CHARACTERIZATION AND ORIGIN TYPES OF IMMATURE AND LOW-MATURE AMORPHOUS KEROGEN IN TERRESTRIAL SOURCE ROCKS

The microfluorescent technique was applied to investigate the fluoresc ence alteration patterns of amorphous kerogen of the terrestrial sourc e rocks of China. Two fluorescence parameters, I-546(20) and R were su ggested, which can be taken to divide the amorphous kerogen into five types: algae amorphinite, biodegraded amorphinite A, B, C, and humic a morphous. On the basis of this, the Rock-Eval analysis results of sour ce rocks were used to investigate the hydrocarbon generating potential of these amorphinite.
