A palynological report on A.O.G. Wentworth No. 1, New South Wales, with observations on the Permian of the Oaklands-Coorabin area of the Murray Basin

Palynological examination of cores and cuttings from the subsidised A.O.G. Wentworth No.1 well, Murray Basin, New South Wales, indicates that the well passed from Tertiary into Lower Cretaceous marine sediments at either 1283-1335 feet or 140-1455 feet and into probable Lower Permian beds at 1615-1645 feet. The well was completed in conglomerates, probably also of Lower Permian age, at a total depth of 2081 feet. Examination of samples from the Oaklands-Coorabin coalfield, to obtain a guide to the age of the pre-Mesozoic section of Wentworth No.1, demonstrated that the coal measures are equivalent in age to the Upper Coal Measures of the Sydney Basin, that they overlie Lower Permian (?)marine beds which, by virtue of their common content of Leiosphaeridae, compare in age with the Wentworth Permian section.
