Abstract
Sedimentary cores from Mascardi Lake, as well as outcrops, have been studied to reconstruct late Pleistocene and Holocene environmental conditions in northern Patagonia, Argentina. The Mascardi Lake sequence is a key-site for understanding such conditions, providing evidences of ice retreat, volcanic activity and important sedimentation changes. A significant environmental change occurred around 13 ky BP when the great lake named Elpalafquen became several small basins and some of the present lakes from northern Patagonia started to get their current features. The Mascardi Lake occupied a marginal position, close to the ice front at the western side of the paleolake.
