Ítem 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 Análisis hidrogeoquímico y de calidad del agua subterránea en el Valle de San Nicolás - Oriente antioqueño, para su uso potencial en abastecimiento poblacional(Universidad EAFIT, 2021) Giraldo Ulloa, Vanessa; Jaramillo Uribe, MarcelaThe population increase in eastern Antioquia has triggered a series of negative consequences in the supply of public services, particularly the water resource, due to its overexploitation for various uses, climate change and pollutants due to anthropic activities. Based on these statements, groundwater is seen as an alternative source of supply, for which it is necessary to identify various factors, including the performance of hydrogeochemical and quality analysis of this water, to determine whether or not is suitable for human consumption. This document presents the analyses mentioned above for the San Nicolás Valley, with the purpose of identifying the main contaminants for groundwater and determining the sufficiency in quality to be used as a source of supply, through the calculation of the ionic balance, Piper, Stiff and Stabler diagrams, and comparisons with the Colombian regulations related to the characteristics that water must have in order to determine its use.Ítem Aplicación del método de anisotropía de susceptibilidad magnética en neotectónica : caso de estudio Valle de Aburrá y alrededores(Universidad EAFIT, 2020) Jaraba Fernández, Duvan Alejandro; Ruiz Suta, Maria Paula; Marín Cerón, Maria Isabel; Noriega Londoño, SantiagoMagnetic susceptibility anisotropy (ASM) is a method that allows characterizing the magnetic factory of rocks and sediments, and this in turn serves to estimate the type of tectonic deformation generated by a stress field. In the zone of influence of an active fault, the magnetic factory allows to measure the tectonic deformation associated with the displacement of said structure, in addition, if this deformation is printed in quaternary deposits, it is possible to estimate the geometry and kinematics of these faults and contribute to the neotectonic knowledge of a region. This work explores the application of ASM techniques on deformed quaternary deposits that cover active faults with the aim of providing information about the geometry and kinematics of faults with recent displacements in the eastern and western edge of the Aburrá Valley, where they have been reported neotectonic sites of interest. The results obtained suggest that there is a relationship in deformation for both sides of the Aburrá Valley due to the similarities in the maximum and minimum stresses and the anisotropy present at each point of interest. Finally, it is concluded that the application of ASM in sediments deformed by active faults provides fundamental information for the calibration of the models of tectonic evolution and the evaluation of the seismic threat in the metropolitan area of the Valle de Aburrá and its neighboring sectorsÍtem Características petrográficas y de alteración hidrotermal en litotipos asociados a sistemas epitermales de baja sulfuración, estudio caso mina la Reliquia (Antioquia - Colombia)(Universidad EAFIT, 2022) Herrera Ospina, Mateo; Gómez Gutiérrez, Diego FelipeThe porphyrite systems are in relation to what are the continental arcs and are located at what they are between 2 and 5 km deep. Low, intermediate, and high sulphidation epithermal deposits are associated with hydrothermal magmatic environments. Being in contact with meteoric water near the surface forms what these types of deposits are. The hydrothermal alterations in the study area are related to the potassium and argillic alteration where the potassium alteration is directly related to the porphytic systems belonging to what is the Segovia Batholith and the argillic alteration belongs to what is the quartz-gold veins of the La Reliquia mine. The mine 'La Reliquia' is framed in what is known as the Segovia – Remedios Mining District (DMSR), where gold mineralizations related to intrusive bodies (Segovia Batholith) have been identified in this case associated with the Central Mountain Range and unidentified mineralizations within them. Many of these mineralizations present in the Segovia Batholith are located in what belongs to the reverse fault system of the DMSR.Ítem Cuantificación de la geodiversidad como estrategia de apropiación social : caso de estudio, Valle de Aburrá(Universidad EAFIT, 2020) Restrepo Marín, Luisa María; Marín Cerón, María IsabelÍtem 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 Propuesta de clasificación de los organales en el Departamento de Antioquia, Colombia(Universidad EAFIT, 2020) Cano Alzate, Eliana María; Rentería Cárdenas, María Camila; Gamboa Ramírez, Marco Fidel
