Повний текст джерелаAnalogue models for the formation of pull-apart basin have involved basal discontinuities that transmit upward the movements and stresses into the overlying cover. Here we present a series of models realized according to an innovative conceptual model that allows the formation of pull-apart basins above a viscous layer, under the sole effect of lateral movement in the cover, independently of the basement.. This work is inspired by a natural example, the El Hamma-Gabes basin, , in central Tunisia.This Basin is an extensional relay zone between two main strike-slip corridors (CCP) of a N100-110 trend. These corridors are the surface expression of the crustal shear zone called "South Tunisian Accident". They are marked by right-lateral transtensional slip during the N80 extensional episode during the Upper Cretaceous, and right-lateral transpressional kinematics during the N140 compression episode during the Neogene. These movements ensured and maintained the extension of the relay zone during both extensive and compressive tectonic events. In the relay zone the sedimentary cover is directly coupled with its pre-triassic basement, in its southern part in the absence of the upper Triassic evaporites.The sub-surface structures shows a horst-and-graben system that connect to the main strike-slip corridors (CCP). Two mega-grabens are identified: the El Hamma graben to the west and (2) the Chenchou graben to the east, separated by the J. Hallouga Horst. Each one of these grabens is internally structured into a sequence of smaller-scale horsts and grabens. In vertical sections, "hourglass" structures formed by the along-strike interconnection of grabens affecting the Upper Cretaceous series develop in the northern part of the relay zone. These structures have an amount of extension greater than that in the southern part, and seem to result from greater decoupling between the cover and basement related to the presence of U Triassic evaporitic deposits in this northern part of the relay zone.Analogue models show that: 1- When a basal viscous layer (silicone) is uniformly distributed across the entire relay zone, the pull-apart basin that forms comprises two grabens, each one connected to the frontal end of one of the (CCP). The boundary faults of these structures have curved traces. Their obliquity is that of Riedel-R-type faults at the junction to the (CCP), and becomes accentuated to take the orientation of Riedel-R'-type faults, away from it. Diapirs occur locally along the graben axes. Restoration of the deformation stages allows us to evidence three successive stages of diapirism: reactive stage associated with the opening of the graben, active and then passive synkinematics. Collapse of the diapir roof occurs at an advanced stage of deformation once the salt layer is depleted but extension continues. The "hourglass" structures develop in the syntectonic layers by upward propagation of normal faults and their interference.2 - In models with lateral density change in the décollement’s density and viscosity, the amount of extension in the relay zone appears to be greater in the area having the lowest density. The graben connected to the (CCP) on the side of this zone is more structured. Also, hourglass structures appear only in this high extension zone. There, diapirism may occur at the junction between the pull-apart basin and the (CCP) on this same side.A Digital Images Correlation analysis applied to models where the density of the layer varies, allowed us to highlight, in a quantitative and illustrated way, the distribution of the displacement fields and of the deformation rate, its spatio-temporal evolution as well as the relation between this evolution and the rheology of the detachment level

Повний текст джерелаIn this study conducted on the Mediterranean coast of Morocco, Algeria, and Tunisia at an extended spatial and temporal scale (2200 km of coastline and about 100 years), we determine, using a "source-to- sink ", the existing relationships between erosion produced in watersheds and sediment transported in suspension by wadis, with the redistribution of these sediments along the shoreline. We propose a new empirical model of suspended sediment transport along the watersheds of our study site. We then determine the impact of dams on the sediments, and then quantitatively estimate the sedimentary contributions to the sea. We analyze the morphological characteristics of the littoral according to its geometry and the morphodynamic indices from the literature . After mapping the position of the coastline at different periods, the kinematics of the shoreline is determined, as well as the shoreline drift. These analyzes are based on the concept of a littoral cell. We conclude with a general synthesis before drawing the main conclusions on the relations between watersheds and coastal cells, such as (1) the role of precursor and sediment buffer played by deltas to limit the erosion of beaches in the sector (3) the links between sediment inputs from pre-barrage wadis, minus the volume of sediment moved by the coastal drift, with the size of the deltas and the number of coastal bars

Повний текст джерелаThe sedimentology and tectonics and their relationship of the Paleozoic series that fill the Ghadames basin and its northern extension consisting of the Jefarah basin in Libya and Tunisia was studied. These formations belong to the Gondwana cycle and are typically interpreted as being deposited in a cratonic basin truncated by the Hercynian unconformity. This study is based on wells. The stratigraphic correlation between the wells is based on the definition of second order cycles. This allowed to produce isopach maps of facies distributions and to reconstruct the paleogeography of the different stratigraphic units. These data allow to address the nature of the deformation and also clarifies the behavior of active high regional areas during the Palaeozoic. The Paleozoic succession in the Ghadames and Jefarah basins can be divided in to five first order sequences, bounded by major tectonic unconformities with sequence duration of 40 - 70 Ma. Within these five sequences eighteen second order sequences (10 - 40 Ma) were differentiated, describing Sequence Boundaries (SB), Maximum Flooding Surfaces (MFS) and sedimentological characteristics. Twenty six wells with its geological well reports and well logs have been used in the study area, i.e. the Ghadames and Jefarah basins (Libya) illustrate how reservoir properties changes laterally and vertically through time (from a proximal to a distal sitting). Two softwares were used, JLog (version 4) petrophysical software for reservoir property analysis and PETREL (Schlumberger software 2014 version) for constructing stratigraphic correlation models. The Paleozoic reservoirs in the study area are spread over a large range of siliciclastic reservoirs with the prospective section extending from Cambrian to Permian. Hydrocarbons within the Ghadames and Jefarah basins originated from two major source rocks: i.e. the Lower Silurian Tanezoft Formation and Middle-Upper Devonian Aouinat Ounine Formation. The nine main Paleozoic reservoirs are respectively the Hassaouna, Haouaz and Memouniat Formations (Lower Paleozoic), Acacus, Tadrart, Ouan Kaza and Tahara Formations (Middle Paleozoic) and M’rar and Asadjefar Formations (Upper Paleozoic). Six stratigraphic cross sections through the area have been reconstructed to illustrate the vertical and lateral reservoir extensions. The dataset demonstrates that the Paleozoic reservoir properties are influenced by both, depositional facies and position within the paleogeographical setting (from proximal to distal part)
