  • Composition of organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina)

    Nikoleta Aleksić, Aleksandar Kostić, Miloš Radonjić (2021)
    This paper presents the first data on the organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in the East Herzegovina region of the External Dinarides. Representative, organic-rich samples from outcropping sedimentary rocks of different ages in the area (Triassic to Neogene) were selected and analysed. The organic matter was studied by Rock-Eval pyrolysis and under the microscope in reflected non-polarized light and incident blue light. The results obtained show the presence of different types of organic ...

Bitumen and framboidal py- rite were observed in all samples from Triassic to Eocene, but mostly in those from the Jurassic and Cretaceous sedi- mentary rocks.

    ... �e predominant maceral in the Gacko coal sample is atrinite (51%), followed by densinite (39%). Other mac- erals, present in the sample in only small quantities, are corpohuminite (5%) and to a lesser extent textinite, ulmi- nite, fusinite and semifusinite. Correlating maceral composition with ...
