Summary The Eastern Cordillera is bounded by the Middle Magdalena Valley basin in the west and by the Llanos Foothills to the east. It is commonly interpreted to have grown from a Mesozoic rift basin that became inverted during the Cenozoic Andean orogeny both the eastern and western margins of the Eastern Cordillera were thrust over the adjacent basins during inversion, resulting in a complex combination of thick-skinned and thin-skinned structures. The geological evolution of the rift basins in the study area is key to understanding the structural configuration of related basins such as the Middle Magdalena Valley. The influence on the geometry and evolution of the syn and post – rift, has been only detected at structural levels below the normal range of seismic acquisition and design, nevertheless, the the exposure of Mesozoic units and structures, allowing to revisit and collect stratigraphic and structural data. In order to correlate with subsurface data, the timing and the kind of fault displacements, and the implications in the MMV development. However, these methods provide a constrained approach of the geological evolution, and they require verification with other tools as; date synrift units with U-Pb to detect timing and integrate it in basin modeling.
