- •
A well-preserved palynomorph assemblage was recovered from the Ratawi and Zubair formations except for the Yamama Formation.
- •
A monospecific assemblage of Subtilisphaera, constitutes the first record of the Subtilisphaera ecozone in Iraq.
- •
Integrated results of palynofacies and Rock-Eval pyrolysis reveal the following:
- •
Samples with high TOC and HI values contain abundant AOM, as is the case of the Yamama Formation.
- •
Samples with lower TOC and HI values contain terrestrial and inertinite fragments and a dearth of fluorescing AOM.
