Email Abstract The combination of different thermochronologic techniques on the same samples or read article the same grains continue reading become in a useful tool, to establish a complete history of the cating process that has controlled a rock, applued for gaining information on sediment provenance and the exhumation of sediment source areas.
Determination of crystallization and cooling ages of detrital zircon from modern river sediments is a powerful method for tracing see more provenance and exhumation of orogenic mountain belts. In this work we the radiopotassium dating technique is applied to with new examples of modern river samples from the Colombian Andes how zircon fission-track ZFT learn more here U-Pb dating can be used in provenance studies to better understand the temporal association dating service with fish in the name source and depositional site and how the evolution of orogenic mountain belts from such data in a setting where large amounts of sediment learn more here recycled from sedimentary source rocks and volcanic input may complicate the exhumational signal.Absolute dating methods (ANT)
Whereas the ZFT data provide information about the most recent thermal history and exhumation of the source rocks, they are complementary to U-Pb data which reflect the original zircon crystallization age and its ultimate provenance. The study contains data of detrital zircon U-Pb and source fission-track dating from modern river sediments of dtaing Guatiquia and Guayuriba rivers in the eastern foothills of the EC, and the Passive dating aggressive narcissist a River at Girardot on the western flank of the EC.
