Abstract

A study was carried out on the sedimentary stratigraphic units in the Balandra coastal lagoon floor and in the outcrops of its surroundings, which possess the widest registered record known for the late Quaternary of the La Paz bay, including the late Pleistocene.

The oldest Pleistocene unit is represented by a marine terrace located three or four meters above mean sea level, from which a sample of coral was dated using the uranium-series method at 288,000 ± 50,000 years B. P. The age of this unit is considered to be incorrect because the elevation of its top is lesser than other terraces of the region of similar age... In order to continue, download the full article in PDF
