Holocene evolution of the Mar Chiquita coastal lagoon area (Argentina) indicated by pollen analysis
Palynologycal information was integrated with the aim to study vegetation history and environmental changes in Mar Chiquita coastal lagoon area (in the southeast of Buenos Aires province, Argentina) related to sea-level fluctuations during the Holocene. Prior to 5000 yr BP a mosaic of psammophytic a...
