The Magdalena River basin, located on the Colombian Andes, is the most important basin in the country, with an area of 257,400 km2 and altitudes between 0 to 5,670 m. The basin is characterized by having a huge variety of lithological units along an abrupt topography and intense processes of erosion and transport, generating recent sediments with a high concentration of minerals. In the present work, the heavy minerals of 21 recent sand samples from channel bars of the Magdalena River and different first and second order tributary drainages towards the east and west of the basin were analyzed. Drainage from the Central and Western Cordillera are characterized by abundant and well-preserved unstable minerals such as olivine, pyroxene, amphib...
