Description :
Here, the feasability of establishing a tephrochronological framework for central Argentina is examined within the context of a pilot study sited in the area of Andean Piedmont west of Mendoza. The intersite discrimination and correlation of tephra layers on a geochemical basis is examined, with indirect chronological control for the eruption of each generated by optical dating.
