The new "Grupo Argentino de Geomorfologos" (GAG) was founded in 1994 and has now affiliated with the International Association of Geomorphologists. The GAG has 13 different research fields, among them Periglacial Geomorphology. The
GAG will organize the First Argentine Meeting of Geomorphology in 1996 in the city of Salta (NOA, Argentine Northwest).
The host will be the National University of Salta (F. Rivelli). The GAG meeting, which coincides with the 6th meeting of the Argentine Association for Permafrost (AAP), will discuss different topics, advance geocryology in Argentina, and address financial problems for research projects, because of the continuing economic difficulties.
D. Trombotto moved from Patagonia to IANIGLA, where he will be in charge of its Geocryology Group and represent the AAP in the IPA. The Mendoza-based group is working on the following topics:
- Fossil cryogenic studies in the Precordillera of Mendoza (A. Corte and E. Buk)
- Fossil permafrost in Patagonia (D. Trombotto)
- Periglacial hydrology (E. Buk)
- Soil studies with seasonal freezing (C. Regairaz)
- Maps of freezing index and frequency
Arturo Corte continues his studies in relation to the deposition of carbonates in cold environments connected with the Lanzhou Institute of China (Chen Xiaobai) and with Strasbourg University, France (Thea Vogt).
Dario Trombotto finished the first short inventory of cryogenic forms and structures in southern South America (in print in Heidelberger Geographische Arbeiten). It includes a chronology of cryogenic events and identifies two important events in southern Argentina (Patagonia). He resumed studies on the behavior of snow patches, which are decreasing at 4300 m a.s.l. in the Cordón del Plata (33°S), Mendoza. He also began new cryogenic studies and inventories in the protected Provincial Natural Area of Laguna del Diamante (34°S).
Enrique Buk marked the new limits of the 0° isotherm at 32°54's at 3860 m a.s.l. in the Central Andes, Cordón del Plata, the rock glaciers in the Morenas Coloradas, in areas with active rock glaciers at 3600 m a.s.l. He associated the variation with recent climatic changes.
Cecilia Regairaz is working on dating of till deposits up to 2400 m a.s.l. in the Cordillera Frontal, based on soil profile weathering. The Mendoza Group hosted Prof. Kazuo Shimokawa of Sapporo University for a year in Argentina and received a German student, Martin Raithelhuber of Heidelberg University, for three months. Future topics for the Mendoza Group are:
- Remeasuring creep in rock glaciers and solifluction lobes (D. Trombotto and E. Buk)
- New cryogenic studies in the region of the Laguna del Diamante (D. Trombotto)
Among other AAP members, A.-L. Ahumada (National University ofTucuman, NOA) continued her minero-cryogenic research on heavy minerals from the Central Andes and the Antarctic.
A. Igarzabal (Salta University) presented work on cryoplanation surfaces in Puerta de Tastil (Salta). H. Schobinger (Mendoza) finished editing a book with contributions from many authors about the mummy of Aconcagua that was preserved in a cryogenic environment. S. Grosso (La Pampa) is working with fossil features in northern Patagonia. G. Martinez and others of the Centro de Geologia de Costas y del Cuaternario (Mar del Plata) worked on fossil debris slopes of the Sierra de 10s Padres, Tandil and Olavarria (Province of Buenos Aires). The Mendoza group has contributed to IPA working groups on Terminology (A. Corte, D. Trombotto and E. Buk) and Mountain Permafrost (D. Trombotto).
