Modelado Flexural 3D de la cuenca Llanos Orientales de Colombia
Los Llanos Orientales de Colombia corresponden a un sistema de cuenca antepaís que registró el inicio del pulso tectónico más reciente a partir del Mioceno (Campos, 2011) influenciado en gran medida por la colisión y acreción del bloque Chocó en el Noroeste de Suramérica en el Mioceno medio (Vargas...

description |
Los Llanos Orientales de Colombia corresponden a un sistema de cuenca antepaís que registró el inicio del pulso tectónico más reciente a partir del Mioceno (Campos, 2011) influenciado en gran medida por la colisión y acreción del bloque Chocó en el Noroeste de Suramérica en el Mioceno medio (Vargas & Mann, 2013). La deformación litosférica resultante fue representada mediante el primer modelo Flexural 3D de la cuenca de antepaís Llanos Orientales de Colombia, discretizado en 5 intervalos de tiempo desde el Mioceno medio al Presente. Con este trabajo se pretende ampliar el conocimiento en cuanto a la evolución tectonoestratigráfica de la cuenca de antepaís, mediante la identificación de las variaciones de espesor elástico (Te), modelamiento de la ubicación de las depozonas y predicciones de la configuración y movimiento del orógeno (Cordillera Oriental). Se empleó el código FLEX3DV, desarrollado en MatLab por Cardozo (2009). Este código se basa en una solución por diferencias finitas centradas a la ecuación de deflexión de una placa de espesor variable (Ventsel & Krauthammer, 2001). En el modelado Flexural 3D se integraron datos de estudios previos (e.g. mapas de espesores, secciones estructurales evolutivas). Los resultados consisten en mapas que muestran áreas de levantamiento y subsidencia del sistema Cordillera Oriental- Llanos Orientales. Estos mapas fueron comparados con modelos flexurales 2D previos realizados en el área de Los Llanos y en cuencas de antepaís adyacentes. Los modelados flexurales 3D para cada intervalo de tiempo permitieron ver una una estrecha relación entre la dirección de desplazamiento de la onda flexural modelada y los diferentes procesos del bloque que subduce desde el Mioceno medio al Presente. |

La deformación litosférica resultante fue representada mediante el primer modelo Flexural 3D de la cuenca de antepaís Llanos Orientales de Colombia, discretizado en 5 intervalos de tiempo desde el Mioceno medio al Presente. Con este trabajo se pretende ampliar el conocimiento en cuanto a la evolución tectonoestratigráfica de la cuenca de antepaís, mediante la identificación de las variaciones de espesor elástico (Te), modelamiento de la ubicación de las depozonas y predicciones de la configuración y movimiento del orógeno (Cordillera Oriental). Se empleó el código FLEX3DV, desarrollado en MatLab por Cardozo (2009). Este código se basa en una solución por diferencias finitas centradas a la ecuación de deflexión de una placa de espesor variable (Ventsel & Krauthammer, 2001). En el modelado Flexural 3D se integraron datos de estudios previos (e.g. mapas de espesores, secciones estructurales evolutivas). Los resultados consisten en mapas que muestran áreas de levantamiento y subsidencia del sistema Cordillera Oriental- Llanos Orientales. Estos mapas fueron comparados con modelos flexurales 2D previos realizados en el área de Los Llanos y en cuencas de antepaís adyacentes. Los modelados flexurales 3D para cada intervalo de tiempo permitieron ver una una estrecha relación entre la dirección de desplazamiento de la onda flexural modelada y los diferentes procesos del bloque que subduce desde el Mioceno medio al Presente.The Eastern Llanos of Colombia foreland basin system recorded the beginning of the most recent tectonic pulse from the Miocene (Campos, 2011). This tectonic pulse was mainly triggered by the Panama Arc accretion in Northwestern South America in the Middle Miocene (Vargas & Mann, 2013). The resulting lithospheric deformation was represented by the first 3D Flexural modeling of the Llanos Orientales basin, discretized in 5 time intervals from the Middle Miocene to the Present. This work aims to expand knowledge regarding the tectonostratigraphic evolution of the foreland basin, by identifying the variations in elastic thickness (Te), modeling the location of the depozones and making predictions about how the orogen (Eastern Cordillera) developed in the last 16 Ma. 3D flexural models were generated by using the code FLEX3DV, developed in MatLab by Cardozo (2009). This code solves the flexural equation by a centered finite differences solution for a variable thickness plate (Ventsel & Krauthammer, 2001). Data from previous studies were integrated into 3D flexural modeling (e.g. thickness maps, balanced cross-sections). The results consist of maps showing uplift and subsidence areas in the Eastern Cordillera-Eastern Llanos region. These maps were compared with previous 2D flexural model results in the study area and in adjacent foreland basins. The 3D flexural models for each time step showed a correlation between the flexural wavelength displacement direction and the slab processes from the middle Miocene until the Present.MaestríaProcesos Geodinámicos y Cuencas Sedimentarias1 recurso en línea (133 páginas)application/pdfspaUniversidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - GeologíaDepartamento de GeocienciasDepartamento de GeocienciasFacultad de CienciasBogotáUniversidad Nacional de Colombia - Sede Bogotá550 - Ciencias de la tierraModelo Flexural 3DCuenca antepaísIsostasiaEspesor elásticoRigidez de la LitosferaEvolución tectonoestratigráficaLlanos Orientales de Colombia3D Flexural ModelingForeland basinIsostasyElastic thicknessLithosphere rigidityTectonostratigraphic evolutionEastern LlanosColombiaModelado Flexural 3D de la cuenca Llanos Orientales de ColombiaTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/version/c_fa2ee174bc00049fTexthttp://purl.org/redcol/resource_type/TMAlberty, M.
