“…Sonsón batholith, 6. El Bosque batholith (from ANH, ; Cardona et al, , ; Bayona et al, ; Bustamante et al, ). The northwestward motion of allochthonous oceanic terranes (up to ~1077 km between 90 and 65 Ma, in Boschman et al, ), accreted to western Colombia along major suture zones such as the right‐lateral RFS in Late Cretaceous to Paleogene times, is not shown here.…”

“…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.…”

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.

“…90 to 60 Ma (Ibáñez-Mejía et al, 2007;Restrepo-Moreno et al, 2009;Ordóñez and Pimentel, 2001;Ordóñez-Carmona et al, 2006;Leal-Mejía, 2011;Villagómez et al, 2011). This was succeeded by a Paleogene post-collisional magmatic arc which includes the Eocene portion of the Antioquia batholith (Leal-Mejía, 2011;Bayona et al, 2012;Bustamante et al, 2017). The later suggests that the continental margin was subjected to a progressive thickening since its interaction with the Farallón plate, and that may be recorded by the Antioquia batholith.…”

The Antioquia batholith represents the magmatic record of the interaction between the Farallón and Caribbean plates with the NW part of the South American Plate during the Meso-Cenozoic. Several authors have reported zircon U-Pb ages and whole rock geochemistry in order to constrain the crystallization history of this batholith and its formation conditions. The present work aims to gather the existing data with new data obtained from the Ovejas batholith and La Unión stock, both genetically related to the main intrusion. Gathering our new data with information obtained in previous works, we conclude that the Antioquia batholith was constructed by successive pulses from ca. 97 to 58 Ma in an arc-related setting. The initial pulses are related to syn-collisional tectonics, during the early interaction between the Farallón plate and NW South America. The final pulses, that record Eocene ages, are related to a post-collisional setting, similar to that recorded in other plutons of the Paleogene magmatic arc of the Central Cordillera.

Esta distribución de ambientes permite inferir la extensión hacia el norte de la cordillera marginal al occidente, la cual fue acompañada por el crecimiento de un arco magmático producto de la subducción de la placa del Caribe (Bayona, et al, 2012;Bustamante, et al, 2017). Sin embargo, los detritos llegaron a llanuras extensas y no generaron sistemas fluviales maduros que transportaran sedimentos detríticos gruesos hasta la línea de costa.…”

“…Hacia el oriente, los altos intraplaca tendieron a conectarse y la deformación se extendió más al oriente de los altos preexistentes en el Paleoceno temprano (Bayona, et al, 2012) (Figura 7B). La actividad magmática se incrementó en la Cordillera marginal en el Paleoceno tardío (Cardona, et al, 2011(Cardona, et al, , 2014Bustamante, et al, 2017). Las capas gruesas de cenizas volcánicas al sur de Bogotá (Bayona, et al, 2010) y al nororiente de Perijá (Bayona, et al, 2011) son el indicio de la actividad magmática intraplaca.…”

El norte de los Andes está conformado por varias cadenas montañosas y extensos drenajes que transportan sedimentos a los océanos circundantes. La configuración actual no representa la de los primeros estadios de formación de los Andes del norte. La integración de la información sedimentológica, estratigráfica, geocronológica y de la procedencia de unidades del Coniaciano al Paleoceno expuestas al oriente de la Cordillera Central permite interpretar el cambio en los sistemas de acumulación de ambientes marinos de plataforma a sistemas continentales fluviales y planicies costeras, y establecer la ubicación de los primeros sistemas montañosos y los drenajes que suministraron sedimentos terrígenos a la cuenca. En el Campaniano temprano comenzó la aparición de bloques al occidente sobre la plataforma marina, en tanto que en el Campaniano tardío, emergieron altos intraplaca hacia el oriente, los cuales aumentaron elsuministro de sedimentos terrígenos detríticos al sistema marginal y marino de la cuenca. Los altos intraplaca orientales y el sistema marginal occidental crecieron hacia el norte durante el Maastrichtiano-Paleoceno como producto de los procesos de colisión y acrecentamiento de los bloques alóctonos. Estos levantamientos dieron inicio a varios sistemas de drenaje que cubrieron desde las planicies continentales hasta las marginales adyacentes; sin embargo, la poca capacidad de transporte de sedimentos y la alta tasa de subsidencia favorecieron la acumulación de los sedimentos terrígenos gruesos en canales, planicies y deltas intracontinentales, y solo los sedimentos terrígenos lodosos llegaron a la línea de costa. Esta evolución de los sistemas montañosos y drenajes difiere de lo propuesto por estudios previos que sugieren el crecimiento de altos intraplaca desde el Paleoceno. © 2018. Acad. Colomb. Cienc. Ex.
