The Mongolian National Permafrost Association is pleased to acknowledge its membership in the International Permafrost Association. Mongolian geocryologists express their appreciation to the IPA Council and its officers.
In 1995, geocryologial field work was carried out on the Khan Khentei protected area, an area of more than 12,000 km² that embraces the Khentei Mountains. As a result of these and previous studies, maps at 1:500,000 of permafrost, seasonal freezing and thawing ground, and the distribution of cryogenic processes and phenomena have been prepared by N. Sharkhuu, D. Tumurbaatar and R. Lomborenchen. According to these maps, large parts of the territory are characterized by continuous permafrost with an average thickness between 50 and 200 m. Average depths of seasonal thaw are 1 to 3 m. There is widespread occurrence of surface icings and stone polygons. Permafrost aggradation associated with climatic change and hydrogeological conditions is observed at several sites.
As a result of geocryological and geothermal research by N. Sharkhuu in the Baganuur mining area in 1976, 1984, 1992-93, and 1995 (prior to and following mining) detailed changes in permafrost conditions have been observed. These results are presented in a chapter (in English) on permafrost and environmental analyses of the Baganuur project. The report includes a permafrost map of the Baganuur d mining area at a scale of 1:25,000, and gives permafrost assessment, prediction and recommendations for monitoring.
