Análisis estructural del Anticlinal de Bogotá, Cordillera Oriental de Colombia: Implicaciones en el estilo de deformación del Piedemonte Llanero

Resumen

En este trabajo se describe y se discute un análisis estructural del Anticlinal de Bogotá, en donde a partir de la creación de un nuevo mapa geológico y secciones estructurales, se propone un modelo de evolución del plegamiento. El Anticlinal de Bogotá es una estructura geológica compleja con variaciones importantes en su vergencia y en su geometría en distancias muy cortas, por lo cual su formación fue asociada en el pasado a colapsos gravitacionales. El Anticlinal de Bogotá se encuentra en el Plateau de Bogotá, que hace parte de la zona axial de la Cordillera Oriental de Colombia. En este trabajo se propone que este pliegue muestra una variación lateral que evidencia diferentes etapas de deformación de un pliegue de despegue fallado con un horizonte de despegue ubicado en la Formación Chipaque. Una falla de cabalgamiento propuesta al este de la estructura de estudio podría generar el acortamiento necesario para la formación de este pliegue. El modelo propuesto podría servir como un análogo para un estado anterior de menor deformación para los pliegues observados en rocas similares del Piedemonte Llanero.

Palabras clave: Cordillera Oriental, pliegues de despegue, Piedemonte Llanero, Orogenia Andina
