Abstract
Palynological analyses have been undertaken on four fully cored boreholes in the central west Murray Basin (Woodlands-1, Manilla-1, Piangil West-2 and Hatfield-1 holes) to provide a biostratigraphic framework for geological factors related to groundwater. Three of these boreholes penetrated the marine sequence of the Geera Clay and its associated facies, which acts as an aquitard confining groundwater flow within the aquifers of the Renmark Group. This study has been augmented by analysis of cores and cuttings from boreholes in the areas east of the main marine influence, and by reference to previously studied sequences at Oakvale-1, on the western margin of the basin. Early Cretaceous sediments of non-marine character are present at Manilla-1 and at Mitfords Corner in the Wentworth Trough. -from Authors
