Abstract: Samples from drillhole Jamison 1 (held in the NTGS core library in Darwin, Northern Territory) were collected by John Gorter on behalf of ENI and examined by Kathleen Grey as part of a reassessment of the hydrocarbon prospectivity of the Beetaloo Basin. Sixteen palynological samples, four from the Chambers River Formation and twelve from the Kyalla Formation, were prepared using a modified preparation technique. Unfortunately, poor preparation has prevented thorough examination of the some of the samples. Initial examination indicated abundant, diverse, extremely well-preserved palynomorphs from parts of the succession, including many new taxa that could not readily be assigned to existing species or precisely dated. Because of the difficulties presented by these previously undescribed taxa, slides were set aside until time was available for a more detailed examination. Further work has now been carried out, but it still has not been possible to do more than document some of the more common species. A more extensive study is needed to define the taxa present and document their stratigraphic distribution. The general aspect of the assemblage indicates a Mesoproterozoic age. More detailed analyses should provide a biostratigraphic scheme covering much of the Mesoproterozoic Beetaloo Basin succession. Such a scheme would have considerable potential for correlation of hydrocarbon exploration drillholes in the Beetaloo Basin.
