I completed a B.Sc. Degree in Geology at the University of Salamanca in 2020, and produced a thesis titled “High resolution mapping and modeling of the Salamanca magnetic anomaly” (Supervisors: Prof. Puy Ayarza and Prof. J.R. Martínez Catalán; Final score = 9.8/10). In this study, we acquired new high-resolution ground-based magnetic data in order to improve our knowledge of the Salamanca Magnetic Anomaly (SAMA), which was achieved by establishing relationships between magnetic anomalies and lithologies. This led to one co-authored publication by Yenes et al. (2021). Later, I completed a Master’s degree in Reservoir Geology and Geophysics in 2021, and authored a thesis titled “Gravimetric characterization of structural controls on Sn-W ore deposits” (Supervisors: Prof. M. Puy Ayarza Arribas, Prof. J. Alcalde and Prof. M. Linares, Final score = 10/10). In the framework of the iTARG3T project (Galicia, Spain), we applied various geophysical techniques to detect and track the structures that control the ore deposit (Sn-W) and the zones of hydrothermal alteration that can host disseminated mineralization. In particular through a combination of the gravimetric data that I processed and interpreted with magnetic and aeromagnetic anomaly mapping, we were able present an interpretation of the target structures. This work led to one first-authored publication.
In the past years, I have acquired a broad and diverse professional experience from my participation to various research projects in Zaragoza, Salamanca and Burgos. For example, I had the unique opportunity to participate to the 2021-2022 Spanish Antarctic campaign, which eventually led to two (including one first-authored) publications, and obtained funding (AlvarGonzalez Scholarship) to carry out the research study “Magnetic structure of an Antarctic submarine volcano and its relationship with the indications of the ocean floor” at the Royal Observatory of the Navy (ROA). Throughout my scientific career, I have been trained to a wide range of techniques used to solve tectonic problems and to understand the geometry and kinematics of geological structures (e.g., cartography and geological sections, 2D gravimetric and magnetic modeling, fracture analysis and interpretation of seismic profiles), while in the last two years at CENIEH I have been specifically focusing on Quaternary Sciences, and received extensive training in a series of analytical techniques related to Geochronology and Geosciences such as: (i) paleomagnetism and rock magnetism, including data acquisition, and reduction and interpretation, with subsequent first-authored conference presentations; (ii) non-invasive high-resolution analysis of sediment cores using a Multi-Sensor Core Logger maintenance (including magnetic susceptibility and natural gamma-rays), including the maintenance, calibration of the instrument as well as the analysis of 90 m-long cores form the Barranco Leon sequence, which led to a first-authored publication; (iii) stratigraphic and sedimentological interpretation of archaeological and geological sequences (Baza Basin and Atapuerca).
In summary, I have not only acquired a wide range of technical skills, but have also developed a unique multi-faceted expertise in marine and terrestrial geophysical activities, as well as in structural, sedimentological and geotechnical studies. I have been involved in several research grants, (i) working on the characterization of the geometry of the subsoil in orogens and sedimentary basins, and integrating geophysical, petrophysical, and structural data, (ii) studying the tectonic evolution of marine zones through geophysical techniques and the use of structural data to understand the fracturing and hydrogeological mechanisms or (iii) the characterization of sedimentary sequences associated with geological and archaeo-paleontological localities through a wide range of analytical techniques. Through this very diverse work, I also obtained an invaluable training on dissemination activities, and ended up writing and contributing to various manuscripts for publication (including three first-authored papers) and presenting results at Conferences.
Finally, I have been always genuinely interested in the transfer of knowledge activities towards the general public. For example, I worked for a month at the Monsagro Interpretation Center as a guide for tours of the town and museum. I participated in the Geolodía 2022 in Palencia, a popular 1-day event sponsored by the Geological Society of Spain to visit geologically relevant places in the province. At CENIEH I participated as a tour guide in the Researchers’ White Night showing the general public all the geochronology laboratories of the CENIEH. During science week I explained the instruments and tools of the paleomagnetism laboratory while I also participated as a guide to show the analytical facilities available at CENIEH.
