    The Guajira Offshore and Colombia basins are located at the boundary between the south of the Caribbean plate and the northwestern corner of the South America plate. The tectonic history of the area has been dominated by an oblique convergence between these two plates. The interactions between the plates from the Paleocene to the Recent have driving the major tectonostratigraphic and structural features of the area, generating accretion prisms and compression belts (Deformed Belt of the South Caribbean) along with major strike-slip elements of transtension and transpression. Taking this into account, the goal of this work was to perform a tectono-stratigraphic and structural analysis of the deformed sedimentary sequences in the northwestern of the Guajira Peninsula recorded in the SPAN 3800 seismic line. Four tectonic events were recognized from the interpretation of the seismic facies and reflector terminations, which show the accumulation trends of the sequences and the structures styles in the study area: 1) Extensional event from the Eocene to the Oligocene, 2) Transpression from the early Miocene to the Pliocene, 3) Transtension from the late Miocene period to the Pliocene and 4) Event of diapirism after the early Pliocene.
