Texto completo da fonteLacustrine deposits are extensively investigated because they play a pivotal role as environmental recorders and host valuable economic resources. However, chronostratigraphic reconstructions in these settings are usually hampered by the scarcity of data required to establish the depositional age of the system. The prime objective of this PhD project was examining benefits and limitations of carbonate U-Pb (LA-ICPMS) dating (LAcarb) as new chronostratigraphic tool for lacustrine deposits. The second objective was to investigate the dating potential, in terms of dating success and time resolution, of various carbonate types and mineralogies with the aim to better organize future LAcarb based research. To achieve these goals, depositional (microbialites, ooids, oncoids) and early diagenetic carbonate phases of known absolute age were collected from two lacustrine settings: the Ries Crater basin (Miocene, SW Germany) and the Yacoraite formation (Fm.) from the Salta rift basin (Cretaceous-Paleogene, NW Argentina). A sedimentologic and diagenetic study based on petrography and Oxygen (O) and Carbon (C) stable isotope analysis allowed to select carbonate phases that most possibly preserved the pristine U-Pb geochemical composition and consequently inform on the timing of deposition. In the Ries Crater basin, LAcarb provided accurate ages that allowed chronostratigraphic correlations at a time resolution of the 3rd order stratigraphic sequence (0.5–5Ma). In the framework of the Yacoraite Fm., two depositional age depth model were obtained along a stratigraphic section. One derived from zircon (ash layer) geochronology (maximum depositional age depth model; MDA depth model) and the other from LAcarb (minimum depositional age depth model; MIDA depth model). The two models remarkably overlap and describe the same sedimentation rate dynamic with a time resolution between 0.9 and 2% (2σ). The revised depositional age of the Yacoraite Fm. was then integrated in a chronostratigraphic model merging biostratigraphic, chemostratigraphy and magnetostratigraphy data from literature. Accordingly, the KPg limit was interpreted to be located in the Yacoraite Fm. whereas the two Paleocene-Eocene hyperthermals (Paleocene-Eocene Thermal Maximum, PETM; early Eocene Climate Optimum, EECO) were identified in the two overlying formations. A statistical analysis was achieved based on the ages of 80 carbonate phases from the Yacoraite Fm. Microbialites provided the lowest dating success (41% ages consistent with the MDA depth model) and age precision (2σ < 10%) in contrast with lacustrine cements that yielded the highest dating success (64% ages consistent with MDA depth model) and age precision (2σ < 3%). Furthermore, calcitic phases usually provided more precise ages than dolomitic phases. The better comprehension of potentialities and limitations of LAcarb acquired in this PhD allowed to propose a workflow to build a robust depositional age depth model in lacustrine settings. Three possible perspective scenarios were introduced: 1) the study of the Ries Crater basin as analogue of paleolakes on Mars; 2) the use of LAcarb to select pristine carbonates for chronostratigraphic studies; and 3) basin scale chronostratigraphic correlations in the Yacoraite Fm

Texto completo da fonteAbsolute chronological constraints on the different events and processes that have shaped the Earth constitute a major challenge in numerous realms in Earth and Environmental sciences. In particular this is the case for sedimentary basins that play a major economic role as being source of important hydrocarbon resources. The objective of this thesis is to develop absolute uranium-lead dating methodology on secondary carbonate minerals. This ubiquitous mineral phase in petroleum reservoirs testifies their complex geodynamic and diagenetic histories. In this study, several developments were implemented in order to circumvent the limits of U-Pb methodology. Innovative analysis techniques such as laser ablation coupled with SF-ICP-MS or ion probe were tested to increase the spatial resolution of the U-Pb analysis by several orders of magnitude. These methodologies coupled to the more traditional isotope dilution was successfully applied in different oil exploration context allowing to bring absolute constraints on key diagenetic events such as creation/preservation of reservoir properties or hydrocarbon migration. The results obtained during this study allowed to draw a synthetic model of the most favorable contexts for U-Pb method and gives an overview of the U-Pb dating potential to secondary carbonates applied to petroleum reservoirs

Texto completo da fonteCold seeps are common features which correspond to localized sites for methane-rich fluid release. Fluid expulsions are generally associated with abundant precipitation of authigenic carbonates. In order to better constrain fluid origin and composition, this PhD presents the results of mineralogical, isotopic (d13C, d18O and 87Sr/86Sr) and geochemistry (REE) studies on authigenic carbonates from various fluid-venting features (mud volcano, diapir, and cold seep) of the Niger Delta. The d18O values of authigenic carbonates indicate that some precipitated in isotopic equilibrium with present day bottom water conditions, while others have values that are very far from the equilibrium with present day bottom water conditions. The d13C values suggest different contributions of fluids characteriez by distinct d13C signatures. The isotopic composition of strontium also reveals diverse contribution of fluids. Aragonite concretions exhibited very similar shale-normalized REE patterns that closely resembled those of anoxic pore-water in sub-surface marin sediments. The magnesian and dolomite concretions displayed a wide range of HREE patterns. Our results showed that the REE composition of carbonates controlled by the fluid composition and by changes of alkalinity. Experimental results show that there is no fractionation during the precipitation of aragonite and calcite, but as magnesium and temperature play a role in the incorporation of rare earths. Data U/Th show that pockmark is active since at least 8000 years and ther has been a recent sinking of the SMI

Texto completo da fonteRelics of an intra-oceanic arc system are exposed in the Anti-Atlas in southern Morocco, in the Sirwa and Bou Azzer windows. Both of these areas form a highly tectonized patchwork made of a back-arc ophiolitic sequence to the north thrusted onto accreted arc complexes to the south. These arc complexes (Tachakoucht, Tazigzaout and Bougmane complexes) are made of granodioritic gneisses and amphibolites with typical oceanic arc signature and for which igneous ages range from 750 to 730 Ma. These magmas were buried, deformed and metamorphosed under MP-MT conditions in Tachakoucht (700°C - 8kbar) and HP-MT in Bougmane (750°C - 10 kbar) prior to several magmatic events dated at 700 and 650 Ma and the intrusion of hydrous basic magmas (hornblende gabbros, hornblendites) with oceanic arc signatures. This episodic magmatism strongly perturbed the thermal regime of the arc leading to the granulitization of the host rocks at different levels of the arc crust and to the genesis of intermediate to felsic magmas (granodioritic to granitic). These ones have been segregated through the crustal section intruding both stacked paleo-arc and ophiolitic remnants. This field, petrological, geochemical and geochronological study established that oceanic arc magmatism in the Anti-Atlas occurred in three flare-ups on a 120 Ma long time span (760 to 640 Ma). The growth of the arc was controlled and driven both by successive magmatic inputs and intra-oceanic tectonic thickening processes while final collision of the intraoceanic system with the West African Carton occurred later, around 630-600 Ma

Texto completo da fonteThe knowledge of pressure - temperature - time paths in metamorphic rocks is necessary to the understanding of orogenic belts evolution. U-Pb method is commonly used for dating metamorphic events, but the link between metamorphic conditions and ages obtained on zircon is not straightforward. Oxygen isotopes are proposed in this study for likening zircon to garnet growth in metamorphic rocks of the Aegean domain. The study of four samples from Naxos island showed that this correlation is possible if (i) isotopic equilibrium of oxygen is reached between garnet and zircon during their formation and (ii) garnet and zircon remained in closed system for oxygen and lead after their formation. This method permitted to date the beginning of the exhumation of metamorphic rocks from Naxos between 40 and 60 Ma, and the beginning of the retrograde path between 13 and 19 Ma. The preferential formation of zircon between 40 and 60 Ma in rocks localised in schist rich zones indicate that pressure and fluid circulation are the parameters that triggered zircon formation during the metamorphism
