“…Typical pollen grains of Eucommiidites are first recorded in the fossil record during the Triassic, and their stratigraphic range extends through the Mesozoic into the Late Cretaceous (Pedersen et al, 1989). Somewhat similar grains, Pretricolpipollenites bharadwajii Balme, are also known from the late Permian (Tekleva et al, 2019).…”

“…In the absence of independent paleontological evidence, it is difficult to accurately date the Umm Irna Formation, however its overall palynological character suggests an age range within the Guadalupian (mid Permian) to Lopingian (late Permian), and the presence of the pollen Pretricolpipollenites bharadwajii mainly recorded from the very latest Permian of the Salt Range of Pakistan and the Triassic in the Middle East and North Africa suggests an age within the later part of that range (Stephenson and Powell, 2014;Tekleva et al 2019).…”

Palynological study of the Arqov and Saad formations of the Negev, Israel, in Avdat-1 borehole has allowed comparison with the assemblages of the Umm Irna Formation of the Dead Sea, Jordan. Core 7 of Avdat-1 (Saad Formation) contains common Hamiapollenites dettmannae and Distriatites insolitus indicating that it correlates with the Arabian Peninsula OSPZ5 Biozone and therefore has a likely Roadian-Wordian age, rather than a Westphalian age as previously suggested. Core 6 contains Indotriradites mundus, whose first appearance indicates the base of OSPZ6 (Wordian, extending into the Capitanian), but also contains common Protohaploxypinus uttingii, Pretricolpipollenites bharadwajii and Thymospora spp. As such, the assemblages of Core 6 are most similar to those of the Umm Irna Formation, while those of Core 7 are older, as implied by the correlation of Core 7 with OSPZ5. An interesting difference between typical OSPZ6 assemblages and those of Avdat-1 Core 6 is the common presence of Falcisporites stabilis in the latter. This pollen was produced by the corystosperm plant Dicroidium and its presence in Core 6 further indirectly confirms previous suggestions that Dicroidium (once considered confined to the Triassic) existed in the pre-Triassic in the Middle East. The difference in thickness in Permian sediments between Avdat-1, eastern Negev boreholes, and the Umm Irna Formation may be due to greater accommodation space provided by a southwestward extension of the Palmyrid depocenter, or perhaps subsidence related to a fault in a similar position to the present Dead Sea Fault, or a fault ancestral to the Dead Sea Fault.

A survey of the palynostratigraphy of the strata above and below the Hercynian Unconformity (HU) indicates that the range of its associated hiatus, due to either non-deposition or erosion (or both), varies considerably across the Arabian Plate depending on the position of the succession in relation to the three main highs or arches, the Levant, Al Batin, and Oman-Hadhramaut arches, and any Hercynian faulting or other uplift in basinal regions, for example in the Ghawar region. As expected, the succession spanning the HU is most complete in basinal areas, for example in the Faydah-Jafurah and Nafud-Ma'aniya basins. The well with the shortest hiatus corresponding approximately to a maximum duration of part of the Serpukhovian and Bashkirian, appears to be KH-5/1, close to the axis of the Nafud-Ma'aniya Basin. Palynological assemblages in rocks above the HU indicate the diachronous onset of the basal Khuff clastics northwest through the Arabian Plate over a period of around 15 my. The oldest strata above the HU across the Arabian Plate also indicate systematic variation, probably due to palaeoclimate, with assemblages of similar age in Iraq and northern Saudi Arabia showing some similarities to those of Oman, but differences probably due to a strong climatic gradient at the time.
