Fig. 6 in Integrated palynology and sedimentology of the Mississippian of the Tisdafine Basin (Eastern Anti-Atlas, Morocco)
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

Microfacies 2b (or MF2b) consists of a fine−grained bioclastic and peloidal packstone. Abundant dasycladaceans algae (center of the picture), ostracods and foraminifers. Thin section PG7. B–D. Microfacies 4c (or MF4c) corresponds to a medium− to coarse grained crinoidal grainstone rich in subrounded microbreccias. The microbreccias are composed of algal mats with irregular thin fenestrae and a few peloids (center of D).

Microfacies 4b (or MF4b) is a coarse grainstone−rudstone with rare micritic oolites. The bioclasts are dominated by crinoids and brachiopods, rare dasycladaceans algae, ostracods and foraminifers. Intraclasts are present, and a few are encrusted by small tubular algae (Girvanella?). A small synsedimentary inverse fault is observed in the center of the picture. Graded bedding is present. The grainstone texture is episodically interrupted by thin stromatolitic mudstone laminae (white arrows). Thin section PG27. G, H.
