The Geochronology Facility, within the Research Support Center of Earth Sciences and Archaeometry of the Complutense University of Madrid provides precise isotopic compositions in radiogenic systems.

The laboratory is dedicated to the analysis of isotope ratios in various radiogenic systematics (Rb-Sr, Sm-Nd and common Pb) by using themal ionization mass spectrometry (TIMS). These analyses are carried out in diverse geological materials (water, soil, fossil, mineral and whole-rock samples) and the results can be applied both to obtain absolute ages (Geochronology) and to study geological processes (Isotopic Geochemistry). The absolute ages of rocks and minerals provide the age of the geological processes taking place in the Earth's lithosphere, while isotopic composition is also a tracer of the origin of magmas, as well as of the fluids involved in crustal processes (e.g. formation of mineral deposits, sedimentary processes, geochemistry of surface waters).

The Geochronology Facility supports pure and applied research programs in the Complutense University of Madrid, as well as from national and international universities and scientific institutions.
