ESPECIALIZACIÓN Geoquímica, Geoquímica Isotópica, Geocronología. INTERESES Combino herramientas geológicas de campo con geoquímica, petrología y geoquímica isotópica para entender la evolución de los Andes en su etapa más temprana, a lo largo de todo el margen chileno y también en Argentina y el sur de Perú. Utilizo como herramientas la geoquímica elemental e isotópica de roca total y minerales ígneos y metamórficos y el mapeo geológico para determinar las fuentes y mecanismos de emplazamiento de los magmas andinos. Me interesa conocer la evolución de los arcos magmáticos y su relación con la tectónica global durante el mesozoico, y su comparación con los ambientes de margen convergente recientes. También trabajo en la aplicación de métodos geocronológicos en alteración hidrotermal y metamorfismo de muy bajo grado.
