Carlos Marín Lechado is a Scientist at the CN Geological and Mining Institute of Spain (IGME, CSIC). Geologist and Technical Mining Engineer completed his doctoral thesis at the University of Granada on the recent tectonic evolution in the south of Almería (South of Spain). He has participated in the GEODE Plan (Continuous Geological Cartography of the Internal Betic Zones) and ALGECO2 Plan (Evaluation of CO2 Geological Storage Areas), among other projects. His main line of research is linked to 3D geological modelling for the characterization of reservoirs (CO2, H2 storage, deep aquifers, etc.). He is especially interested in integrating surface and subsurface information such as geological cartography, geophysical prospecting data, and boreholes.
