| dcterms.abstract | In the Depressed Pampa of Buenos Aires Province, two regions can be differentiated: the continental and the coastal marine plain environments. Geomorphological characteristics and sedimentary sequences of both sectors preserve evidences of the climatic conditions under which they were generated. In morphogenesis periods -in the foodplain of the Salado river- lithostratigraphic units were deposited in the form of fluvio-lacustrine sediments with radiocarbon ages between 14 ka and 0,5 ka in the Late Pleistocene and Holocene. In the coastal marine plain there are deposits of the MIS 1 marine ingression of circa 6 ka, with a later and gradual retreat of the sea. In periods of environmental stability soils were formed. Among them the geosoils Puesto Callejón Viejo and Puesto Berrondo have been individualized and dated on their type sites with radiocarbon ages corresponding to the Late Holocene. The 14C ages in years BP were determined using bones of extinct megamammals, shells of marine and fresh water invertebrates and organic matter from the lithostratigraphic and pedostratigraphic units. The climate during the Late Pleistocene was arid-semiarid. In the Holocene there were alternations to warm-humid. This study provides information on the feasibility of areas for human settlements and for studies requiring contributions of a chrono/lithoestratigraphic nature. | en |
