Ítem Análisis de sensibilidad en el diseño de parámetros de adquisición sísmica 3D3C para el Campo Tenerife(Universidad EAFIT, 2010) Duarte Castro, María Teresa; Andrés E., Calle; Guevara, Saúl E.Ítem Aporte al conocimiento de la geología volcánica en las inmediaciones de la población de Río Blanco (Cauca)(Universidad EAFIT, 2011) Téllez Arjona, Laura; Toro Villegas, Gloria ElenaIn the western flank of the volcano Sotará, in the vicinity of the population of Rio Blanco, we identified eleven units of volcanic origin. While the observation Window is limited to deposits located in the middle of the volcano, western flank, characteristics petrographics and stratigraphic relationships to define at least two possible stages of evolution in the magma chamber. These steps would relate topossible processes of recharge and magmatic differentiation which are evident. Although complete information is needed to raise an evolutionary history of volcanism of volcano Sotará, here arises a hypothesis about the evolution of the study based on stratigraphic, petrographic and geochemical volcanic deposits located in the Rio Blanco area, that must be confronted with future.Ítem Datación por fotoluminiscencia de algunas formaciones superficiales del Llano de Ovejas, Cordillera Central, Antioquia(Universidad EAFIT, 2007) García Londoño, Carolina; Hermelin Arbaux, MichelPhotoluminescence method allows the determination of the age of burial of materials with a range from 6 to 800 000 years under optimal conditions; the method is really important for the study of diverse quaternary formations. This work marks the first application of Photoluminescence (OSL- Optical Stimulated Luminescence) in Colombia. The objective is to contribute with the development of new dating techniques applied to Quaternary, and to create the Photoluminescence Laboratory at University EAFIT. At these laboratory samples were prepared and then shipped to Canada for dating at the AGE Laboratory of McMaster University in Canada.Ítem Estratigrafía, petrología y geoquímica de las rocas volcánicas del flanco occidental del volcán Puracé, alrededores de Coconuco(Universidad EAFIT, 2009) López Castro, Sandra Milena; Toro Villegas, Gloria ElenaThe cartographic and allostratigraphic analysis of volcanic rock outcrops surrounding the Coconuco municipality gather new data which expands the knowledge of volcanism in southwestern Colombia. The cartography of 10 allostratigraphic and 11 geomorphologic units allowed to define a general allostratigraphic column for the region in order to describe the intercalation and interdigitation of lava flow deposits and pyroclastic deposits associated with the Coconucos volcanic chain, located in the western flank of the Puracé Volcano between 2400 and 3200 masl.Ítem Uso de sísmica pasiva en superficie y su relación con la anisotropía y producción de fluidos en yacimientos del piedemonte llanero colombiano(Universidad EAFIT, 2010) Maldonado Cano, Eliana María; Ortiz, Alberto; Agudelo, William
