Abstract
Este Trabajo de Fin de Grado se basa en el tratamiento, análisis y modelización numérica de las anomalías magnéticas asociadas a la Falla de Messejana-Plasencia en la Península Ibérica occidental, utilizando datos de campo magnético total facilitados por el IGME. EI proceso incluyó la validación y procesamiento de datos, generación de mallas y aplicación de métodos analíticos como la Señal Analítica y la Reducción al Polo. La modelización numérica de las anomalías seleccionadas se llevó a cabo con un modelo de dipolo enterrado, aplicando modelos directo e inverso para calcular la profundidad, el momento magnético y los ángulos de magnetización de las anomalías. Finalmente, los resultados describen las características geofísicas de las estructuras estudiadas, y se comparan con estudios previos de la zona, analizando la viabilidad y las ventajas e inconvenientes del enfoque usado.
This Bachelor's Thesis is based on the processing, analysis, and numerical modelling of magnetic anomalies associated with the Messejana-Plasencia Dyke in the western Iberian Peninsula, using total magnetic field data provided by the IGME. The process included data validation and processing, mesh generation, and the application of analytical methods such as the Analytic Signal and Reduction to the Pole. The numerical modelling of the selected anomalies was carried out using a buried dipole model, applying both forward and inverse models to calculate the depth, magnetic moment, and magnetisation angles of the anomalies. Finally, the results describe the geophysical characteristics of the studied structures and are compared with previous studies of the area, analysing the feasibility as well as the advantages and limitations of the approach used.
