Fig. 6 Palynofacies composition, palaeoenvironment and thermal maturity interpretations inferred for the studied section. Thermal maturity estimation of organic matter is compiled after several authors (e.g., the spore/pollen color changes correlated with TAI values are adapted from Pearson, 1984; the correlation of TAI and SCI values with hydrocarbon stages —immature up to overmature— are adapted from Hartkopf-Fröder et al., 2015). The palaeoenvironment interpretation (proximal–distal palynofacies), according to Jurkowska & Barski (2017). AOM: amorphous organic matter; Op-Eq: equidimensional opaque phytoclast; Op-la: lath-shaped opaque phytoclasts; TP: translucent phytoclast; MDOP: mean diameter of opaque phytoclasts. The mean diameters of the phytoclasts (in µm) were obtained by counting at least one hundred of phytoclasts from each sample; TAI: Thermal Alteration Index; SCI: Spore Color Index
