Even after decades of research and exploration, essential questions about its basin structural arrangement remain unresolved. One of these unsolved problems is the existence of the impact crater’s central uplift, a structure that, if recognized, might improve the understanding of the Sudbury Structure's geological history and its mineral deposit arrangement. Here, we evaluated whether the SS’s South Range could house the Structure’s central uplift. A 3D model of the SS's South Range's central zone using magnetic and structural data is presented here to evaluate the presence of the central uplift within this area. We identified a dome-shaped structure on the model's lower noritic surface, accompanied by a horizontalizing behavior on the model's upper overlaying surfaces. By comparing the observed modeled structural disposition with a conceptual model representing a present central uplift scenario, we propose the presence of this structure in the SS’s South Range's central zone. This consideration might help to clarify Sudbury Structure subsurface rocks disposition relating some of its main magnetic and structural characteristics to the final modeled surfaces' magnetic values and geometrical tendencies.Ítem Agrogeología del silicio : comprensión de los materiales geológicos y la formación de suelos para el fortalecimiento de la agricultura(Universidad EAFIT, 2023) Barrientos Acevedo, Iván Andrés; Hernández Pérez, María IsabelThe characteristics of silicon fertilizers depend on aspects related to their raw materials, manufacturing process, physical presentation and chemical composition. It is evident that the application of silicon in agriculture generates significant benefits for plants by improving their resistance to biotic and abiotic stress, and enhancing the absorption of essential nutrients. These products are primarily derived from inorganic silicates, extracted in their mineral forms and processed to convert them into soluble forms, which, when added to the soil, become silicic acid, a bioavailable source for plants. The stability of silicon fertilizers is a critical aspect, and their effectiveness may vary depending on soil conditions and the type of crop. The edaphological heterogeneity in Colombia, with various soil types and climatic conditions, creates a favorable environment for the cultivation of silicon-accumulating plants, such as rice, sugarcane, corn, wheat, cassava, potatoes, soybeans, and sugar beets. Understanding the mechanisms of silicon absorption and transportation, the appropriate choice of fertilizers, and the edaphological variability in agricultural production are key factors in the effective application of silicon for the benefit of agriculture.Ítem Aguas subterráneas en medio fracturado y su relación con la ocurrencia de movimientos en masa en una ladera del Valle de Aburrá(Universidad EAFIT, 2019) Espinosa Espinosa, César Augusto; Duque Trujillo, José FernandoÍtem Análisis comparativo de la estabilidad del terreno a partir de métodos determinísticos en la cabecera municipal de Armenia, Antioquia(Universidad EAFIT, 2022) Campo Correa, Joel David; Gamboa Ramírez, Marco FidelÍtem Análisis comparativo de la geología estructural en la cuenca Valle Medio del Magdalena por medio de secciones restauradas(Universidad EAFIT, 2023) De Vargas Mendoza, Esteban Darío; Beltrán Triviño, AlejandroÍtem Análisis comparativo de la ocurrencia de Avenidas Torrenciales en el Valle de Aburrá por subcuencas tectónicas(Universidad EAFIT, 2021) Albanés Atehortúa, Dhilan Durley; Osorio Betancur, Juan Pablo; Marín Cerón, Maria Isabel; Noriega Londoño, SantiagoÍtem Análisis comparativo multitemporal de la precipitación entre CHIRPS y estaciones pluviométricas en el desierto de la Tatacoa(Universidad EAFIT, 2022) Cruz Leiva, Daniela; Ramírez Giraldo, Valentina Andrea; Jaramillo Uribe, MarcelaÍtem Análisis de la deformación del segmento norte del Batolito de Ibagué y su relación con el metamorfismo colisional Jurásico de Colombia(Universidad Eafit, 2020) Roncancio Baquero, Juan Sebastian; Bustamante Londoño, CamiloÍtem Análisis de la distribución de tamaño de los cristales de glaucofana en los esquistos azules de Jambaló(Universidad EAFIT, 2020) Camargo Bernales, Juan Sebastián; Bustamante Londoño, CamiloÍtem Análisis de la gestión del riesgo en el Valle de Aburrá a partir de los Planes Municipales de Gestión del Riesgo de Desastres y los Planes de Ordenamiento Territorial(Universidad EAFIT, 2022) Toro Gutiérrez, Pedro; Gamboa Ramírez, Marco FidelThe development in this project was an analysis of the articulation of planning instruments for risk management in the municipalities that make up the Valle de Aburrá metropolitan area was carried out, as well as their inter-municipal relationship to address the risk scenarios that compromise bordering areas, in order to make a matrix with a numerical factor that assesses the most important aspects of each instrument and thus discuss them and draw conclusions, in the analysis process it was observed that some municipalities do not relate their planning instruments to the risk management, are done independently and this causes decision-making to change, this lacks are also observed in inter-municipal risk management, which makes it difficult to reduce and prevent disasters that occur in the territory that compromise two or more municipalities.Ítem Análisis de la producción de artículos científicos de las universidades colombianas(Universidad EAFIT, 2020) Henao Jiménez, Maria Magdalena; Cárdenas Rozo, Andrés LeonardoÍtem Análisis de la relación estructural : geomorfológica por causa del fenómeno de diapirismo de lodo en el Caribe Colombiano : una aproximación(Universidad EAFIT, 2020) Burgos Castaño, Ana María; Duque Trujillo, José FernandoÍtem Análisis de la torrencialidad en las microcuencas de las quebradas La Arenala y El Sesteadero (Itagüi, Antioquia)(Universidad EAFIT, 2022) Ramírez Jaramillo, Claudia Samanta; Sarmiento Contreras, Nicole Stefany; Gamboa Ramírez, Marco Fidel; Marín Cerón, María IsabelÍtem Análisis de las causas del carcavamiento en el Municipio de Briceño, Antioquia(Universidad EAFIT, 2021) Torres Carrasquilla, Verónica; Gamboa Ramírez, Marco FidelÍtem Análisis de las evidencias de migración del magmatismo de arco en el occidente colombiano durante el Cretácico Superior(Universidad EAFIT, 2023) Alzate Giraldo, María Fernanda; Bustamante Londoño, CamiloAlong the Western Cordillera are located rocks of oceanic affinity to the west, and rocks of continental affinity to the east, separated by the Romeral Fault System, as a product of interactions between the Caribbean, Farallon, and South American plates. These rocks present ages ranging from Upper Cretaceous to the Lower Paleogene, implying that the formation of these plutonic igneous bodies occurred simultaneously, originated from two distinct magmatic arcs. The tectonic evolution of this zone is not fully clear yet, as two geological models are proposed where there are two subduction environments of different spatial distribution, due to some authors suggest that both subductions are dipping to the east, while others suggest that one of them is dipping to the west. Rodríguez et al. (2023) propose that, through the study of crystallization ages of igneous bodies in the Western Cordillera, there was a subduction migration event during the Upper Cretaceous, and because of this, they suggest that the distribution of both subductions is towards the east. This study includes analyses that demonstrate that the conditions at this time were not favorable for the occurrence of such event.Ítem Análisis de las unidades geomorfológicas por fotointerpretación y parámetros morfométricos que influyen en la ocurrencia de avenidas torrenciales en la cuenca de la quebrada Naranjal en Quetame, Cundinamarca(Universidad EAFIT, 2024) Agualimpia Perea, María Paula; Valencia Ortiz, Joaquín AndrésNatural disasters associated with torrential floods are considered among the most destructive phenomena in Colombia due to the country’s geological and geomorphological characteristics. This study aims to identify the geomorphological parameters influencing the occurrence of these events in the Naranjal basin, located in Quetame, Cundinamarca. To achieve this, photointerpretation processes were carried out to identify geomorphological units at a scale of 1:10,000, and morphometric parameters of the basin were calculated to analyze the dynamics that generate torrential flood processes. The study revealed that the Naranjal basin is almost entirely dominated by a denudational environment, where intense weathering and erosion processes are facilitated by steep terrain and low drainage capacity. Its elongated shape and morphometric parameters indicate a slow hydrological response, which increases the risk of torrential floods during intense rainfall events.
