This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The structural and stratigraphic evolution of the Lower Magdalena Basin (LMB), located in northwestern Colombia, remains controversial with several tectonic models proposed to explain its origin and development. LMB covers a total area of 41,865 km2 of an extensive, flat, and lowlying basin that is traversed by the south-to-north draining Magdalena River, the third largest river in South America. This largely featureless plain is underlain by two large sedimentary sub-basins: the 8km-deep Plato basin in the north and the 7km-deep San Jorge sub-basin to the south separated by the northwest-southeast trending Cicuco high. Using a regional dataset (wells and 2D seismic) provided by Pacific Rubiales Energy, this study defined three tectonic stages in the evolution of the Plato and San Jorge sub-basins since Oligocene to Recent time. Stratigraphic results presented in this thesis for the Plato sub-basin includes a pre-Oligocene igneous and sedimentary basement overlain by six stratigraphic units from Oligocene to Quaternary age that are tied to both wells and the grid of 2D seismic reflection lines. Mapping revealed that the strike of the main normal faults controlling basin subsidence in the Plato sub-basin is northwest-southeast. Biostratigraphic control from wells show that the major period of basin-controlling normal fault movement was from Oligocene to Middle Miocene time. Mapping also shows the presence of Middle Miocene submarine canyon systems that may be the earliest evidence of regional uplift related to the collision of the Panama arc with northwestern South America. The overall evolution of the LMB is summarized as five paleogeographic maps from Late Cretaceous (66-72Ma) to Early Pliocene (5Ma).

Book Synopsis Tectonostratigraphic Evolution of the Sinu Accretionary Prism and Lower Magdalena Forearc Basin Formed Above a Shallow-dipping Subduction Zone, Caribbean Margin of Colombia by : Rocio Bernal-Olaya

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is an integrated geologic and geophysical study of the slowly converging (20 mm/yr), amagmatic, and shallowly subducting (4-8 ̊) system of the Caribbean margin of Colombia that includes both its offshore accretionary prism (Sinu belt) and its overlying deep (8-9 km) and wide (150-200 km) forearc basin (Lower Magdalena basin, LMB). Based on 29000 earthquake relocations, interpretations of ~1200 km of offshore deep-penetration seismic reflection lines recorded to depths of 20 km along with coincident gravity models, and 7000 km2 of onshore seismic reflection lines tied to 33 wells, I define an east-southeastward (110 ̊) dipping zone of shallow subduction beneath northwestern Colombia, an actively deforming accretionary prism, and an Oligocene to Recent forearc basin. Low angle subduction occurs as a 13-16 km thick Late Cretaceous oceanic plateau subducts beneath South America. Tomographic data reveal that the subducted slab exhibits an unusual negative velocity anomaly at depths greater than 80 km that I interpret as an incipient slab break off related to the clogging of the trench by the 30-km-thick Panama arc. In the accretionary prism, Pliocene-Pleistocene deformation developed on an imbricated backward breaking imbricated fan of thrust faults with out-of-sequence thrust faulting (OOST) within inner and outer parts of the prism. Inactive strike-slip faults were identified in a trench-parallel orientation where the subduction convergence direction is more oblique (>13mm/yr). In the forearc basin, I describe initial Oligocene subsidence of the forearc basin along 70 ̊-110 ̊striking normal faults that remained active until Early Miocene. An angular unconformity spanning the interval of 11 to 7 Ma seems to evidence the initiation of low angle subduction. The Lower Magdalena basin (LMB) overfills with sediments of shallow marine- transitional facies and spills offshore along the proto-delta of the Magdalena fan where up to 5 km deposited during the Pleistocene to Recent. I propose that this change from the steeper to shallowing dipping slab in the Middle Miocene led to increasing elevation of the forearc high and the western part of LMB where a clear unconformity is subsequently deformed.
