“…These data also support a fore-arc basin setting in which both the oceanic and continental affinity, Upper Cretaceous magmatic arcs were being eroded and providing sediment for the marine basin to the northwest. Though evidence of Paleocene to early Eocene magmatism has not been yet found in the LMV and SJFB, it is likely that plutons of such ages exist, considering that Paleocene to early Eocene magmatism has been documented in surrounding areas such as the northern CC (Paleocene Sonsón Batholith, Bayona et al, 2012;Bustamante et al, 2017), the SNSM and the Guajira peninsula to the north (Cardona et al, 2014). If the SNSM and the northern CC were connected, as interpreted by Montes et al (2010) and Mora et al (2017), and if both the northern CC and the southern SNSM were being uplifted in the late Paleocene (Restrepo et al, 2009;Villagómez, Spikings, Mora, et al, 2011), then the most likely sources for the sediments of Sequence 2 were the ancient northern CC and southern SNSM, located to the east and southeast of the SJFB in early Eocene times.…”

“…Furthermore, the cessation of magmatism in northern Colombia would also be related to this plate tectonic readjustment, which probably took place between 56 and 45 Ma. Previous studies in the Guajira peninsula (Parashi intrusive, Cardona et al, 2014), in the SNSM (Santa Marta batholith, Mejía et al, 2008), and in the northern Central Cordillera (ANH, 2011) concluded that subduction-related magmatism in northwestern Colombia occurred only until early middle Eocene times (50-45 Ma, Bayona et al, 2012). Post-Eocene magmatism has been documented only in the central and southern Colombian Andes, where it is related to the subduction of the Nazca (Farallón) Plate under western South America.…”

Collision with and subduction of an oceanic plateau is a rare and transient process that usually leaves an indirect imprint only. Through a tectonostratigraphic analysis of pre‐Oligocene sequences in the San Jacinto fold belt of northern Colombia, we show the Late Cretaceous to Eocene tectonic evolution of northwestern South America upon collision and ongoing subduction with the Caribbean Plate. We linked the deposition of four fore‐arc basin sequences to specific collision/subduction stages and related their bounding unconformities to major tectonic episodes. The Upper Cretaceous Cansona sequence was deposited in a marine fore‐arc setting in which the Caribbean Plate was being subducted beneath northwestern South America, producing contemporaneous magmatism in the present‐day Lower Magdalena Valley basin. Coeval strike‐slip faulting by the Romeral wrench fault system accommodated right‐lateral displacement due to oblique convergence. In latest Cretaceous times, the Caribbean Plateau collided with South America marking a change to more terrestrially influenced marine environments characteristic of the upper Paleocene to lower Eocene San Cayetano sequence, also deposited in a fore‐arc setting with an active volcanic arc. A lower to middle Eocene angular unconformity at the top of the San Cayetano sequence, the termination of the activity of the Romeral Fault System, and the cessation of arc magmatism are interpreted to indicate the onset of low‐angle subduction of the thick and buoyant Caribbean Plateau beneath South America, which occurred between 56 and 43 Ma. Flat subduction of the plateau has continued to the present and would be the main cause of amagmatic post‐Eocene deposition.

“…1). However, the Cretaceous sedimentary successions from the Jarara range were metamorphosed during the Late Cretaceous (~71 Ma) and intruded during the Eocene (~50 Ma) by the Parashi pluton (Weber et al 2010, Cardona et al 2014. These events place the youngest depositional age of the Cretaceous sediments from the Alta Guajira basin and they have been related to the interaction between the Caribbean and South American plates (Weber et al 2010;Cardona et al 2014).…”

Sedimentology and chemostratigraphy of a Valanginian carbonate succession from the Baja Guajira Basin, northern Colombia

ABSTRACT:The Kesima Member of the Palanz Formation constitutes the first record of Cretaceous marine sedimentation along the Baja Guajira Basin, northern Colombia. Sedimentologic and petrographic analyses suggest a deposition along a coral reef dominated rimmed carbonate platform.87 Sr/ 86 Sr values between 0.707350 and 0.707400 suggest a Valanginian (136 -132 Ma) depositional age for the Kesima Member. A positive anomaly on the δ 13 C values of ~2.2‰ suggests that this rimmed carbonate platform registered the Valanginian Weissert oceanic anoxic event. Although the Weissert oceanic anoxic event resulted on a major drowning of the Circum Tethyan carbonate platforms, it seems to have not affected those from the Circum Caribbean, where several shallow marine carbonate platform successions crop out. The Kesima Member displays a change from an organically produced carbonate factory into an inorganically produced, ooids dominated, carbonate factory during the peak of the Weissert event δ 13 C anomaly. This change in the carbonate factory, which may represent a major perturbation of the marine carbonate budget along tropical settings during the Weissert event, coincides with a major decrease in global sea level. Finally, the age of the Kesima Member is considerably older than that of other Cretaceous carbonate successions cropping out in other northern South America sedimentary basins (i.e. Perija-Merida, Cesar-Rancheria). Differences in the timing of the Cretaceous marine incursion along northern South America, together with the differences in the Triassic-Jurassic stratigraphy of several sedimentary basins in northern South America, suggest that the Baja Guajira and Maracaibo basins remained as an isolated tectonic block separated from northern South America after the breakup of Pangea.
