U/Pb detrital zircon provenance from late cretaceous metamorphic units of the Guajira Peninsula, Colombia: Tectonic implications on the collision between the Caribbean arc and the South American margin

Permian to Triassic I to S-type magmatic switch in the northeast Sierra Nevada de Santa Marta and adjacent regions, Colombian Caribbean: Tectonic setting and implications within Pangea paleogeography

“…Geocrhonological results from the latter are discussed by Montes et al (2010). Montes et al (2010) and Weber et al (2010) are also plot. L1 = Lobita Well, C1 = Cicuco-1 Well, C2 = Cicuco-2 Well.…”

“…In this contribution we integrate geologic, zircon U/Pb LAM-ICP-MS and whole rock geochemistry from mylonitized granitoids in the Sierra Nevada de Santa Marta massif with new geochemical data and recently published geochronological data obtained from the adjacent lower Magdalena basin (Montes et al, 2010) and the Guajira Peninsula (Weber et al, 2010) (Fig. 1A and B).…”

A New Early Miocene (Aquitanian) Elasmobranchii Assemblage from the la Guajira Peninsula, Colombia

“…A rapid increase in relative sea level could be explained by an increase in eustatic sea level and/ or an increase in America during the late Oligocene/early Miocene (Weber et al, 2010;Escalona and Mann, 2011;Farris et al, 2011) could also be responsible for this deepening. During the Oligocene-early Miocene, tectonic subsidence increases in western Venezuela (Falcón area) thus extending the Falcón Basin to the south and E-W (Escalona and Mann, 2011).…”

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

“…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).…”

“…10). The docking of the Baja Guajira Basin block to northern South America would have marked the collision between the Caribbean Plate and South American Plate at 71 Ma (Weber et al 2010). This late Cretaceous collision would have involved the ancient Santa Marta range where Cretaceous metasediments crop-out (Weber et al 2010) (Fig.…”
