Palynological Report For Wentworth Well And Oaklands-Coorabin Coalfield

A palynological report by the Australian Ocean Data Network details fossil analysis from the A.O.G. Wentworth No.1 well and the Oaklands-Coorabin coalfield in New South Wales. The report interprets stratigraphic transitions, identifying Tertiary to Lower Cretaceous and Lower Permian sediment layers based on microfossil content. It was last updated in April 2026.

Use Cases

• Correlating sediment age between the Wentworth well and the Oaklands-Coorabin coalfield using reported fossil assemblages like Leiosphaeridae.
• Identifying stratigraphic boundaries, such as the transition from Tertiary to Lower Cretaceous marine sediments reported at depths of 1283-1335 feet or 140-1455 feet.
• Dating Lower Permian conglomerates, reported at a total depth of 2081 feet, based on palynological examination of cores and cuttings.
• Comparing the age of coal measures to the Upper Coal Measures of the Sydney Basin as stated in the report's observations.

Strengths

• Report provides specific depth intervals for geological transitions, such as 1615-1645 feet for Lower Permian beds.
• Analysis correlates data from two distinct locations: the Wentworth well and the Oaklands-Coorabin coalfield.

Limitations

• Dataset consists of a textual report in PDF/HTML format without structured, machine-readable data columns.
• Sample data and row counts for fossil observations are unavailable, limiting quantitative analysis.
