Figure 16: Proposed radiolarian zones and unitary associations for Bajocian (Middle Jurassic) to Aptian (Early Cretaceous) time interval (after Jud, 1994; O'Dogherty, 1994; Baumgartner et al., 1995; Matsuoka, 1995; Dumitrica et al., 1997; Li et al., 2017; Cui et al., 2021). The shaded area corresponds to the chronostratigraphic position (Hauterivian to early Aptian) of the radiolarian assemblages obtained from the Seyran Formation within the Soğukçam Limestone Group, from the Uyuzhamamı section in the Haymana region.
