Ítem ¿Cómo rastrear la vida en la tierra?(2016-03-11) Cárdenas, Andrés Leonardo; Martínez, José Ignacio; González Cotes, Ana María; Arango Uribe, María Adelaida; Londoño Rivera, Ana María; Cárdenas, Andrés Leonardo; Martínez, José Ignacio; González Cotes, Ana María; Arango Uribe, María Adelaida; Londoño Rivera, Ana MaríaÍtem Estudio paleomagnético en rocas terciarias de la cuenca del Rio Cauca, departamento de Caldas : implicaciones tectónicas(Universidad EAFIT, 1995) Sierra L., Gloria; Estrada, Juan; Macdonald, William; Universidad EAFIT; Ingeominas; State University of New YorkÍtem Provenance analysis for the Oligocene-Early Miocene Cienaga de Oro Formation at a stratigraphic section between Monteria and Planeta Rica(Universidad EAFIT, 2018) Manco Garcés, Alejandra; Sánchez Plazas, Carlos Javier; Marín Cerón, María IsabelWe study a stratigraphic section in the San Jacinto fold and thrust belt located between Monteria and Planeta Rica towns. This section displays part of the Oligocene-Early Miocene Ciénaga de Oro Formation (COF). This work analyses the sediments provenance by using a multi-tool approach throughout: (I) conglomerate and sandstone counting clast with mesh, (II) heavy minerals analysis, and (III) paleocurrent analysis. Our results suggest a deltaic to transitional environment deposition, as it has been proposed by previous authors. Two main sources have been identified from a dissected arc province: a granitic to pegmatitic main source and a basic igneous secondary source rock, located to the east and southwest of the current position. Therefore, we propose the Central Cordillera as the main source area to the COF.
