Abstract
The results of long-term studies of the heavy mineral composition in Neopleistocene basal moraines, carried out according to a unified technique in numerous outcrops in the European Russian Subarctic, are summarized. The heavy fraction of moraines was formed due to the transport of material from three different glacial feeding provinces: distal, transit, and proximal. With the activation of glacier dynamics and increase in the exaration activity of the mainland ice, local features of the underlying rocks had a decisive influence on the moraine composition. Taking into account other lithological data, the established age and spatial tendencies of regular variability in the mineral composition of different-age moraine horizons made it possible to identify reliably their stratigraphic position.
期刊介绍：
Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
