Seismic-stratigraphic analysis of multichannel seismic-reflection profiles indicates that the sedimentary section in the western Colombian Basin comprises five principal units. The deposition of these units was strongly influenced by the basement relief of an oceanic plateau. The five units define three depositional episodes, the middle three units defining a single episode. The depositional history of the western Colombian Basin supports plate-tectonic models of this area based on the insertion of Pacific lithosphere. -from Author
