Datación de eventos tectónicos mediante integración de geocronología K-Ar y análisis de paleoesfuerzos en el Domo del Tormes Antón López, Loreto Muñoz Martín, Alfonso Vicente Muñoz, Gerardo De Galindo Francisco, María Del Carmen 550.93 K-Ar dating Palaeostress Tectonic events Domo del Tormes Geología estratigráfica 2506.19 Estratigrafía The present paper deals with K-Ar absolute dating performed on three fault gouges structures selected across the geological structure known as the Domo del Tormes (Zamora-Salamanca, Spain). The dating performed on five clay samples, with grain size of 0,2-0,4mm and <0,2mm, provides ages from 210 ± 11 to 86,9 ± 4,3 Ma. The interpretation of the results obtained by both geocronological and fault population analysis methods contributed relevant data to ascertain the age of the various palaeostress fields defined in the study area, with maximum horizontal compression oriented E-W and NE-SW.
