Full textThe study of vertebrate remains from the Fitzcarrald area (South Peru), and particularly that of astrapotheriid native ungulates, allowed characterising the "Fitzcarrald local fauna", restricting its stratigraphic range to the late Middle Miocene (Laventan), and showing that it evolved in the context of the Marine-like megalake Pebas complex. Faunal comparison with other South American vertebrate localities confirms the occurrence of environmental and/or geographical barriers between northern and southern South America at that time. Moreover, palynomorphs recovered in the Iquitos area (North Peru) have been interpreted as indicating a late Middle Miocene age. Their paleoenvironment was also determined as congruent to the Marine-like megalake Pebas complex. The biochronological dating and ecological interpretation of the Fitzcarrald local fauna confirm that the organization of the hydrographic network and of the current biodiversity of the Amazon basin implemented after the late Middle Miocene

Full textThe paleogeographic evolution during the Ediacaran is dominated by the dispersion of Rodinia and the assembly of Gondwana. Paleogeographic reconstructions for this epoch are still highly debated due the low amount of reliable paleomagnetic data. The most documented but also the most problematic database cornes from the continent Laurentia which displays fast large oscillations of the paleomagnetic poles from high to low latitudes between 615 and 565 Ma. Such oscillations, if interpreted as plate drift, imply extremely high plate velocities which are inconsistent with plate tectonics. Less conventional hypothesis have been proposed in literature such as the oscillation of a magnetic field dominated by an equatorial and an axial dipole or True Polar Wander episodes, the latter implying large tumbling of the bulk Earth with respect to its spin axis. If one of these two mechanisms occurred, the rapid and large oscillations observed for Laurentia should be recorded in any other rocks of the same age from other continents. In this study, we tested these hypotheses by bringing new paleomagnetic data on Ediacaran and Cambrian volcanic series from another continent, the West African Craton (WAC). We identified a Hercynian remagnetization and two paleomagnetic components which could be of Ediacaran/Cambrian age. By comparing these results with those from literature, we constructed an apparent polar wander path for the WAC where we identified a large oscillation from 615 to 565 Ma, comparable to one of those observed for Laurentia. This oscillation is also observed in other continents and is consistent with geological constraints on the relative position of these continents. Therefore, it seems that this oscillation is a global feature and implies velocities compatible with the TPW hypothesis or with the oscillation of an Earth magnetic field dominated by an equatorial and axial dipole. We tested the True Polar Wander hypothesis by integrating the paleogeographic reconstructions we propose in this study into simple mantle dynamics models. These results seem compatible with such a mechanism even if we cannot exclude that perturbations of the Earth magnetic field could have occurred during the Ediacaran

Full textAmynthas and Metaphire are two genera within the family Megascolecidae. Both of them dominate only in the Southeast and East Asia. The biodiversity richness of vegetables and animals makes Hainan Island, the southernmost part of Chine, one of the hotpots in China. However, only 35 earthworm species are reported before 2006. In terms of paleogeography, there are distinct view points on the tectonic origin of Hainan Island. The objectives of the thesis are (1) to investigate the earthworm community in Hainan Island (2) to analyze the phylogeny of these earthworms and reconstruct their ancestral states (3) to analyze the corresponding relationship of morpho-anatomical characteristics and species in Hainan Island and in its adjacent regions. Currently, earthworm species in Hainan Island amount up to 107 species and subspecies, including 71 new species and subspecies described after 2006. The phylogenetic and taxonomical analyses indicate that the morpho-anatomical characteristics under the sexual selection are the most important to earthworm evolution. Furthermore, the earthworm species of Hainan Island have affinitive to those of South China, Southeast and East Asia. Overall, our study reveals that the present distributions of pheretimoid earthworms in Hainan Island are affected by the tectonical history of this island and they are determined more or less by the paleogeographical events of South China plate and Indochina plate

Full textThe Canadian basin is among the few basins worldwide for which the nature and the geometry of the substratum, and therefore the opening mode, are still unknown. Paleogeographic models based on the few data available are subject to controversy, with different mechanisms and inception ages. According to current paleogeographic models, the margins of Canadian basin either considered as extensional or transform margins. Detailed study of their structures and chronologies is a preliminary exercise to discriminate between permissible models. The most sollicited opening model assumes a change of polarity of the overall subduction south to the canadian basin during the multiphase Brookian orogeny. The Brooks orogen is located north of the alaskan peninsula and south of the canadian basin. It constitutes one of the main assembly stage of terranes in the Northern Cordillera : docking of the Arctic-Alaska-Chukotka terrane with the peri-Pacific arcs system. Its collisional stage is deemed synchronous of the opening of the Canada Basin, which is likely to provide clues about the coupling between tectonics of the north basin and intra-Alaska Cordillera deformation. This orogen has both recorded and influenced the geodynamic history of the Canadian basin. The relative chronology of the development of the two structures is essential and any reconstruction of regional geodynamics must reconcile them in terms of kinematics and boundary conditions

Full textOn geological timescales, global climate proxies indicate that variations of large magnitude occur between the Cretaceous and the Cenozoic. On the long term, these variations are mostly determined by the equilibrium between the greenhouse gases composition of the atmosphere, primarily the CO2, and continental weathering set up by the spatial location of Earth’s landmasses. Here, the links between paleogeography and CO2 are looked upon in a climate-ice sheet interactions framework during a greenhouse period of Earth history (120 – 34 Ma). A suite of models involving both coupled and ice sheet models have been used to demonstrate that paleogeographic reorganizations have regulated the presence of ice over Antarctica during the Cretaceous. In a second time and using a similar setup, a new method for climate-ice sheet coupling have been developed and applied to the Eocene-Oligocene (EO) glaciation to yield a new scenario of ice evolution, in good agreement with data. Two feedbacks related to this glaciation and the coeval atmospheric CO2 fall are investigated. First, it is shown that the EO glaciation generates an intensification of the Antarctic Circumpolar Current. Second, within a data-model study demonstrating active Asian monsoons as old as the mid-Eocene, it is shown that the climatic change at the end of the Eocene is responsible for a reduction in the intensity of the Asian monsoon. Finally, with the aim of analysing the effect of paleogeographic changes on marine biogeochemistry during the Cenozoic, sensitivity tests to Drake Passage and Panama Seaway have been carried out

Full textDuring the Precambrian and trough the Palaeozoic, the Zagros area was part of the Arabian platform (Beydon, 1993). The Palaeozoic succession of the Zagros extends from Cambrian to well-developed Permian deposits. The study area ranges from the Lurestan to Southern Fars onshore and to the Persian Gulf offshore wells. From Ordovician to Early Permian Palaeozoic succession of the Zagros area comprises four second-order tectonostratigraphic depositional cycles separated by major unconformities. Eustatic sea-level variation is the main controlling factor for accommodation space changes, whereas in West High Zagros and Kuh e Gahkum, the role of regional and salt tectonic activities may be also important. The first cycle (Ordovician) is composed of the Seyahou (Floian-Katian) and Dargaz (Hirnantian) Formations. They are characterized by deep- to shallow-water (offshore to shoreface) siliciclastic deposits. The Seyahou Formation contains seven 3rd-order depositional sequences. The glaciogenic Dargaz Formation consists of one 3rd- order sequence. The second cycle (Early Silurian) corresponds to the Sarchahan Formation is composed of two 3rd-order depositional sequences. They are characterized by deep-marine offshore to upper offshore environments. Locally in Kuh e Gahkum the base of the Formation presented continental fan delta deposits due to the salt tectonic activity.The third cycle (Devonian) corresponds to the Zakeen Formation and divided in three 3rd-order depositional sequences. It started with the deposition of continental to near-shore marine clastic deposits. In Late Devonian, it evolved to carbonate marine deposits in the south of Fars area and the Persian Gulf. The lack of Zakeen Formation in Kuh e Surmeh and Kuh e Siah, and is presence in neighboring areas (Naura, Aghar, etc…), suggests structural salt plug activities (Jahani, 2008). This megasequence is capped by a major unconformity related to the Hercynian orogeny.The last deepening-upward cycle of the Pre-khuff succession in the study area is the Early Permian Faraghan Formation. It capped the Hercynian orogeny and deposited throughout the Zagros area from Lurestan (west) to Bandar Abbas (East) areas as well as in Persian Gulf. The Faraghan Formation divided into three 3rd-order depositional sequences and deposited in coastal plain to shallow-marin near-shore environment. Basinward, in the deeper part (e.g. Kuh e Faraghan), they are replaced by marine upper offshore deposits. The Palaeozoic succession is marked by several major unconformities associated with hiatus. They resulted from: (i) major sea level drops at the end of the Ordovician related to the Hirnantian glaciation (Ghavidel Syooki et al., 2011) and of during the Carboniferous related to the southern Hemisphere glaciation (Golonka, 2000); (ii) An uplift of the Middle East area at the end of the Silurian associated with epeirogenic movements (Ala et al., 1980; Berberian and King, 1981; Al-Sharhan and Nairn, 1997) and a major sea level drop at the end of Silurian (Al-Husseini, 1991,1992; Sharland et al., 2001; Konert et al., 2001; Haq and Al-Qahtani, 2005); and (iii) impact of the Hercynian orogeny spanning from the Late Devonian up to the Carboniferous (Al-Hosseini, 1992; Sharland et al., 2001; Konert et al., 2001, Faqira et al., 2009)

Full textThe data acquired within the framework of the MAGDATIS RNA for the period 19-18 Ky calBP allow us to raise a certain number of questions concerning the establishment of the Classic Magdalenian in southwestern France. In addition, numerous C14 dating results offer a new and more precise framework for this period, synchronous with the beginning of the Heinrich 1 climatic event and its consequences on the environment (landscapes and availability of game). At the same time, this period is marked by important social and symbolic transformations visible in different registers: richly endowed primary burials, parietal sculptures, development of human and sexual figuration, recomposition of lithic and bone equipment. The objective of this thesis is to compare technical and economic behaviors based on the examination of lithic series from the Early Middle Magdalenian (19-18 Ky calBP) with these changes in order to infer about the societal transformations of hunter-gatherer groups during this pivotal period. Several lithic series are available to carry out this project within the framework of taphonomic analyses (digitization of the St Germain or Roc de Marcamps notebooks available). A revision of the series from Marcamps, St Germain, Moulin Neuf, Combe Cullier, Petit Cloup Barrat layer 3, but also the contribution of new excavations (Laa2 and Ste Colome in Béarn) will allow us to apprehend the early Middle Magdalenian period in a new light. The geographical area is limited to southwestern France and centered on the Atlantic coast, thus also contributing to reflections on the settlement, territories and social interactions developed by these groups
