“…The inception of a Cretaceous passive margin can be taken as a convenient starting point to review the history of landscape development in the Northern Andes. Regionally continuous Cretaceous strata document the persistence of a west-facing oceanic margin (Etayo-Serna, 1994;Moreno-Sanchez and Pardo-Trujillo, 2003), with source areas located to the east, in the Guiana shield (Villamil, 1998;Horton, 2018;Sarmiento-Rojas, 2018). Montes et al (2019) showing significant relief in black, magmatic centers in red, and coarse-grained deposits (stippled pattern), tracking the presence and approximate location of relief, but not its magnitude.…”

A Middle to Late Miocene Trans-Andean Portal: Geologic Record in the Tatacoa Desert

Integration of several geologic lines of evidence reveals the prevalence of a lowland trans-Andean portal communicating western Amazonia and the westernmost Andes from at least middle Miocene until Pliocene times. Volcanism and crustal shortening built up relief in the southernmost Central and Eastern Cordilleras of Colombia, closing this lowland gap. Independent lines of evidence consist first, of field mapping in the Tatacoa Desert with a coverage area of ∼381 km2, 1,165 km of geological contact traces, 164 structural data points, and 3D aerial digital mapping models. This map documents the beginning of southward propagation of the southernmost tip of the Eastern Cordillera’s west-verging, fold-and-thrust belt between ∼12.2 and 13.7 Ma. Second, a compilation of new and published detrital zircon geochronology in middle Miocene strata of the Tatacoa Desert shows three distinctive age populations: middle Miocene, middle Eocene, and Jurassic; the first two sourced west of the Central Cordillera, the latter in the Magdalena Valley. Similar populations with the three distinctive peaks have now been recovered in western Amazonian middle Miocene strata. These observations, along with published molecular and fossil fish data, suggest that by Serravallian times (∼13 Ma), the Northern Andes were separated from the Central Andes at ∼3°N by a fluvial system that flowed into the Amazon Basin through the Tatacoa Desert. This paleogeographic configuration would be similar to a Western Andean, or Marañon Portal. Late Miocene flattening of the subducting Nazca slab caused the eastward migration of the Miocene volcanic arc, so that starting at ∼4 Ma, large composite volcanoes were built up along the axis of today's Central Cordillera, closing this lowland Andean portal and altering the drainage patterns to resemble a modern configuration.

“…The southern boundary of the subducting CAR slab is poorly defined. It has been interpreted as a continuous plate to at least as far south as the Caldas tear at 5°N (Cortes & Angelier, 2005; Kellogg et al., 2019; Pennington, 1981; Van der Hilst & Mann, 1994; Vargas & Mann, 2013; Yarce et al., 2014) or only as far south as the Bucaramanga seismic nest at 7°N (Figure 1) (Chiarabba et al., 2015; Idárraga‐García et al., 2016; Sanchez‐Rojas & Palma, 2014; Syracuse et al., 2016). At Bucaramanga, the relationship between the seismic cluster and plate configurations is also poorly understood.…”

The Caribbean plate subducts beneath northwest South America at a shallow angle due to a large igneous province that added up to 12 km of buoyant crust. The overriding plate lacks volcanism and exhibits Laramide‐style uplifts over 500 km from the trench. Here, we illuminate the subduction structures through finite frequency teleseismic P‐wave tomography and connect those structures to the Laramide‐style deformation on the overriding plate. We use a new data set collected from the Caribbean‐Mérida Andes seismic experiment comprised of 65 temporary broadband stations integrated with permanent stations from the Colombian and Venezuelan national networks. We identify three segments of subducting Caribbean plate with one segment completely detached from the surface. The timing of the detachment aligns with other regional events, including the uplift of the Mérida Andes, about 10 Ma. Slab buoyancy post‐detachment likely resulted in recoupling with the overriding plate, reactivation of Jurassic‐aged rift structures and subsequent uplift of the Mérida Andes. Mantle counterflow over the broken segment induced by rollback of the attached slab likely contributed to the uplift of the Mérida Andes. We conclude that the northern limit of subduction lies south of the Oca‐Ancón fault, though the fault itself may be the surface expression of the boundary. The southern limit of subduction lies south of our study area.

“…Otra zona de compresión se ubica desde el NE de Colombia hasta Costa Rica, conformado por la interacción entre la Placa Caribe, el Bloque de Panamá y el Bloque Norte de los Andes. La Placa Caribe subduce a ambos bloques y además el Bloque de Panamá colisiona activamente con el Bloque Norte de los Andes, provocando un movimiento paralelo sobre el margen continental hacia el Caribe (Kellogg, et al, 2019). Esta interacción genera deformaciones y prismas de acreción, nombradas de este a oeste como el Cinturón Deformado del Caribe Sur (CDCS), Cinturón plegado y fallado de Sinú, y Cinturón Deformado del Norte de Panamá (CDNP), (Giunta, et al, 1996;Cerón, 2008).…”
