Chronology of recent sedimentary infill of the Inner Río de la Plata Estuary, Argentina

The Inner Río de la Plata Estuary is a sedimentary depositional system that resulted from fuvial-deltaic activity. Gentle Pliocene-Pleistocene slopes make-up the northern side of the estuary whereas small clifs of the same age constitute the southern side. A long coastal estuarine barrier developed...

description The Inner Río de la Plata Estuary is a sedimentary depositional system that resulted from fuvial-deltaic activity. Gentle Pliocene-Pleistocene slopes make-up the northern side of the estuary whereas small clifs of the same age constitute the southern side. A long coastal estuarine barrier developed at about 6000 years BP when the maximum fooding surface occurred. Attached to this barrier, and at a lower elevation, is a large strandplain (covering an area of about 2400 km2 ) which displays more than 220 beach ridges. In diferent areas, the dating indicates a periodicity of 13.4-13.7 years for the development of each beach ridge.
