The Colombian Basin is located in the Caribbean Sea, in a zone with different tectonic features as Hess Escarpment, the Mono Rise, the South Caribbean Deformed Belt and Beata Ridge. The main sediment source is the Nicaraguan Rise and the Magdalena Delta (Bowland, 1993). In previous works a transtensive structural style has been proposed while in other areas this structural style is compressive (Bowland, 1993). The "Backstripping ID" technique is applied with seismic and well data, allowing to propose a tectonic subsidence associated with an environment of passive margin. It is also proposed an important tectonic subsidence during Late Cretaceous, a reactivation of tectonic subsidence through Miocene‐Holocene time and a pull‐ apart basin aproximately 49 Ma ago.
