Quaternary glaciolacustrine deposits around a Triple Junction site: Paleolakes at the foot of the Northern Patagonian Ice field (Argentina and Chile)

Abstract: The area involved by the triple junction between the South American, Nazca and Antarctic plates activity was affected by Quaternary glaciations. Before 12,800 yrs BP an extended ice field occupied the top of the Patagonian Andes, irradiating glaciers towards the east and the west dominantly. Towards the east, the ice melted in piedmont lakes; towards the west, fjords melted into the Pacific Ocean. The Upper-Pleistocene climate amelioration caused the recession of those glaciers. Some piedmont lakes reversed th… Show more

“…Different authors describe the formation of this large lake connecting the GCBAL and Cochrane-Pueyrredón Lakes, whose level stabilizes around 350 m a.s.l. before the opening of the Baker River Valley (Turner et al, 2005;Bell, 2008;Glasser et al, 2016;Hein et al, 2010;Martinod et al, 2016;Thorndycraft et al, 2019;Isla and Espinosa, 2021). Certainly, an age of deglaciation before 13.4-14.2 ka is not in agreement with a glacial advance through the BRV that would have reached the Bayo Pass at 10 ka, as proposed by Glasser et al (2012).…”
