An overview of the last works concerning the Recent environment and bottom sediments in the White Sea is presented. Special attention is devoted to the existing schemes of the modern facies structure. Up-to-date factual material allowed the authors to offer a new version of the facies structure....
High-grade iron ores and bauxites of the Kursk magnetic anomaly (KMA) were formed in weathering crusts on the Early Precambrian ferruginous quartzites and shales, i.e., banded iron formation (BIF). Thus far, weathering crusts on the BIF were considered separately, although they formed...
The rare earth element (REE) composition of host rocks (dolomites, Neoproterozoic Pod’’emsk Formation) and manganese ores (manganese oxides and carbonates of supergene zone) are studied. The Pod’’emsk Formation is subdivided into the lower and upper subformations. The upper Pod”emsk subformation...
The article overviews concepts of the formation of sedimentary sequences of the Belt-Purcell Supergroup, a classical Upper Precambrian section of the Rocky Mountains (North America). Analysis of data on the bulk chemical composition of mudstones of the Belt-Purcell Supergroup (González-Álvarez,...
Drilling recovered the upper part (23 m) of the upland loess–paleosol series (LPS) on the right bank of the Kuma River near the Otkaznoe Settlement. Description of cores and laboratory analyses made it possible to carry out lithostratigraphic subdivision of the loess sequence in the summary...
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...
