Ítem Assessing the geodiversity, morphometrical diversity and sensitivity index in Nuquí – Chocó associated with human activities(Universidad EAFIT, 2024) Ramírez Calderón, Miguel Ángel; Marín Cerón, María IsabelÍtem Structural Controls on Geothermal Systems along the Northern Andes of Colombia : An Integrated Remote Sensing Analysis of the Dabeiba and Sibundoy Valley Geothermal Fields(Universidad EAFIT, 2024) Montoya Londoño, Nicolás; Marín Cerón, María IsabelThis study employs a combination of remote sensing techniques and geothermal analysis to investigate the structural and thermal characteristics of two geothermal systems in Colombia. By utilizing Mark's proposal (1992) for delimitating lineaments, and Principal Component Analysis (PCA) for generating shadow models, the research highlights regional and local structural features that are closely associated with geological structures. Fault systems and lineaments emerge as crucial elements influencing subsurface fluid flow, heat transfer, and the development of geothermal reservoirs. The integration of remote sensing data with advanced structural analysis techniques reveals significant factors shaping geothermal dynamics in the region. These findings emphasize the necessity of considering structural controls in the exploration and sustainable management of geothermal resources. The study focuses on the Dabeiba Geothermal System (DGS), potentially linked to a Miocene extensional event, emphasizing the role of fault structures, especially in the Guineales Formation, as conduits for fluid flow and heat migration from deep sources. The complex structural zones with different degrees of deformation and fracture densities directly influence the advection of the isotherms near the Dabeiba-Pueblo Rico suture zone. This geothermal play system is dominated by fault-controlled non-magmatic convection, where convection occurs predominantly along fault lines and is accompanied by meteoric water infiltration along their traces. The Sibundoy Valley Geothermal System (SVGS) as a typical example of a mixed geothermal system, where heat originates from a young magmatic source but is mainly controlled by deep faults within a pull-apart basin. These faults not only influence the distribution of monogenetic volcanoes but also shape the spatial arrangement of hydrothermal springs. The interaction between geological structures and fluid flow patterns highlights the complexity of geothermal systems. Furthermore, the presence of partial crystallizations and unique caldera geometries leads to the formation of seal layers or condensate layers, redirecting both meteoric water recharge fluxes and volcanic heat fluxes, significantly impacting hydrogeological and geothermal dynamics. This research contributes valuable insights for the geoscientific and energy exploration communities, informing decision-making processes for the assessment and development of geothermal resources.Ítem Modelos 1D y 2D en la cuenca Caguán-Putumayo de Colombia : implicaciones para la generación de hidrocarburos líquidos en la cuenca(Universidad EAFIT, 2023) Redondo Toro, Laura; Betrán Triviño, Alejandro; Páez Reyes, Manuel; Aguilera, RobertoÍtem Tectonic Control On Costal Subsidence Around Cartagena Area And Northwestern Colombian Caribbean Coast(Universidad EAFIT, 2023) Gómez Álvarez, José Daniel; Duque Trujillo, José FernandoÍtem Advances and findings in geodiversity estimation with an emphasis on the potential of geosystem goods and services : Sierra Nevada de Santa Marta(Universidad EAFIT, 2023) Zapata Herrera, Juan Fernando; Marín Cerón, María IsabelÍtem Estimation of potential groundwater recharge, and evaluation of the possible effects of climate change scenarios on recharge in La Tatacoa desert(Universidad EAFIT, 2023) Ballesteros Buitrago, Karen Dayana; Jaramillo Uribe, Marcela; Vergara Bechara, SantiagoÍtem Clasificación de puntos de agua mediante análisis hidroquímico y métodos de estadística multivariada en un sistema hidrogeológico dominado por rocas ígneas plutónicas y depósitos de vertiente(Universidad EAFIT, 2022) Chavarria Arboleda, Laura; Jaramillo Uribe, MarcelaÍtem Elaboración de un catálogo de bacterias cultivables como línea base de aislamientos con potencial hidrocarbonoclasta, de dos zonas con alta influencia petrolífera en Colombia(Universidad EAFIT, 2022) Enríquez Delgado, Sandra Milena; Pinel Peláez, NicolásFrom suspensions of environmental substrates (water, soil and sediment) from two zones with high oil influence in the country (Magdalena and Casanare) were isolated through conventional cultivation, 200 strains that formed the baseline of a catalog of bacterial biological interpretation. In this study, emphasis was placed on the cultivation process, isolation and integral identification (morphological, biochemical and genetic) of the isolates, with a view to understanding the repertoire and its functional dynamics. Molecular identification is based on genomic analysis from DNA sequencing and direct amplification of the 16s gene rRNA from bacterial biomass. Additionally, through the use of a minimal medium of salts supplemented with hydrocarbons at 1% v/v as the only carbon source, 27 were identified strains with hydrocarbonoclastic potential. The strains identified as tolerant to crude and bacterial consortia inoculated from soil samples directly, were tested of biodegradation, evaluating the percentage transformation of total hydrocarbons of oil (HTP) in 30 days of incubation. The biodegradation rates of HTP were determined under gas chromatography analysis coupled to a flame ionization detector (GCFID) and were related to the growth kinetics (CFU/mL) of the isolates through of the incubation time (30 days). Under observation time and post-identification molecular biodegradation of the isolates members of genera such as: Bacillus, Pseudomonas, Enterobacter and Burkholderia-Caballeronia-Paraburkholderia, in a range between 53.66 and 82% and in one of the consortiums 91.28%. The strains evaluated demonstrated an important enzymatic potential to degrade hydrocarbons and provide the opportunity to continue with the study of the bioremediation potential in areas affected by hydrocarbon contamination.Ítem Middle Miocene Distributive Fluvial System : Cerbatana Conglomerate Beds (Honda Group, Tatacoa Desert, Colombia)(Universidad EAFIT, 2022) Romero Montes, Elizabeth; Cárdenas Rozo, Andrés LeonardoÍtem Geochemistry and geochronology of the Permian arc magmatism of the Central Cordillera of Colombia(Universidad EAFIT, 2022) Restrepo Velásquez, Marcela; Bustamante Londoño, CamiloÍtem Regional tectonic constraint through low-temperature thermochronology : The Don Javier porphyritic system, southern Peru(Universidad EAFIT, 2021) Chuquimia Pacheco, Gino Enmio; Marín Cerón, María IsabelÍtem Fossil-Lagerstätte La Venta (middle Miocene, Northern South America): Paleoecological signatures of the fossil mammalian assemblage of the Honda Group(Universidad EAFIT, 2019) Mora Rojas, Laura; Cárdenas Rozo, Andrés LeonardoÍtem Wave Energy Flux Variability Along Continental Shelves of Compressional Margins : a Wave Climate Data-Driven Approach(Universidad EAFIT, 2021) Ramos-Chavarriaga, Esteban; Paniagua-Arroyave, Juan FelipeDominant dynamics of available wave energy dictate coastal gradients in alongshore sediment transport on continental shelves, where large-scale coastal features depend upon wave-induced sediment fluxes. We propose to study wave energy flux (P) variability from high-fidelity simulations of wave climate data, to classify the fundamental patterns of P into morphodynamical regimes, serving as a data-driven indicator for large-scale, and wave-induced coastal evolution. Additionally, we describe the variability of P in a complex system framework to produce a reduced-order model (ROM) of the system of interest. Where we discover, reduce, and solve a symbolic expression that forecasts the spatial variability of P along continental shelves, balancing accuracy, and complexity to obtain a parsimonious model of reality.Ítem Fossil-lagerstatte La Venta (middle miocene, Northern South America) : paleoecological signatures of the fossil mammalian assemblage of the Honda group(Universidad EAFIT, 2019) Mora Rojas, Laura; Cárdenas Rozo, Andrés LeonardoÍtem Scaling hydraulic conductivity by applying laplacian with skin to fractures network(Universidad EAFIT, 2021) Cetre Orejuela, Harol Alexander; Jaramillo Uribe, Marcela; Álvarez Villa, Oscar DavidÍtem Análisis hidroestructural y estimación de recarga potencial por precipitación de la dunita de Medellín, sistema acuífero del valle de Aburrá(Universidad EAFIT, 2021) Patiño Rojas, Sandra Maria; Jaramillo Uribe, MarcelaÍtem Dinámica costera durante el Mioceno tardío - Plioceno temprano al norte del Cinturón Plegado Sinú - San Jacinto, Colombia(Universidad EAFIT, 2021) Cárdenas Gómez, Claudia Patricia; Cárdenas Rozo, Andrés Leonardo; Rincón Martínez, Daniel AndrésÍtem Evaluación de métodos heurísticos y estadísticos para zonificación de amenazas por movimientos en masa a escalas intermedias(Universidad EAFIT, 2021) Gamboa Ramírez, Marco Fidel; Bedoya Sanmiguel, Oscar GeovanyÍtem Caracterización morfo-química y diferenciación del material particulado PM10-2.5 en el Valle de Aburrá (Medellín, Colombia)(Universidad EAFIT, 2020) Rausch, Juanita; Jaramillo Vogel, David; Avellaneda Franco, José David; Duque Trujillo, José FernandoÍtem Jurassic to early Cretaceous crustal thickness in the Colombian Northern Andes : insight on the magmatic thermal variations and emplacement conditions of plutonic rocks(Universidad Eafit, 2020) Chavarría Chavarría, Luisa Fernanda; Bustamante Londoño, Camilo
