Geochemistry and geochronology from Cretaceous magmatic and sedimentary rocks at 6°35′ N, western flank of the Central cordillera (Colombian Andes): Magmatic record of arc growth and collision
TL;DR: In this paper, field relations, U-Pb LA-ICP-MS zircon geochronology from magmatic and sedimentary rocks, and whole-rock geochemistry from volcanic and plutonic rocks are used to reconstruct the Cretaceous arc growth and collision in the awakening of the Northern Andean orogeny in northwestern Colombia.

Cretaceous extensional and compressional tectonics in the Northwestern Andes, prior to the collision with the Caribbean oceanic plateau
S. Zapata,S. Zapata,Agustín Cardona,J. S. Jaramillo,A. M. Patino,Victor A. Valencia,S. Leon,D. Mejia,Andrés Pardo-Trujillo,J.P. Castañeda +9 more
TL;DR: In this paper, the authors integrated field, stratigraphic, sedimentary provenance, whole rock geochemistry, Nd isotopes and U-Pb zircon data to understand the Cretaceous tectonostratigraphic and magmatic record of the Colombian Andes.

The Paleogene arcs of the northern Andes of Colombia and Panama: Insights on plate kinematic implications from new and existing geochemical, geochronological and isotopic data
Agustín Cardona,S. Leon,S. Leon,J. S. Jaramillo,Camilo Montes,Victor A. Valencia,J. Vanegas,Camilo Bustamante,Sebastián Echeverri,Sebastián Echeverri +9 more
TL;DR: In this paper, the cause-effect relations between regional plate kinematics and the spatio-temporal distribution of the circum-Caribbean magmatic arcs are evaluated using whole-rock geochemistry and isotopic constraints.

Sedimentary record of the Cretaceous-Paleocene arc-continent collision in the northwestern Colombian Andes: Insights from stratigraphic and provenance constraints
Andrés Pardo-Trujillo,Agustín Cardona,A.S. Giraldo,S. Leon,S. Leon,D.F. Vallejo,Raúl Trejos-Tamayo,Angelo Plata,J. Ceballos,S. Echeverri,S. Echeverri,Ángel A. Barbosa-Espitia,Ángel A. Barbosa-Espitia,Joshua S. Slattery,Andrés Salazar-Ríos,G.E. Botello,Sergio A. Celis,E. Osorio-Granada,Carlos A. Giraldo-Villegas +18 more
TL;DR: In this paper, the authors present the results of an integrated stratigraphic, paleontological, and provenance study of Upper Cretaceous sedimentary sequences accumulated on the oceanic side, to the west of the collisional event.

Petrogenesis of the late Miocene Combia volcanic complex, northwestern Colombian Andes: Tectonic implication of short term and compositionally heterogeneous arc magmatism
TL;DR: In this article, an integrated field, geochemical, Hf-Nd-Sr isotopic and geochronological study of volcanic arc front rocks of the Combia volcanic complex in the northern segment of the Cauca-Valley (North of 5°N) is presented.
