The assessment of the groundwater resource sustainability in the European part of Russia

Abstract

This article presents a method to assess the resistance of groundwater resources to anthropogenic impact and the fresh groundwater withdrawal as well as the results of such assessment for different territories of the country ranging from a federal district or a region to an artesian basin. The assessment was carried out with the help of the system of indicators and indexes of groundwater resource sustainability under the influence of groundwater withdrawal developed by the author.

CHPP related anthropogenic impact zones

Abstract

This article offers a concept of an integral CHPP related anthropogenic impact zone (AIZ), representing a complex of industrial units, organizations and communications, which support the life cycle of a CHPP. The author conducted an analysis of the basic features of an integral CHPP AIZ and its elements. This concept may have a certain theoretical significance in solving optimizing environmental problems at the level of individual territories and the country in whole.

A study of the statistic properties of the distribution of thermokarst lakes in the West Siberian cryolithic zone on the basis of satellite images

Abstract

The location of thermokarst lakes on the research territory in the permafrost zone of Western Siberia is identified with the use of satellite images. The statistical data analysis shows that the empirical laws of spatial distribution of the lake centers on the plane correspond to the uniform distribution law.

The geochronology of the Holocene vegetation deve¬lopment in the South-east Baltic region (based on the results of a paleogeographic study)

Abstract

This article presents the results a of complex palaeogeographical study of Velikoye peat bog (the Šešupė River basin, the Kaliningrad region). The pollen analysis accompanied by radiocarbon dating, makes it possible to reconstruct the vegetation development, on the basis of which the climate changes in the South-east Baltic region over the Atlantic-Subatlantic periods of the Holocene can be tracked.

The identification of the predominant age of the crystalline basement of continental and ocean platforms

Abstract

This article presents the evidence of the ancient origin of crystalline basement of the platform areas of the Earth developed as a result of global volcanism in the Hadean (more than 4 Ga). In the late Mesozoic-early Cenozoic, another outbreak of volcanism and dehydration of subsoils led to a significant subsidence (8—10 km) of continental masses and the formation of the World Ocean.
