【 摘 要 】

The specific sediment features in Georgiev (J3kmgr), Bazhenov (J3vbg) and Kulomzin (K1bkl) suites, exposed by drilling in the S-E Nurolsk depression (Tomsk Oblast), were defined and described via petrographic, X-ray diffraction and fluorescence-microscopy analysis methods. The classification of agrillites was identified, the structure-texture features, composition, voids and bitumen types and their distribution were determined. It was defined that Bazhenov suite argillites are characteristic of fine-dispersion, high biogenic silica content and scattered organic matter, enriched multi-composite syngenetic bitumen (from light to resin- asphaltine), as well as fractured surface where the migration of light bitumen occurs.
