Research highlights
  • Summarizing the research results of the mineral composition features of marine and ocean sediments
  • Establishing statistically stable parageneses of heavy minerals that are regularly repeated in sedimentation basins that are similar in structural-tectonic (geodynamic) and landscape-dynamic (lithodynamic) sedimentation conditions. Developing indicative lithogeodynamic diagrams tallowing to classify the deposits depending on structural-tectonic (geodynamic) conditions of their formation based on associations of heavy minerals.
  • Discovering a large ore occurrence of barite mineralization associated with the activity of cold gas-fluid emanations (cold seeps) in the Eastern part of the Deryugin basin (Sea of Okhotsk)
  • Discovering a new manifestation of carbonate-barite mineralization on the Western slope of the Kuril basin, which was associated with the migration of hydrocarbon (mainly methane) and barium-containing cold gas-fluid flows coming not only from surface reservoirs, but also from deeper sources, associated with mud volcanism
  • Systematizing lithological evidences of gas-fluid emanations and accompanying gas-hydrates on the North- Eastern slope of Sakhalin island
  • Proposing a tephrostratigraphic correlation of Quaternary deposits of the marginal seas of the Far East based on a comprehensive study of the material composition of tephra layers. Estimating the possibility of using distal tephra mineral composition for the purposes of correlation and identification with large explosive volcanic eruptions.
