Abstract. PALYNOLOGY AND PALYNOFACIES OF A MIDDLE-LATE HOLOCENE MARINEPALYNOLOGY AND PALYNOFACIES OF A MIDDLE-LATE HOLOCENE MARINE
SEQUENCE: ALBUFERA LANUSHUAIA, BEAGLE CHANNEL, TIERRA DEL FUEGO,
ARGENTINA. Palynological analysis, with emphasis on palynofacial analysis was carried
out on Holocene marine deposit located on the northern coast of the Beagle Channel,
Argentina. This analysis allowed paleoenvironmental assessments and paleoclimatic
inferences. A fossil section from Albufera Lanushuaia (54° 52 04.4 S - 67° 60 44.9 O),
located on the northern coast of the Beagle Channel was analyzed. The set of organic
constituents indicate the proximity of the area of continental input to the marine
environments, with distances and/or times of transport relatively short. The presence of
pyrite suggests reducing conditions, probably associated with marginal-marine
environments. At the Albufera Lanushuaia, from the ca 5,800 years cal B.P., palynological
associations reveal the same pattern of regional vegetation with a closed forest of

out on Holocene marine deposit located on the northern coast of the Beagle Channel,
Argentina. This analysis allowed paleoenvironmental assessments and paleoclimatic
inferences. A fossil section from Albufera Lanushuaia (54° 52 04.4 S - 67° 60 44.9 O),
located on the northern coast of the Beagle Channel was analyzed. The set of organic
constituents indicate the proximity of the area of continental input to the marine
environments, with distances and/or times of transport relatively short. The presence of
pyrite suggests reducing conditions, probably associated with marginal-marine
environments. At the Albufera Lanushuaia, from the ca 5,800 years cal B.P., palynological
associations reveal the same pattern of regional vegetation with a closed forest of
Nothofagus and an assemblage of Peridiniales dinocysts dominated by taxa that suggest
marginal-marine environments, with low to moderate salinity and high nutrient
concentrations in shallow marine waters, probably due to the contribution of freshwater
due to surface runoff. For the past 2,000 years, a decrease in pollen records of Nothofagus
marginal-marine environments, with low to moderate salinity and high nutrient
concentrations in shallow marine waters, probably due to the contribution of freshwater
due to surface runoff. For the past 2,000 years, a decrease in pollen records of Nothofagus

and an increase shrub and herb pollen with a limited occurrence of aquatic palynomorphs
were observed. These reflects the development of a more open forest and adjacent areas of
herbaceous and shrub with marginal-marine influence, associated to a regressive event.
