This paper addresses the hypotheses of the formation of the brown loams widely spread in the zone with hummocky relief within
the intermontane Razdol’noe-Khanka Depression. These hypotheses were proposed in the 1970s–1980s. The accumulation of information
on the loess formation in southern East Siberia, as well as obtaining new analytical data on the microtextural, mineralogy,
and major and trace-element composition of the brown loams, and the comparative analysis of these deposits provided for the
formulation of a more substantiated view concerning the place of the brown loams in the group of loess-type rocks. 相似文献

In the Ussuri-Khanka depression of Primorye, the Quaternary alluvial-lacustrine and lacustrine sedimentogenesis progressed under conditions of transgressive accumulation in response to the depression tectonic subsidence and recurrent climatic fluctuations. The alluvial dams and irregular accumulation are proved to have been the leading factors of lakes’ formation within the depression. As is shown, fluctuations of the water level in limnic reservoirs depended on the climatic changes. New data considered in this work confirm the lacustrine genesis of a greater part of the Middle Pleistocene-Holocene sedimentary succession in the Khanka depression. Two transgressive phases, when the water level in the lakes rose by 1.5–2.0 m above the present one, are established for the Subboreal. The general conclusion is that the mesorhythmic structure of the sedimentary succession in the Ussuri-Khanka depression reflects the influence of climatic fluctuations in the Late Cenozoic. 相似文献

An analysis is made of the changes in biotic components of landscapes during the Holocene Little Climatic Optimum on the island and mainland shores of the southern Far East which manifested themselves in all landscape zones. Some paleoclimatic parameters and the shift of landscape zones have been assessed. 相似文献

It is shown that the development history of landscapes on Simushir Island includes several stages marked by their reorganizations, which were caused by climate changes and volcanic eruptions. The stratigraphic data derived from sections of the soil-tephra cover in different areas of the island and from the peatland section on the Dushnaya Bay coast served as the basis for the paleogeographic reconstructions. They include data on the palynological spectra of the fossil and recent soils and peatland; the latter also yielded diatom assemblages. The radiocarbon dates and tephrostratigraphic record provided age estimates for the corresponding events. 相似文献

Palynological and geochronological data have been used to ascertain the time history of a unique natural-territorial complex — the relict larch stands that have persisted in the southeastern part of Shikotan Island since the Late Pleistocene. The study revealed the development stages of landscapes. Factors favoring vegetation conservation in the refugium are discussed. 相似文献

Taking into consideration additional data indicating the reorientation of the Razdol’naya River flow in the Pleistocene, a new model of its capture is proposed. The latter is based on the principle of the more aggressive behavior of rivers draining the eastern megaslope of the Sikhote Alin mountainous system, including the river that captured the Razdol’naya River flow. 相似文献

The stratigraphic subdivision of peat in the Gorobets River valley, the largest river on Shikotan Island, is conducted based on the study of palynological and diatom assemblages, tephrostratigraphy, and radiocarbon dating. The study object is one of the oldest peats in the South Kurile region and reflects the development of natural environments beginning from the early Holocene. Nine phases are distinguished in the development of vegetation on Shikotan Island. The changes in vegetable communities were determined by climatic fluctuations during the Holocene. Their ages, the factors responsible for the appearance and extinction of particular coniferous, small-, and broad-leaved taxa, and changes in their landscape-forming role during different periods of the Holocene, as well as specific features in the formation of the present-day vegetation on the Lesser Kurile Ridge representing a separate floral area, are established. In addition to the climatic and sea-level fluctuations, the development of the island landscapes was determined to a significant extent by its topography, size, and isolation. 相似文献
