“…Recent paleomagnetic studies [ Bayona et al , 2006, 2010] have shown that Jurassic rocks exposed in the southern border of the Sierra Nevada Province displaced northward (from 9°S to 4°N) with respect to cratonic South America, and rotated clockwise (17° ± 13°C) between the Middle‐Late Jurassic and Early Cretaceous. This rotational event may have occurred during the opening of the Early Cretaceous Colombian marginal back‐arc basin [ Pindell , 1993].…”

“…This rotational event may have occurred during the opening of the Early Cretaceous Colombian marginal back‐arc basin [ Pindell , 1993]. Bayona et al [2010] report that the pre‐Early Cretaceous units of the SNSM were at their current latitude by the Albian. Vertical axis clockwise rotation of up to 30°C during the Cenozoic has been proposed to accommodate simultaneous contractional and extensional deformation in the Cesar and Lower Magdalena basins [ Montes et al , 2010].…”

Vertical tectonics at a continental crust‐oceanic plateau plate boundary zone: Fission track thermochronology of the Sierra Nevada de Santa Marta, Colombia

et al. 2011

The topographically prominent Sierra Nevada de Santa Marta forms part of a faulted block of continental crust located along the northern boundary of the South American Plate, hosts the highest elevation in the world (∼5.75 km) whose local base is at sea level, and juxtaposes oceanic plateau rocks of the Caribbean Plate. Quantification of the amount and timing of exhumation constrains interpretations of the history of the plate boundary, and the driving forces of rock uplift along the active margin. The Sierra Nevada Province of the southernmost Sierra Nevada de Santa Marta exhumed at elevated rates (≥0.2 Km/My) during 65–58 Ma in response to the collision of the Caribbean Plateau with northwestern South America. A second pulse of exhumation (≥0.32 Km/My) during 50–40 Ma was driven by underthrusting of the Caribbean Plate beneath northern South America. Subsequent exhumation at 40–25 Ma (≥0.15 Km/My) is recorded proximal to the Santa Marta-Bucaramanga Fault. More northerly regions of the Sierra Nevada Province exhumed rapidly during 26–29 Ma (∼0.7 Km/My). Further northward, the Santa Marta Province exhumed at elevated rates during 30–25 Ma and 25–16 Ma. The highest exhumation rates within the Sierra Nevada de Santa Marta progressed toward the northwest via the propagation of NW verging thrusts. Exhumation is not recorded after ∼16 Ma, which is unexpected given the high elevation and high erosive power of the climate, implying that rock and surface uplift that gave rise to the current topography was very recent (i.e., ≤1 Ma?), and there has been insufficient time to expose the fossil apatite partial annealing zone

“…This structural complexity reflects several episodes of Mezo-Cenozoic oceanic terrane accretion, continental arc growth and strike translation of paraautochthonous continental terranes (Bayona et al, 2006;Bayona et al, 2010;Escalona and Mann, 2010;Montes et al, 2010;Pindell et al, 1998;Pindell et al, 2005;Spikings et al, 2014;Spikings et al, 2005;Toussaint and Restrepo, 1996;Villagómez et al, 2011;Villagómez and Spikings, 2013).…”

Paleomagnetism and magnetic fabric of the Eastern Cordillera of Colombia: Evidence for oblique convergence and nonrotational reactivation of a Mesozoic intracontinental rift

We report the paleomagnetic and magnetic fabric results of 58 sites from Cretaceous-Miocene marine and continental strata from the Eastern Cordillera (EC) and the Cucuta zone, at the junction between the Santander Massif and the Merida Andes of Colombia. The EC is an intracontinental doubly vergent range inverting a Triassic to Early Cretaceous rift zone. Twenty-three sites reveal nonsystematic tectonic rotations, including unrotated areas of the EC range with respect to stable South America. Our data show that the EC inverted a NNE oriented rift zone and that the orientation of the Mesozoic rift and the mountain chain roughly correspond. Interestingly, magnetic lineations from anisotropy of magnetic susceptibility analysis do not trend parallel to the chain but rather are oblique to the main orogenic trend. By also considering GPS evidence of a~1 cm/yr ENE displacement of central western Colombia accommodated by the EC, we suggest that the Miocene-Recent deformation event of this belt arises from ENE oblique convergence reactivating a NNE oriented rift zone. Oblique shortening was likely partitioned into pure dip-slip shear characterizing thick-skinned frontal thrust sheets (well known along both chain fronts) and by range-parallel right-lateral strike-slip faults, which have not been identified yet, but likely exist in the axial part of the EC. Finally, the 35°± 9°clockwise rotation observed in four post-Miocene magnetically overprinted sites from the Cucuta zone reflects late Cenozoic and ongoing right-lateral strike-slip displacement occurring along faults parallel to the Boconó fault system, possibly connected with the right-lateral faults inferred to exist along the axial part of the EC.
