Для него характерен полигональный микрорельеф и пятнистость, внешне напоминающая медальоны тундры. Объект является уникальным и практически не изученным ландшафтным комплексом. Проведенные исследования выявили комплекс реликтовых криогенных признаков: полигональный рельеф со стороной полигона в среднем 5 м; грунтовые клинья, приуроченные к ложбинообразным понижениям между полигонами; криотурбированность почвенного профиля, и палеокриотекстуры. Полученные данные позволили впервые обосновать палеомерзлотный генезис полигонов. Установлено, что меловые полигоны являются разновидностью реликтового криогенного микрорельефа, сформировавшегося в валдайский криохрон в условиях криоаридного климата, многолетней мерзлоты, морозобойного растрескивания грунтов и роста полигонально-жильных льдов.</p></abstract><trans-abstract xml:lang="en"><p>Specific landscapes defined as chalky polygons can be found formed on chalky rocks under a continental climate across the south-east of the East European Plain. Theses landscapes are characterized by polygonal microrelief and spotting, outwardly resembling tundra medallions. Such landscape complexes are unique and practically not investigated. Our investigation showed a number of relict cryogenic features: polygonal relief with the polygon side averaging 5 m; ground wedges associated with hollow-like depressions between polygons; cryoturbation of soil profiles, and paleocryotextures. The results suggested the paleofrost genesis of chalky polygons. Chalky polygons were found to be a kind of relict cryogenic relief formed in the Valdai Cryochron in conditions of cryoarid climate, permafrost, frost cracking of soils and the growth of polygonalvein ice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неоплейстоцен</kwd><kwd>реликтовая криогенная морфоскульптура</kwd><kwd>псевдоморфозы</kwd><kwd>криотурбации</kwd><kwd>морозное пучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Neopleistocene</kwd><kwd>relict cryogenic morphosculpture</kwd><kwd>pseudomorphs</kwd><kwd>cryoturbations</kwd><kwd>frost heaving</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Institute for Steppe Research Theme No. АААА-А21-121011190016-1, RFBR grant 20-05-00556, Development program of the Interdisciplinary Scientific and Educational School of Lomonosov Moscow State University titled “Future Planet and Global Environmental Change” No. 121051100164</funding-statement><funding-statement xml:lang="en">Institute for Steppe Research Theme No. АААА-А21-121011190016-1, RFBR grant 20-05-00556, Development program of the Interdisciplinary Scientific and Educational School of Lomonosov Moscow State University titled “Future Planet and Global Environmental Change” No. 121051100164</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Butakov G.P.
