“…Foraminifera assemblages from the Arroyo Piedras section were first analyzed by Redmond (1953), who reported some normal neritic benthonic foraminifera species apparently diagnostic of a Caribbean Sea e Pacific Ocean seaway connection. However, Bordine, 1974;Pince et al, 2003) suggest that the Magdalena River paleodrainage probably changed from discharging sediments in front of the Santa Veronica beach (A), to a northwest e southeast paleodrainage direction, delivering sediments around Galerazamba area (B). Note the location of the present Magdalena River mouth (C) and the Sierra Nevada de Santa Marta (SNSM).…”

“…Tectonics could affect the Magdalena paleo-River by a) increasing the sediment yield in response to the upheaval of the northern Andes during the Early Pliocene (e.g. Van der Hammen et al, 1973;Kellogg and Bonini, 1982;Kolla et al, 1984;Pince et al, 2003;Mora et al, 2008). b) Altering the potential sediment reception areas near to the Arroyo de Piedras site (e.g.…”

“…The Magdalena delta system apparently changed its course during the Pliocene (e.g. Bordine, 1974;Kolla et al, 1984;Pince et al, 2003). This migration apparently coincided in part, with three regional events: (1) a rapid sealevel fall (e.g.…”

“…Probably during the middle Pliocene, the drainage system changed toward the north (e.g. Hoorn et al, 1995;Pince et al, 2003). The Magdalena paleo-River mouth would have migrated to an ancient major channel near Calamar, thus flowing northwestward near Luruaco and discharging into the Caribbean Sea near Galerazamba (Fig.…”

“…Previos estudios de la morfología y estratigrafía del abanico del Magdalena muestran fuerte evidencia que, a pesar de su configuración a lo largo de un margen activo (subducción del Caribe), el abanico presenta características similares a los que se encuentran en los grandes sistemas deltaicos de los mayores ríos del mundo a lo largo de márgenes pasivos (Romero-Otero et al, 2015). Además, trabajos previos (Pirmez et al, 1990;Pince et al, 2003), demuestran que hay una relación con los cambios del curso de la desembocadura del Río Magdalena con el tectonismo regional.…”

RESUMEN El propósito principal de esta investigación es esclarecer el estado isostático del área de abanico del Rio Magdalena a partir de la interpretación de anomalías de campos potenciales en la Cuenca Colombia con el fin de profundizar el conocimiento teórico sobre los procesos geodinámicos y el fenómeno de la isostasia. Las investigaciones sugieren que la condición isostática de la corteza está fuertemente afectada por la correlación entre la anomalía gravimétrica de aire libre (FAGA) y los efectos gravimétricos del terreno (TGE). El análisis e interpretación incluyen el procesamiento y la elaboración de mapas de las anomalías gravimétricas y magnéticas. Las correlaciones e interpretaciones de las anomalías gravimétricas confirman perturbaciones isostáticas a lo largo del margen noroccidental colombiano y la Cuenca Colombia. La validación de los resultados se ha realizado mediante el modelamiento directo e inverso de datos de gravimetría y magnetometría y posterior comparación con modelos de espesor de corteza a partir de datos sísmicos. Los modelos sugieren un bajo ángulo de subducción y la deformación elástica de la placa Caribe, el cual se muestra afectada por la carga sedimentaria del paleo-delta del río Magdalena, las provincias geotectónicas de los cinturones del Sinú-San Jacinto y la corteza continental.

The area of influence of the Magdalena submarine fan, offshore northern Colombia, is a global frontier basin with sparse well control and only publically available 2D seismic from which to conduct exploration surveys. We have conducted a 2D seismic stratigraphic study to advance knowledge of the tectonostratigraphic evolution of this area and, furthermore, optimize exploration concepts to include stratigraphy and sedimentology to enhance such opportunities. Eight third-order seismic sequences from the early Miocene to Holocene comprise the stratigraphic record. Seismic character, thickness, and sedimentary processes vary in each sequence based on the area of deposition. Three geomorphologic areas are subject to deposition: the Tayrona depression, the undeformed central Magdalena fan and deformed wedges on either side of the fan. From oldest to youngest, sequences I to V represent bathyal paleo-environments that were deformed during the late Miocene Andean phase. Deformation of these sequences is thin skinned thrust sheets, where the main basal detachment corresponds to Oligocene shale. This deformation continued until the middle Pliocene, when sequence VI and VII were deposited on the Magdalena Fan mainly as mass transport and channel-levee deposits. Sequence VIII represents the record from early Pleistocene to the present time. From early Pliocene to present, erosion was mainly the product of submarine fan activity and bypass in areas of high slope, whereas for older deposits, erosion was caused by exposure to subaerial conditions. Superimposed on the third-order sequences are fourth-order sequences, which reveal a relative (tectonic-eustatic) sea level increase from Early Miocene to middle Late Miocene (Tortonian) time, followed by a lowstand event that extended until Holocene time. Potential reservoirs embedded within the sequences include sheet sands, channel fills, and levee-overbank. Other components of the petroleum system such as a mature source rock are still under debate.
