The geomorphologic evolution of this area is characterized by the existence of at least two main tectonic events, which has been studied from morphometric and fracture analysis. The data indicate the existence of an initially normal left-lateral stress regime during Lower Cretaceous, followed by a left-lateralstress regime during Paleogene. Finally it is inferred the existence of a younger rigth-lateral stress regime that might correspond to a pleistocene tectonc event reported in ohter areas. It is suggested that this methodology can also be applied to similar areas in Colombia, specifically whwrw there are outcrops of igneous or metamorphic basement.

The change took place after the infilling of Cispata Bay, the site of the previous delta. The infilling is studied with two isopach maps made from bathymetric charts from 1762, 1849, and 1938. The isopachs help show the distribution of the sediments inside the bay and provide estimations of sedimentation rates. The results are compared with the sediment distribution and estimated sedimentation rate found for the delta at Tinajones. The results suggest that the infilling of the Cispata Bay produced the river avulsion and the change to Tinajones and probably was accelerated by sediments that came from outside the bay.
