RT Journal Article T1 Sr and Nd isotope data from the fluorspar district of Asturias,northern Spain A1 Sánchez Pérez-Cejuela, Virginia A1 Corbella, Mercè A1 Fuenlabrada Pérez, José Manuel A1 Vindel Catena, Elena A1 Martín Crespo, Tomás AB The origin and age of the hydrothermal fluids related to the precipitation of fluorite, barite and calcite in the Villabona, LaCollada and Berbes localities (Asturias fluorspar district, N Spain) have been evaluated from Sr and Nd radiogenic isotopes. Srisotope data (87Sr / 86Sr=0.7081 to 0.7096) are compatible with mixing between seawater and a more evolved groundwater thatinteracted with the basement. From Nd isotopes in fluorite, an isochron age of 185±29 Ma (Lower Jurassic) was obtained,consistent with other hydrothermal events in the Iberian Peninsula and Europe. These constraints are essential to proceed with aquantitative model for the genesis of the mineralization that includes fluid and heat flow together with reactive transport of solutes.
