Resumen:
Two phosphogenic events of potential economic importance (preserving P2O5 abundances up to 25 and 35%, respectively) are recognized in the Neoproterozoic Tandilia System. The older of the two lies atop a quartz-arkosic facies association of the Villa Mónica Formation. The age of this unit remains controversial, but has previously been considered as Tonian to Cryogenian based on stromatolite assemblages and carbon isotope trends; strontium isotope abundances of
