For the first time considered are main features of geochemistry for some individual aromatic and sulfur-organic compound in Kuonamka sediment rocks. It is shown that compositions of aromatic biomarker hydrocarbons and dibenzothiophenes in bitumen of the Cambrian Kuonamka suite depend on the nature of original living substance and its lipid biochemistry as well as on the character of bacterial processes of organic substance transformation at marine sediment diagenesis and in catagenesis. The key factor in diagenesis is the organic substance concentration n sediments and sulfate-ion concentration in supra-bottom water.
