We reconstruct the palaeogeographical evolution of continental shelf in Patagonia for period spanning Last Glacial Maximum (approximately 24 000 calibrated years BP) to Middle Holocene using a global sea level rise curve this and GLOBAL MAPPER 10 software (http://www.globalmapper.com). Our model provides new information future palaeoenvironmental palaeoclimatic reconstructions. expect will be assistance studies designed examine patterns faunal plant population expansion, dispersal, migration...

The climate in southern Patagonia is heavily influenced by the Southern Westerly Winds (SWW). Therefore, reconstructions from this region are valuable for our understanding of temporal dynamics atmospheric circulation Hemisphere. In study a sedimentary record shallow lake Laguna Amalia – located semiarid Fuegian steppe Tierra del Fuego (53°S) was used to how hydroclimate has changed over last ~7100 years. Our interpretations rely on combination pollen, diatoms, total organic carbon,...

Fishing intensification is evidenced in the archaeological record of Beagle Channel region (Tierra del Fuego, Argentina) during late Holocene by significant diachronic increases both representation coastal taxa and diversity pelagic fish species taken. Faunal evidence from Imiwaia I site, however, shows a different pattern temporal variation exploitation contrast to that regional trend. By comparing data palaeogeography archaeoichthyology, we have been able evaluate how changes geomorphology...

Isla de los Estados is a mountainous island southeast of Tierra del Fuego, in southernmost South America. Its central and eastern parts have an alpine topography, transected by U-shaped valleys, small, partly over-deepened fjords, multitude abandoned cirques, all associated with extensive former local glaciations. Traces glacial erosion generally reach 400–450 m a.s.l., above that trimline distinct sharp-edged nunatak derived landscape present. The westernmost part the has lower, more...

The Quaternary infilling of a circular structure located in Bajada del Diablo, Chubut Province, Argentina has been proposed as crater strewn field previous studies. Here we report the finding about 65 microspherules collected trench excavated center structure. majority hand-picked specimens are single, but some them exhibit compound forms. single spherical with mean size 137 μm, whereas more complex samples show peduncles and drop shapes. Dendritic crystal growth is recognized internal...
