AbstractGeomorphological mapping revealed five terminal moraines in the central Verkhoyansk Mountains. The youngest terminal moraine (I) was formed at least 50 ka ago according to new IRSL (infrared optically stimulated luminescence) dates. Older terminal moraines in the western foreland of the mountains are much more extensive in size. Although the smallest of these older moraines, moraine II, has not been dated, moraine III is 80 to 90 ka, moraine IV is 100 to 120 ka, and the outermost moraine V was deposited around 135 ka. This glaciation history is comparable to that of the Barents and Kara ice sheet and partly to that of the Polar Ural Mountains regarding the timing of the glaciations. However, no glaciation occurred during the global last glacial maximum (MIS 2). Based on cirque orientation and different glacier extent on the eastern and western flanks of the Verkhoyansk Mountains, local glaciations are mainly controlled by moisture transport from the west across the Eurasian continent. Thus glaciations in the Verkhoyansk Mountains not only express local climate changes but also are strongly influenced by the extent of the Eurasian ice sheets.

Abstract The article addresses a conflicting encounter of two ideologies of kinship, ‘natural’ and ‘religious’, among the newly established Evangelical communities of Nenets in the Polar Ural and Yamal tundra. An ideology of Christian kinship, as an outcome of ‘spiritual re-birth’, was introduced through Nenets religious conversion. The article argues that although the born-again experience often turned against ancestral traditions and Nenets traditional kinship ties, the Nenets kinship system became a platform upon which the conversion mechanism was furthered and determined in the Nenets tundra. The article examines missionary initiatives and Nenets religiosity as kin-based activities, the outcome of which was twofold. On one side, it was the realignment of Nenets traditional kinship networks. On other side, it was the indigenisation of the Christian concept of kinship according to native internal cultural logic. Evangelical communities in the tundra were plunged into the traditional practices of Nenets kinship networks, economic exchanges, and marriage alliances. Through negotiation of traditional Nenets kinship and Christian kinship, converted Nenets developed new imaginaries, new forms of exchanges, and even new forms of mobility.

The first results of U-Pb LA-SF-ICP-MS-dating of detrital zircons from terrigenous deposits of the Miniseishor suite of the Nyarovei series of the Harbei anticlinorium of the Polar Urals are presented. The series has a presumably Middle Riphean age and lies at the base of the section of the Polar Ural Upper Precambrian. The data obtained give grounds to limit the lower age interval for the formation of sediments of the Minisejshor suite abroad 660 million years ago. Allotment the Nyarovei series as a Middle Riphean straton is erroneous. Formation of the whole cut the Nyarovei series occurred in a relatively narrow age range at the end of the late Riphean. The dominant role in the formation of deposits of the entire series belonged to the products of erosion close arrays of deeply metamorphosed rocks.

The subject of this article is the pollen spectra of the samples from the surface of Romantic's Glacier, located in the Polar Urals in the Rai-Iz mountain range, as well as generalization of the results of published studies dedicated to glaciers of the Urals. The author also examines the pollen spectra of massive ice, which can be attributed to ice of atmospheric origin on the basis of similarity with the pollen spectra obtained from the surface of the glacier. The article reviews climatic peculiarities of the Polar Urals due to the existence of glaciers below the snow line, namely the landscapes of the Polar Urals, including vegetation as a source of pollen and spores falling onto the surface of glaciers of the Polar Urals, as well as possibility of distant pollen drift to the surface of Romantic’s Glacier. The main result consists in the conclusion that the composition pollen spectra of the Romantic’s Glacier in the Rai-Iz mountainous area is mainly determined by the long-range transport of pollen and spores from the western and south-western regions in a latitude direction. The pollen spectra obtained from the surface of the Romantic’s Glacier are characterized by significant presence of various pollen from broad-leaved rocks of lip, maple, oak, and hazel. Pine pollen and high forest birch are prevalent. Local vegetation is very poor. However, the pollen spectra indicates pollen of heath and crowfoot family, and grasses.
