Palynological analyses of 31 selected samples taken from uranium exploration rotary drillholes in the eastern Polda Basin indicate three distinct microfloral units - (a) a Late Jurassic assemblage comparable with that from the Polda Formation further west; (b) a Middle Eocene assemblage comparable with that described from the Poelpena Formation in Polda no. 1 well; and (c) a mid-Tertiary assemblage hitherto unrecorded from the basin, which may be correlated with microfloras from the Munno Para Clay of mid-Miocene age. All of the sediments examined were deposited under reducing conditions in a non-marine environment. Whilst difficulties still exist in separating the formations on lithological evidence, the palynological evidence is definitive.
