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 Aquifer eustacy explains sedimentary cycles in a tropical epicontinental sea during a greenhouse world : a case of study of the Turonian the La Luna Formation(Universidad EAFIT, 2022) Restrepo Penagos, Jimena; Beltrán Triviño, Alejandro; Rodríguez Trejo, Alejandro; Paez Reyes, ManuelÍtem Arquitectura estructural, estratigráfica y sedimentológica a partir de la interpretación de imágenes de resistividad (AFR) del Grupo Honda (Mioceno) en el pozo Dina K-R, Valle Superior del Magdalena(Universidad EAFIT, 2019) Gómez Ramírez, Valentina; Beltrán, AlejandroÍtem Caracterización litológica área norte de Campo Diamante Cementos Argos S.A. - Municipio de Sonsón(Universidad EAFIT, 2020) Zota Balvin, Mario Alejandro; Osorio Castrillón, Emilio José; Duque Trujillo, José FernandoÍtem Caracterización litológica de los acantilados de Juanchaco – Ladrilleros, Valle del Cauca, mediante la tecnología de escáner láser terrestre(Universidad EAFIT, 2019) Castro Ramírez, Karla Vanessa; Beltrán Trivillo, Alejandro Iván; Paniagua, Juan Felipe; Ricuarte Villota, ConstanzaÍtem Caracterización petroquímica del deposito VMS en la Mina el Roble(Universidad EAFIT, 2021) Plata Otero, Pedro Jose; Monroy Reyes, Diego Alejandro; Marín Cerón, María IsabelÍtem Caracterización petroquímica y análisis de susceptibilidad magnética de las calititas propuestas como "tectitas" en la subcuenca Cauca, Colombia(Universidad EAFIT, 2022) Barrera Jaramillo, Luz Marina; Sánchez Acosta, Juanita; Marín Cerón, María IsabelÍtem Causas de las avenidas torrenciales e inundaciones rápidas en el Departamento del Huila en los municipios de Algeciras, Campoalegre, Neiva y Rivera en febrero del 2017(Universidad EAFIT, 2019) Méndez Hernández, Leonardo; Manchego Acevedo, Sebastián; Gamboa Ramírez, Marco FidelÍtem Contexto tectónico durante la acumulación de las formaciones Amagá y Combia (Mioceno tardío) en el suroccidente antioqueño – sección de la quebrada La Táparo, a partir de análisis de proveniencia sedimentaria(Universidad EAFIT, 2019) Diáz Navarro, Maria Kamila; Monsalve Martínez, Jorge Luis; Beltrán Trivillo, Alejandro Iván; Duque Trujillo, José FernandoÍtem Contribución a la paleogeografía del Devónico-Carbonífero de la Cordillera Oriental de los Andes Colombianos : una comparación de la mineralogía cuantitativa de las coberteras sedimentarias paleozoicas de los macizos de Quetame y Floresta(Universidad EAFIT, 2021) Palacios Torres, Juliana; Beltrán Triviño, Alejandro IvánThis work presents new mineralogical and geochemical data of the Precambrian basements and the Paleozoic sedimentary coverts of the Quetame and Floresta massifs in the Eastern Cordillera of the Colombian Andes. The mineralogical and geochemical analyses by X-ray´s diffraction and fluorescence reveal that the sedimentary contributions for the areas of the Quetame (Cundinamarca and Meta) and Floresta (Boyacá) massifs had the same origin during the Paleozoic: the Guyana Shield. The mineralogical differences between the - 6 - sedimentary covers are due to differences in the accumulation environments due to their differential positions with respect to the coastline. Our findings allow us to infer that during the Middle Devonian the area of the Quetame Massif was in a position closer to the continent (Areniscas de Gutiérrez Fm) than the area of the Floresta Massif, which was found in deeper marine sedimentary environments (El Tíbet and Floresta formations). In the early Carboniferous, the positions are reversed with respect to the coastline, the area of the Floresta Massif was closer to the mainland (Cuche Fm) while the area of the Quetame Massif was in a deeper position represented by the Capas Rojas del Guatiquía Fm.Ítem Definición de elementos sedimentológicos, estratigráficos y estructurales de la Formación Ciénaga de Oro (Oligoceno-Mioceno temprano, pozo Bonga-1, Valle Inferior del Magdalena), a partir de la interpretación de imágenes microresistivas(Universidad EAFIT, 2020) Giraldo Gómez, Javier Alejandro; Duque, Helman; Beltrán, AlejandroÍtem Definición de escenarios de lahares en el volcán de Colima y análisis de susceptibilidad a inundación en la población de San Marcos, Jalisco, México(Universidad EAFIT, 2020) Pérez Hernández, Andrea; Pérez Mejía, Natalia Andrea; Capra Pedol, Lucia; Duque Trujillo, Jose FernandoLahars are a mixture of water and sediments associated with volcanic processes, they can be generated by different factors such as melting glaciers, dam’s ruptures and heavy rainfall; this last factor occurs frequently in volcanoes, where rainfall/runoff process enhance erosion on main channels generating lahars that can reach large distances from their source, causing damages on the infrastructure of surrounding populations. The present work presents rain-triggered lahar susceptibility analysis along La Arena ravine and the effect on San Marcos; a village located 14 kilometers southeast of the Colima Volcano, in Mexico, between the limits of the states of Jalisco and Colima. To define the inundation limits, the program FLO-2D was chosen to model lahars, through data of rainfall events in 2018 and 2019. Using this information, a rainfall analysis was conducted and it was possible to identify those associated with the generation of lahars and to identify different scenarios depending on the total rainfall accumulation and its maximum intensity. Three different scenarios (small, intermediate and large) were identified and simulated with the FLO-2D code to analyze the effect on the population of San Marcos. Based on the numeric simulations hazard maps were made, which were used as a tool to study and analyze the area exposed of lahar inundation, considering that the three scenarios can generate an impact to the infrastructure. Aditionally, the study zone can be affected due to events of great magnitude, such as rainfall produced by hurricane events. Likewise, a probabilistic analysis was also conducted; where the large scenario presents low probability of occurrence, since these are events with regional (hurricane) character than those for the intermediate and small scenarios (rainy season). Through the analysis of the maps here presented, the population of San Marcos presents a low-medium hazard level to floods caused by lahars.Ítem 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 ¿Es el Escudo de Guyana la principal fuente de aporte sedimentario a la cuenca del VMM durante el intervalo Cretácico-Neógeno? implicaciones en la paleogeografía y el levantamiento de los Andes colombianos(Universidad EAFIT, 2020) Rodríguez Caicedo, Angie Karolain; Duque Carrillo, Daniel Andrés; Beltrán Triviño, AlejandroDifferent tectonic processes are acting over the northern margin over the Andean Cordillera, where both the subduction of the Nazca plate, as well as the compression processes that gave rise of the tectonic inversion of the Easter Cordillera in Colombia can be highlighted. In areas like the Middle Magdalena Valley, this inversion generated several changes in the sediments accumulation system, changes that can be identify by provenance analysis. In this project the provenance analysis of Olini Group, Set Ti, Ti2 and Mesa Formation was obtain, which the outcrops are between the Middle Magdalena Valley and the western flank of the Eastern Cordillera, between the departmental limits of Boyacá and Santander. These analyzes indicates that the main areas of contribution of these formations are possibly the Central Cordillera and the Guyana Shield, but due to the high tectonic activity that occurs at the end of the Cretaceous and during the Cenozoic, sediment reworking occurred on the easter margin of Colombia associated with the uplift of the Eastern Cordillera.Ítem Estudios magnéticos de sedimentos marinos de las bahías de Cartagena y Barbacoas (Colombia); evidencias del aporte de sedimentos del río Magdalena a zonas arrecifales(Universidad EAFIT, 2015) Mejía Echeverry, Daniela; Duque Trujillo, José Fernando; Chaparro, Marcos Adrián EduardoÍtem Evaluación de los efectos del óptimo climático del Eoceno temprano sobre los sedimentos de la formación arcillas de Socha a partir de una sección estratigráfica en el municipio de Güicán, Boyacá(Universidad EAFIT, 2019) Gómez Marulanda, Sebastián; Cárdenas Rozo, Andrés Leonardo
