Full textA synthesis of the geologic research undertaken in the Andes of Cusco area is presented. The area lie between the NE boundary of the Western Cordillera and the SW one of the Eastern Cordillera forming the NW extremity of the Altiplano. The interpretative model which results of this study is of major importanc for the understanding of the geodynamic evolution of the Andes during Mesozoic and Cenozoic. Structural, sedimentological and petrologic data are discussed. The geodynamic evolution is controlled during paleozoic and meso--cenozoic times by a paleogeographic limit between two different kind of substratum which are in contact along a boundary corresponding to the Abancay defiexion and the Cusco-Puno threshold. The Permo-Trias represents the transition between an Hercynian regime and the Andean one. The major features of the Permo-Triassic basin are inherited structures which furtherly controlled all the Andean evolution. The area of Cusco is characterized by more than 10. 000 m of Tertiary continental Red Beds which overlie marine and continental sequences of Cretaceous-PaIeocene age. These Red Beds were deposited in synorogenic basin during the Andean deformation in compressive setting. Strike-slip motions occur between 50 and 44?My along the Cusco-Puno threshold and near the NE boundary of the South-Peruvian Mesozoic basin, and result with the transtensive opening of the RedBeds basins and the deposition of the San Jeronimo Group in the Cusco, Sicuani,Ayaviri and Puno areas and possibly as far as Northern Bolivia, and representing the first settlement of the wide Altiplanic basin. A major change in stress regime occur at about 43-40 My leading to the compressive closure of the Red Beds basin and the beginning of the conglomeratic Anta sedimentation (Inca 1 tectonic event). The boundary between the Red Beds basin and the Western Cordillera, becomes a left lateral strike slip limit as shown by the evolution of the Oligo-Miocene basins. These left lateral displacement are in good agreement with the explicative model for the Bolivian Orocline. During that time (Qechua tectonic episodes) the Neogene basins were elosed in compressive tectonic regime. Geochronologic data suggest that the magmatic activity was more or less continuous since Eocene (48 My) times. However the spatial distribution of the magmatism was subject to strong variations. The quantification of the deformation shows that the amount of shortening obtained using surface geologic data cannot explain the crustal thickness observeed using geophysical data. A model involving the emplacement of continental material by underthrusting and tectonic erosion of continental crustal slivers in the subduction zone by is proposed in order to explain the volume excess. The plate kinematic seems to exercise an influence on the Andean geodynamic evolution, particularly through the event calendar, but the major control of the deformational patterns are the main paleogeographic boundaries

Full textThis thesis, through its multidisciplinary approach and the interpretation of a large amount of industrial data, brings new elements in the understanding of foreland basin systems, especially in the Andino-Amazonian field of northern Peru. It proposes a new stratigraphic and structural model of this region, reconstructs and quantifies the history of the deformation and sedimentation that constitutes the key data to model the petroleum systems and to reduce the risks in exploration. The results show that the structural architecture of the Marañon Foreland Basin, the largest of the central Andes, evolves laterally from a wedgetop zone in the SE to a foredeep zone in the NW. In the SE, it forms a thrust wedge partly eroded, connected to the wedgetop basins of Huallaga and Moyabamba. This set constitutes a single foreland basin system, deformed by the interference of an east-verging thin-skinned tectonics and a largely west-verging tectonics. The total horizontal shortening varies between 70 and 76 km. The western vergence of this thick-skinned tectonics is controlled by the inheritance of the Gondwanide orogeny (Middle Permian). We show that it is at the origin of the important crustal and destructive earthquakes in the Moyabamba basin. The east-verging thin-skinned tectonics shows a strong shortening and is confined to the wedgetop basins of Huallaga and Moyabamba, where it is controlled by the geographical distribution of a large level of Late Permian evaporites sealing the structures of the Gondwanide orogenesis. Towards the NW, the deformation of the Marañon basin is progressively amortized, which is reflected in the transition to a foredeep type deposition zone. The deformation, although not very important, is still active and responsible for shallow earthquakes. From a sedimentary point of view, this thesis has made it possible to differentiate four foreland mega-sequences in the Marañon basin, defined from well stratigraphic correlations and regional discontinuities identified in seismic. A structural section through the Marañon-Huallaga system has been restored in three stages since the Middle Eocene to reconstruct and quantify the propagation of the foreland basin system. The four foreland mega-sequences and the sequential restoration show that the Marañon-Huallaga system developed since the Albian during two stages separated by an important period of erosion during the Middle Eocene. They recorded successively the uplifts of the western and eastern Cordilleras of the Andes of northern Peru, and that of the Arch of Fitzcarrald. From a quantitative point of view, the calculated sedimentation rates show a gradual increase since the Albian, interrupted by the erosion of the Middle Eocene. The 2D petroleum modeling, carried out from a revision of the petroleum systems and the sequential restoration of the Huallaga-Marañon system, valorizes a large part of the results obtained in this thesis by simulating the expulsion of the hydrocarbons at the different stages of the deformation of the Huallaga-Marañon system, and showing its potential trapping areas
