There was an analysis and modeling of public Regional Gravity and Magnetic data of the area, in order to investigate and understand the geometry and depth extent of the Wawa Greenstone Belt.The Michipicoten (Wawa) Greenstone Belt (MGB) is an Archean-age greenstone belt located east-northeast of Lake Superior, in the Superior Province of Canada. It is a supracrustal sequence situated in the Wawa-Abitibi terrane, where numerous mineral exploration initiatives had been made due to its potential mineral deposits. Despite the extensive exploration and mining activities in the region, comprehensive geophysical and geological investigations to determine the belt's subsurface structures and possibly mineralization patterns are limited. This project aims to conduct a detailed analysis and modeling of publicly available regional gravity and aeromagnetic datasets of the MGB, in order to explore the subsurface geometry and potential mineralization zone within the belt. The datasets obtained from the Geoscience Data Repository for Geophysical Data, a Canadian National Database, were modeled with the educational edition of the Oasis montaj software, using the GM-SYS extension of the 2022.2 (20221207.28) software version. The project involved the construction of four 2.5D forward gravity models, along transverse and longitudinal sections, relative to the identified geological structures. These models were then used to interpret the subsurface geological framework, focusing on key formations and structures such as the Hawk, Wawa, and Catfish Lake assemblages, along with significant fault zones. The aeromagnetic data were analyzed qualitatively in two maps, one was the Residual Magnetic Total (RTM) field of the MGB and the second one was its First Vertical Derivate, comparing them with the geological context. The gravity data processing and modeling results offer a comprehensive insight into the distribution and origins of the gravity anomalies within the upper crust of the MGB. The most significant outcome of the study is that after modeling the gravity datasets, the models revealed a characteristic Archean keel-and-dome pattern formed by the MGB and its associated tonalite-granodiorite plutons, both in terms of intrusion and surrounding geometry.El “Michipicoten Greenstone Belt (MGB)” es un cinturón de rocas verdes de la era Arcaica ubicado al este-noreste del Lago Superior, en la Provincia Superior de Canadá. Es una secuencia supracrustal situada en el terreno Wawa-Abitibi, donde se han realizado numerosas iniciativas de exploración mineral debido a su potencial de yacimientos minerales. A pesar de las extensas actividades de exploración y minería en la región, las investigaciones geofísicas y geológicas integrales para determinar las estructuras subsuperficiales del cinturón y posibles patrones de mineralización son limitadas. Este proyecto tiene como objetivo realizar un análisis detallado y modelado de conjuntos de datos regionales de gravedad y aeromagnetismo públicamente disponibles del MGB, para explorar la geometría subsuperficial y la zona de mineralización potencial dentro del cinturón. Los conjuntos de datos obtenidos del “Geoscience Data Repository for Geophysical Data”,, una base de datos nacional canadiense, fueron modelados con la edición educativa del software Oasis montaj, utilizando la extensión GM-SYS en la versión del software 2022.2 (20221207.28). El proyecto implicó la construcción de cuatro modelos de gravedad adelante 2.5D, a lo largo de secciones transversales y longitudinales, en relación con las estructuras geológicas identificadas. Estos modelos se utilizaron para interpretar el marco geológico subsuperficial, enfocándose en formaciones y estructuras clave como los conjuntos de Hawk, Wawa y Catfish Lake, junto con zonas de falla significativas. Los datos aeromagnéticos fueron analizados cualitativamente en dos mapas, uno era el campo magnético total residual (RTM) del MGB y el segundo su primera derivada vertical, comparándolos con el contexto geológico. El procesamiento de datos de gravedad y los resultados del modelado ofrecen una visión integral de la distribución y los orígenes de las anomalías de gravedad dentro de la corteza superior del MGB. El resultado más significativo del estudio es que, después de modelar los conjuntos de datos de gravedad, los modelos revelaron un patrón característico de manto y cúpula del Arcaico formado por el MGB y sus plutones asociados de tonalita-granodiorita, tanto en términos de intrusión como de geometría circundante.GeocientíficoPregrado40 páginasapplication/pdfengUniversidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geocienciashttps://repositorio.uniandes.edu.co/static/pdf/aceptacion_uso_es.pdfinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Analysis and interpretation of regional geophysical data in the Michipicoten (Wawa) Greenstone Belt, Superior Province in CanadaAnálisis e interpretación de datos geofísicos regionales en el Greenstone Belt de Michipicoten (Wawa), Provincia Superior de CanadáTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_7a1fTexthttp://purl.org/redcol/resource_type/TPSuperior Province (Canada)Geophysical modelingTransectsArchean Greenstone BeltForward gravity model2.5 D profileAeromagneticGravityGM-SYS extensionOasis montajBouguer anomalyGeocienciasAlamos Gold Inc.
