The presence of permafrost shapes the Andean landscape in a characteristic way through particular landforms and surface features (like rock glaciers, patterned ground, solifluction forms, etc), but also affects the development of the soil. Together with present volcanic processes permafrost has a decisive role for the occurrence of soil and site genesis, special pedological phenomena and the colonization of young, extreme environments. The evolution of life and the habitat conditions are strongly linked with extreme natural conditions which are associated with permafrost and volcanism. The mechanism that triggers pedological activity seems to be connected with temperature changes (freezing and thawing) and special physico-chemical reactions in the volcanic ashes.

There are no references about these topics in Argentina yet and about the area of the active Peteroa volcano (35o 15’ S and 70o 35’ W, 4107 m ASL), in the province Mendoza, there are no geocryological data either. The area combines such extreme conditions. We presented a cooperation project to analyse these phenomena from a geocryological and pedological point of view. The objectives of the studies are the understanding of the main periglacial processes and the main soil formation (protosoils) with focus on the microbiological processes.

It is planned to start in 2006 with the inventory and mapping of cryogenic landforms of the key sites inluding sampling and analyses of selected pedological and stratigraphical profiles, which are affected by cryogenic and volcanic processes. Sediments, soils and plants will be analysed at the Department of Earth Sciences of the University of Hamburg.

The cartography in detail, with the inventory of periglacial landforms and presence of permafrost, will be part of the geocryological South American mapping project. The latter is part of a major project supported by the „Asociación Argentina y Sudamericana del Permafrost“ (AASP), in collaboration with the International Permafrost Association (IPA). The results will be presented at the International Permafrost Conference in Alaska in 2008.
