Aromatic compounds in bitumoids of the Bazhenov Formation in the North of the Khantey hemiantheclise
The main features of the geochemistry of individual aromatic compounds (phenanthrenes, dibenzothiophenes, mono- and triaromatic steroids) in chloroform extracts (bitumoids) from the open (regular form and coarse-crushed (≥0.5 cm) samples) and closed (fine-crushed (0.25 mm) samples) pore space of the...
