Compositional and provenance changes of paleocene sandstones in the eastern cordillera and western side of the Maracaibo block

In the eastern cordillera of Colombia and western of Maracaibo block, paleocene sandy units show significant compositional and provenance differences, suggesting either changes in the tectonic regimen in the source areas or in depositional conditions. Lower paleocene units show a decrease of total l...
