We used Rock Eval pyrolysis to examine a peat collection in the Gursky field (located in the Lower Priamurye) during the early stages of diagenesis. This study focused on the top 350 cm of peat, and it also studied the producers of the organic matter. A pyrogram of peat consists of the superposition of three peaks that represent hydrocarbons that desorb at low temperatures (400°C). These peaks represent the lipid, labile, and kerogen components, respectively. We found that diagenetic transformation of organic material was followed by a gradual reduction in lipid and labile components and a simultaneous increase in the kerogen component. This effect is most intense in the top portion of the studied section |
