- Organic geochemistry of Oxfordian carbon-rich sedimentary rocks of the Russian plate. Bushnev, D.; Shchepetova, E.; Lyyurov, S. // Lithology & Mineral Resources;Sep2006, Vol. 41 Issue 5, p423
The lithology and geochemistry of upper Oxfordian sedimentary rocks enriched in marine organic matter (OM) have been studied. These rocks occur as a persistent unit of Upper Jurassic rocks exposed on the right bank of the Unzha River in the Kostroma district. The OM was investigated in detail in...

- Metasedimentary rocks of the paleoarchean Dniester-Bug Group, Ukrainian Shield: Composition, age, and sources. Lobach-Zhuchenko, S.; Balagansky, V.; Baltybaev, Sh.; Artemenko, G.; Bogomolov, E.; Yurchenko, A.; Stepanyuk, L.; Sukach, V. // Lithology & Mineral Resources;Sep2014, Vol. 49 Issue 5, p381
Paleoarchean granulite-facies metasedimentary rocks (quartzites, garnet quartzites, garnet-pyroxene gneisses, pyroxene-magnetite and magnetite quartzites) attributed to the Dniester-Bug Group of the Ukrainian Shield were studied. On the basis of geochemical data, including REE, the primary...
- Lithogenesis types and their modern interpretations. Kholodov, V. N. // Lithology & Mineral Resources;Nov2010, Vol. 45 Issue 6, p519
Based on the comparison of early and late works by academician N.M. Strakhov, typification of lithogenesis, which covers the entire recent sedimentation on continents and in the oceanic segment of the Earth, is proposed. It is shown that early stages of sedimentogenesis play a decisive role in...
- Problems of the Stadial Analysis and Development of Lithology. Kholodov, V.N. // Lithology & Mineral Resources;Mar/Apr2004, Vol. 39 Issue 2, p95
History of the evolution of concepts concerning stages of sedimentary rock formation is reviewed to show the conditional character of stadial boundaries and unreasonableness of their detailed subdivision. An insufficient knowledge of continental diagenesis is stressed and some problems of...
