Abstract:
The evolution of the Lanín volcano has been initially proposed from the basis of the study of its western slope. Field description of the deposits hosted in the eastern Argentinian slope has allowed improving the knowledge of this evolution. A reconstruction of the glacial and volcanic history of the area in recent times is carried out in this work which reveals the existence of large avalanches, lahars, lava flows and pyroclastic materials of syn- and post-glacial times. In particular, the interaction between these deposits and those deposited by the ice masses that covered the Lanín volcano allowed identifying two synglacial, one interglacial and two postglacial lava events. The postglacial history of this volcano involves voluminous avalanches related to a partial collapse of the cone summit part, and extensive surge-pyroclastic plains covering the surface of the volcanic edifice. Pyroclastic flows, lahars and pyroclastic monogenetic cones represent the most modern activity registered in the eastern slope of the Lanín volcano. Thus, since the study of the distribution of these sections, a more convulsed recent past than previously thought is revealed.
