits likely formed in an extensional tectonic regime during subduction. Major lineaments and circular structures exerted fundamental controls on the locations of the VMS deposits in the eastern Pontide district. Age determinations indicated that almost all of the deposits in this region formed in a restricted time interval between ca. 91.1 and 82 Ma. The sulfur isotope compositions of the ore-forming fluids were consistent with those of fluids derived from modified seawater.

Abstract:
AbstractIn northern Turkey, the Intra-Pontide suture zone represents one of the first-order tectonic structures located between the Istanbul–Zonguldak and the Sakarya continental terranes. It consists of an E–W-trending assemblage of deformed and variably metamorphosed tectonic units, including sedimentary rocks and ophiolites derived from a Neo-Tethyan oceanic basin, known as the Intra-Pontide oceanic basin. One of these units is represented by the Daday Unit that consists of a block-in-matrix assemblage derived from supra-subduction oceanic crust and related deep-sea sedimentary cover of Middle Jurassic age. This setting was acquired during Late Jurassic time by tectonic underplating at a depth of 35–42 km associated with blueschist-facies metamorphism (D1 phase). The following D2, D3 and D4 phases produced the exhumation of the Daday Unit up to shallower structural levels in a time span running from the Albian to late Paleocene. The high geothermal gradient detected during the D2 phase indicates that the Daday Unit was exhumed during a continent–arc collisional setting. The tectonic structures of the Intra-Pontide suture zone, resulting from the previously described tectonic history, are unconformably sealed by the upper Paleocene – Eocene deposits. This tectonic setting was intensely reworked by the activity of the North Anatolian Fault Zone, producing the present-day geometrical relationships of the Intra-Pontide suture zone of the Central Pontides.

Abstract:
Abstract The Eastern Pontide Arc, a major fossil submarine arc of the world, was formed by northward subduction of the northern Neo-Tethys lithosphere under the Eurasian margin. The arc’s volcano-sedimentary sequence and its cover contain abundant fossils. Our new systematical paleontological and structural data suggest the Late Cretaceous arc volcanism was initiated at early-middle Turonian and continued uninterruptedly until the end of the early Maastrichtian, in the northern part of the Eastern Pontides. We measured ∼5500-m-thick arc deposits, suggesting a deposition rate of ∼220 m Ma–1 in ∼25 m.y. We have also defined four different chemical volcanic episodes: (1) an early-middle Turonian–Santonian mafic-intermediate episode, (2) a Santonian acidic episode; when the main volcanic centers were formed as huge acidic domes-calderas comprising the volcanogenic massive sulfide ores, (3) a late Santonian–late Campanian mafic-intermediate episode, and (4) a late Campanian–early Maastrichtian acidic episode. The volcaniclastic rocks were deposited in a deepwater extensional basin until the late Campanian. Between late Campanian and early Maastrichtian, intra-arc extension resulted in opening of back-arc in the north, while the southern part of the arc remained active and uplifted. The back-arc basin was most probably connected to the Eastern Black Sea Basin. In the back-arc basin, early Maastrichtian volcano-sedimentary arc sequence was transitionally overlain by pelagic sediments until late Danian suggesting continuous deep-marine conditions. However, the subsidence of the uplifted-arc-region did not occur until late Maastrichtian. We have documented a Selandian–early Thanetian (57–60 Ma) regional hiatus defining the closure age of the İzmir-Ankara-Erzincan Ocean along the Eastern Pontides. Between late Thanetian and late Lutetian synorogenic turbidites and postcollisional volcanics were deposited. The Eastern Pontide fold-and-thrust belt started to form at early Eocene (ca. 55 Ma) and thrusting continued in the post-Lutetian times.

Abstract:
AbstractThe results of apatite fission-track analyses of the Western Pontides of NW Turkey point to three discrete episodes of Cenozoic exhumation correlatable with major supraregional tectonic events. (1) Paleocene–early Eocene exhumation reflected the closure of the İzmir–Ankara ocean. (2) Late Eocene–earliest Oligocene exhumation was the result of renewed tectonic activity along the İzmir–Ankara suture. (3) Late Oligocene–early Miocene exhumation recorded the onset of northern Aegean extension. Samples collected north and south of the tectonic contact between the two terranes forming the Western Pontides (i.e. İstanbul and Sakarya terranes) record the same cooling events, suggesting that such terranes were amalgamated in pre-Cenozoic times.

Abstract:
Late Cretaceous–Early Eocene Tethyan evolution of western Turkey is characterized by ophiolite obduction, high-pressure/low-temperature metamorphism, subduction, arc magmatism and continent–continent collision. The imprints of these events in the Upper Cretaceous–Lower Eocene sedimentary record of western Anatolia are studied in thirty-eight well-described stratigraphic sections. During the Late Cretaceous period, western Turkey consisted of two continents, the Pontides in the north and the Anatolide-Taurides in the south. These continental masses were separated by the İzmir-Ankara Neo-Tethyan ocean. During the convergence the Pontides formed the upper plate, the Anatolide-Taurides the lower plate. The arc magmatism in the Pontides along the Black Sea coast is biostratigraphically tightly constrained in time between the late Turonian and latest Campanian. Ophiolite obduction over the passive margin of the Anatolide-Tauride Block started in the Santonian soon after the inception of subduction in the Turonian. As a result, large areas of the Anatolide-Tauride Block subsided and became a region of pelagic carbonate sedimentation during the Campanian. The leading margin of the Anatolide-Tauride Block was buried deeply and was deformed and metamorphosed to blueschist facies during Campanian times. The Campanian arc volcanic rocks in the Pontides are conformably overlain by shaley limestone of Maastrichtian–Palaeocene age. However, Maastrichtian sedimentary sequences north of the Tethyan suture are of fore-arc type suggesting that although arc magmatism ceased by the end of the Campanian age, continent–continent collision was delayed until Palaeocene time, when there was a change from marine to continental sedimentation in the fore-arc basins. The interval between the end of the arc magmatism and continent–continent collision may have been related to a northward jump of the subduction zone at the end of Campanian time, or to continued obduction during the Maastrichtian.

A área analisada neste estudo está situada próxima ao litoral do Mar Negro, região central-norte da Turquia, onde ocorre a exposição dos afloramentos da Região Central de Pontides. O intervalo estudado compreende parte do Cretáceo Superior e doCenozóico Inferior (Campaniano Inferior até o Eoceno), pertencentes à Formação Akveren. Este estudo objetiva propor modelos de posicionais para a região estudada,com base no trabalho de campo, descrição de perfis, amostragem, descrição de fácies,associação de fácies e estratigrafia. Para datação de perfis, foi utilizado o trabalho de bioestratigrafia de Kirici et al. (2007).O Cinturão Pontides é composto principalmente por carbonatos marinhos, com fauna de origem paleo-Tethyana. Os bioclastos (inclusive fragmentos de rudistas) formam barras em sigmóides progradantes, em ambientes rasos de alta energia. Lateralmente,são encontradas fácies típicas de ambiente lagunar, e fácies de talude na porção intermediária da plataforma.Há variação de biota em relação ao Cretáceo Superior e o Cenozóico Inferior. No Cretáceo, há predomínio de fragmentos de rudistas, de moluscos e de equinodermas.Os macroforaminíferos são do tipo Nummulites, Orbitolina e lepidorbitóides. No Paleoceno, os bancos bioclásticos são formados principalmente por algas vermelhas e há o aparecimento de macroforaminíferos do tipo Discocyclina. Fácies decalciturbiditos e tempestitos são caracterizadas por retrabalhamento dos grãos ebioclastos, com deposição em ambiente de alta energia.Blocos-diagrama propostos para a evolução deposicional na área têm o objetivo de destacar as mudanças na sedimentação carbonática da plataforma do Cinturão Pontides ao longo do tempo geológico, e a influência da tectônica no controle das edimentação.Durante o Campaniano Inferior/Médio, foi registrado um trato de sistemas de mar alto,com progradação das barras bioclásticas. No Campaniano Superior, ocorreu relativa queda do nível do mar, com erosão e exposição de parte da plataforma. No Maastrichtiano, ocorre elevação do nível do mar. No Paleoceno, a intensa atividade tectônica propiciou soerguimento de áreas-fonte, com intenso vulcanismo associado, ea formação de bancos bioclásticos paralelos à linha de costa. _________________________________________________________________________________ ABSTRACT
The studied area is located on the Black Sea coast, central-northern Turkey, where Pontides Belt outcrops are exposed. The studied interval belongs to Akveren Formation, a sedimentary section deposited during the Upper Cretaceous to Lower Cenozoic (Lower Campanian to Upper Eocene), as dated by Kirici et al. (2007). Theaim of this study is to present depositional models for the Pontides Belt in the studie darea, based on field geology, sampling, petrographic descriptions, facies association and stratigraphic relations. Akveren Formation is a Lower Campanian to Eocene marine carbonate sequence, withpaleo-Tethyan fauna, well exposed in Pontides Belt at Black Sea coast. Bioclasts accumulations tend to form sigmoidal progradational bars, in high energy shallow water environments. Laterally, lagoonal facies from restricted shallow waters,and slope facies from higher water depth in the external portions of the platform arealso observed.In Paleocene/Eocene, high energy shallow water bioclastic banks parallel to the coastline are formed by red algae and macroforams as Discocyclina. Some calciturbidites and tempestites were also observed, as result of reworking in higher energy transportevents.During Lower Campanian, it was registered a high level sea water system tract with progradation of bioclastic bars. In Upper Campanian, a relative sea level fall occurred,causing partial exposure and erosion of the platform. In Maastrichtian, sea level returnsto rise, but at to lower levels than found in the Campanian. Intense tectonic activityduring Paleocene uplifted the area with intense associated volcanism. The Upper Paleocene/Eocene relative sea level fall led the transport of terrigenous sediments tothe platform, which were reworked during the early stages of the transgressive systemtract.

Abstract:
Pre-Late Jurassic basement of the Central Pontides comprises a thick subduction-accretion complex, amalgamated since Late Palaeozoic. Detailed structural, sedimentological and geochemical studies reveal a number of major tectonic units, assembled through plate tectonics processes. Two oceanic basins are recognised, separated by two different tectonic units. The first is the Devrekani Metamorphic Unit, gneisses and amphibolites at the base, transgressively overlain by metamorphosed carbonates. This unit is interpreted as basement of a rifted south Eurasian margin fragment. The cover of this unit may be represented by the Palaeozoic of Istanbul and Early Mesozoic sequences of the W Pontides. The second unit is the Cangaldav g Complex, a 10 km-thick, imbricated pile of evolved volcanics and volcaniclastics, overlying oceanic basement, comprising sheeted dykes and basic lavas. This unit is interpreted as a Late Palaeozoic south-facing oceanic arc. The northern oceanic basin is represented by the Küe Complex, a structurally thickened wedge of siliciclastic turbidites, interleaved with a dismembered, supra-subduction zone ophiolite. The Küe Complex is interpreted as a Triassic to Early-Mid Jurassic subduction-accretion complex of southward polarity. The southerly basin is represented by the Domuzdav g-Saraycikdav g Unit, a Palaeozoic-Early Mesozoic subduction-accretion complex of northward polarity, comprising an ophiolitic melange in the north and an accretionary prism in the south, both metamorphosed to blueschist facies. Meta-basites are of MORB type. Structurally beneath is a collapsed Permian carbonate platform, together with its passive margin sequences, both to the north and south. Lavas associated with these passive margin sequences are of within plate-type without an identifiable subduction component. In the proposed model, Palaeotethys was subducted northwards under an active Eurasian margin during Late Palaeozoic time, giving rise to a near continental margin arc. A continental sliver was rifted off (Devrekani), related to transform and/or active margin processes, opening the Küe Basin as a back-arc basin in latest Palaeozoic-earliest Mesozoic time.

Abstract:
An integrated array of analytical methods -including clay mineralogy, vitrinite reflectance, Raman spectroscopy on carbonaceous material, and apatite fission-track analysis- was employed to constrain the thermal and thermochronological evolution of selected portions of the Pontides of northern Turkey. (1) A multimethod investigation was applied for the first time to characterise the thermal history of the Karakaya Complex, a Permo-Triassic subduction-accretion complex cropping out throughout the Sakarya Zone. The results indicate two different thermal regimes: the Lower Karakaya Complex (Nilüfer Unit) -mostly made of metabasite and marble- suffered peak temperatures of 300-500°C (greenschist facies); the Upper Karakaya Complex (Hodul and the Orhanlar Units) –mostly made of greywacke and arkose- yielded heterogeneous peak temperatures (125-376°C), possibly the result of different degree of involvement of the units in the complex dynamic processes of the accretionary wedge. Contrary to common belief, the results of this study indicate that the entire Karakaya Complex suffered metamorphic conditions. Moreover, a good degree of correlation among the results of these methods demonstrate that Raman spectroscopy on carbonaceous material can be applied successfully to temperature ranges of 200-330°C, thus extending the application of this method from higher grade metamorphic contexts to lower grade metamorphic conditions. (2) Apatite fission-track analysis was applied to the Sakarya and the İstanbul Zones in order to constrain the exhumation history and timing of amalgamation of these two exotic terranes. AFT ages from the İstanbul and Sakarya terranes recorded three distinct episodes of exhumation related to the complex tectonic evolution of the Pontides. (i) Paleocene - early Eocene ages (62.3-50.3 Ma) reflect the closure of the İzmir-Ankara ocean and the ensuing collision between the Sakarya terrane and the Anatolide-Tauride Block. (ii) Late Eocene - earliest Oligocene (43.5-32.3 Ma) ages reflect renewed tectonic activity along the İzmir-Ankara. (iii) Late Oligocene- Early Miocene ages reflect the onset and development of the northern Aegean extension. The consistency of AFT ages, both north and south of the tectonic contact between the İstanbul and Sakarya terranes, suggest that such terranes were amalgamated in pre-Cenozoic times. (3) Fission-track analysis was also applied to rock samples from the Marmara region, in an attempt to constrain the inception and development of the North Anatolian Fault system in the region. The results agree with those from the central Pontides. The youngest AFT ages (Late Oligocene - early Miocene) were recorded in the western portion of the Marmara Sea region and reflect the onset and development of northern Aegean extension. Fission-track data from the eastern Marmara Sea region indicate rapid Early Eocene exhumation induced by the development of the İzmir-Ankara orogenic wedge. Thermochronological data along the trace of the Ganos Fault –a segment of the North Anatolian Fault system- indicate the presence of a tectonic discontinuity active by Late Oligocene time, i.e. well before the arrival of the North Anatolian Fault system in the area. The integration of thermochronologic data with preexisting structural data point to the existence of a system of major E-W-trending structural discontinuities active at least from the Late Oligocene. In the Early Pliocene, inception of the present-day North Anatolian Fault system in the Marmara region occurred by reactivation of these older tectonic structures.

Abstract:
The analysis of apatite fission tracks is applied to the study of the syn- and post-collisional thermochronological evolution of a vast area that includes the Eastern Pontides, their continuation in the Lesser Caucasus of Georgia (Adjara-Trialeti zone) and northern Armenia, and the eastern Anatolian Plateau. The resulting database is then integrated with the data presented by Okay et al. (2010) for the Bitlis Pütürge Massif, i.e. the western portion of the Bitlis-Zagros collision zone between Arabia and Eurasia. The mid-Miocene exhumation episode along the Black Sea coast and Lesser Caucasus of Armenia documented in this dissertation mirrors the age of collision between the Eurasian and Arabian plates along the Bitlis suture zone. We argue that tectonic stresses generated along the Bitlis collision zone were transmitted northward across eastern Anatolia and focused (i) at the rheological boundary between the Anatolian continental lithosphere and the (quasi)oceanic lithosphere of the Black Sea, and (ii) along major pre-existing discontinuities like the Sevan-Akera suture zone.The integration of both present-day crustal dynamics (GPS-derived kinematics and distribution of seismicity) and thermochronological data presented in this paper provides a comparison between short- and long-term deformation patterns for the entire eastern Anatolia-Transcaucasian region. Two successive stages of Neogene deformation of the northern foreland of the Arabia-Eurasia collision zone can be inferred. (i) Early and Middle Miocene: continental deformation was concentrated along the Arabia-Eurasia (Bitlis) collision zone but tectonic stress was also transferred northward across eastern Anatolia, focusing along the eastern Black Sea continent-ocean rheological transition and along major pre-existing structural discontinuities. (ii) Since Late-Middle Miocene time the westward translation of Anatolia and the activation of the North and Eastern Anatolian Fault systems have reduced efficient northward stress transfer.

Abstract:
The Izmir-Ankara-Erzincan suture zone (IAEZ) in the Central and the Eastern Pontides, N Turkey comprises a stack of mainly Upper Cretaceous-Early Tertiary thrust sheets that record the development of: 1) a subduction­-accretion complex; 2) a rifted continental margin volcanic arc and associated fore-arc basin, and 3) a backarc basin and its sedimentary fill. Alternative tectonic models are considered in this thesis in the light of structural, sedimentary, igneous geochemical and palaeontological evidence. A tectonostratigraphic revision of the Late Cretaceous-Early Tertiary Neotethyan units in the Central and Eastern Pontides, combined with new biostratigraphic ages is used to constrain the timing of events associated with the assembly of the suture zone. All of the Late Cretaceous Neotethyan units exhibit a pervasive north-vergent shear. The age of north vergent deformation is constrained by the oldest overlying sediments (Kadikizi Formation and Sipikör Formation) as pre-Eocene. Large-scale southward thrusting followed, forming the present thrust stack. Whole-rock geochemical analyses of basic igneous rocks obtained by X-ray fluorescence indicate the presence of a volcanic arc within the suture zone. The geochemistry of the Neotethyan ophiolites (found to the north of the arc units in both areas) suggests they may represent emplaced backarc basin lithosphere. Screens of metamorphic rocks within the ophiolite in the Eastern Pontides, together with geochemical evidence for a partially enriched mantle source of arc volcanic rocks in the Central Pontides suggest that the arc-backarc system formed by rifting of the continental margin of Eurasia. Using petrographic evidence thick (<1500 m) sedimentary successions found within the suture zone are interpreted as arc apron, forearc, backarc and syn-collisional basins respectively. It is inferred that Neotethys was subducted northwards beneath the Eurasian margin associated with oceanwards trench-retreat, development of a volcanic arc and a backarc basin during Late Cretaceous time.

Abstract:
L’étude propose une description synchronique de la langue gréco-pontique (dialecte de la xaldhia) telle qu'elle est encore pratiquée par des personnes déplacées de Turquie orientale et vivant en Grèce depuis 1924. L’étude est divisée en trois parties : 1) une introduction générale au groupe étudié, 2) la description grammaticale de la langue, 3) un corpus traduit et commente. - dans l'introduction sont présentes les grands traits de l'histoire du groupe ainsi que les conditions d'enquête sur le terrain. - la description grammaticale propose une analyse phonologique de la langue, suivie de la morphosyntaxe. Cette dernière présente d'abord la description du groupe nominal du point de vue morphologique, puis le syntagme verbal. Une attention toute particulière est portée au système aspectuel, aux structures syntaxiques et aux mécanismes du marquage énonciatif. Le dernier chapitre de la morphosyntaxe expose le système des marqueurs spatiaux qui constituent une originalité indéniable de la langue, tant par leur nombre que par les spécifications sémantiques qu'ils expriment. - l'étude se termine sur un corpus de textes divers qui illustrent le fonctionnement réel des règles présentées dans la grammaire. Outre leur intérêt strictement linguistique, les textes se réfèrent a des aspects saillants de la société pontique et permettent ainsi de resituer la langue décrite dans le contexte socio-historique ou elle s'est développée
The study in object gives a synchronical description of the pontic Greek language (dialect of xaldhia) spoken in Greece since 1924 by exchanged populations from eastern turkey. The work is divided in three sections : 1) general introduction to the pontic speaking group, 2)descriptive grammar of the language, 3) an extent sample of the corpus, with translation and comments. - the introductive section gives short historical survevy of the pontic area, with an exposition of the field-work conditions. - the grammatical section describes first the phonological structures and, after that, the morpho-syntactic structures of pontic. The latter begins with the description of the morphology of n phrases and of the v phrases. The work gives a very particular attention about the aspectual system and the relations between syntactic structures and enonciative markers. The last chapter looks upon the patterns of spatial markers, which are a rather original feature of the language. - The work ends with a corpus constituted by several texts exemplifying the main grammatical rules explained above. Besides their intrinsic linguistic weight, the texts are also important by giving basic informations about crucial issues of pontic society and they give the possibility to sketch out the socio-historical context of the described language

Abstract:
La thèse " Homo Pontifex et Pontifex Oppositorum, Créativité, Imaginaire et Heuristique" se propose d'analyser les trois domaines de pertinence de la créativité, de l'imaginaire et de l'heuristique (ou science de la découverte) à partir de la notion de construction et/ou de découverte du sens dans l'anthropologie et l'épistémologie. Ces trois notions de sens sont décrites comme : celle du domaine de la structure de la personnalité (du sujet, du moi, de l'individu) comme non encore immergé dans le tissu social: cette structure est décrite dans la thèse par le mythe de Narcisse : celle du domaine de la structure sociale ayant trait aux valeurs, codes, lois et règlements érigés par cette société pour organiser la " civilité " et le vivre ensemble : cette structure est décrite dans la thèse par le mythe de Babel ; celle du domaine de l'approche technico-scientifique des sciences dites exactes et ayant trait à l'élaboration de codes et de lois scientifiques et techniques conçus pour mettre en application les lois de la nature: cette structure est décrite dans la thèse par le mythe d'Icare.
