CALCAREOUS DINOFLAGELLATE AND CALPIONELLID DATING The biostratigraphy of the Kimmeridgian and Early Ti- thonian deposits studied is based on the calcareous dinofla- gellate and calpionellid succession (see Jach ef a/., 2012). Cysts of the calcareous dinoflagellates are gencrally ...
... and Ždiarska Vidla sections (Figs 6, 7) is dated precisely by means of calcareous dinoflagellates as belonging to the Mo- luccana Zone of the Late Kimmoeridgian. Post-radiolarite deposits Calcareous dinoflagellates and carbon isotope data (number 8 in Fig. 15) allow estimation of the onset ...

More precise dating refers to the Late Kimmeridgian and Early Tithonian, where calcareous dinoflagellates per- mit the recognition of discrete zones, starting from the Late Kimmeridgian calcareous dinoflagellate Moluccana Zone in the upper part of red radiolarites (Jach ef al., 2012) ...Renata Jach, Nevenka Đerić, Špela Goričan, Daniela Reháková.

A comparative study of the molecular and isotopic composition of biomarkers in immature oil shale (Aleksinac deposit, Serbia) and its liquid pyrolysis products (open and closed systems)
Gordana Gajica, Aleksandra Šajnović, Ksenija Stojanović, Jan Schwarzbauer, Aleksandar Kostić, Branimir Jovančićević (2021)The molecular and isotopic composition of biomarkers in initial bitumen isolated from immature (0.41% Rr) oil shale samples (Aleksinac deposit) and liquid products obtained by pyrolysis in open (OS) and closed (CS) systems are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in liquid products is determined. The applicability of pyrolysis type, numerous biomarkers and carbon isotopic compositions (δ13C) of n-alkanes in liquid pyrolysates is established. Pyrolysis experiments were ...Uljni šejl, Aleksinac, organska supstanca, otvoreni i zatvoreni sistem pirolize, biomarkeri, izotopski sastav ugljjenikaGordana Gajica, Aleksandra Šajnović, Ksenija Stojanović, Jan Schwarzbauer, Aleksandar Kostić, Branimir Jovančićević.
