Abstract: Palynological analyses were carried out on thirty-six samples from boreholes A13, E15 and L7 in the lowland Seberang Prai and Kuala Kurau areas of North-West Peninsular Malaysia. More than seventy pollen types and a total of thirty-one fern spores were identified and differentiated. Pollen diagrams were constructed from selected taxa which are ecologically significant or when the occurrence is representative in the profiles.
The depositional sedimentary environments recognised from the ecological assemblages in the pollen and spores include mangrove, back mangrove and open swamp conditions. The mottled clay layers representing the pollen zones 0 and VII were interpreted to be deposited in a period of low sea level before the last transgression.
The significance of palynology in the Quaternary stratigraphy of the area is well demonstrated. The Gula and probable Simpang Formations are delineated in all the boreholes. The Beruas Formation constituted the uppermost layer in core A13 while the basal horizon in L7 is inferred as the Kempadang Formation.
