Wentworth No.1 Well: Palynological Stratigraphy of the Murray Basin

Palynological analysis of cores and cuttings from the A.O.G. Wentworth No.1 well in New South Wales defines the geological transition from Tertiary to Lower Cretaceous and probable Lower Permian sediments. The report correlates these findings with samples from the Oaklands-Coorabin coalfield, suggesting an age equivalence to the Upper Coal Measures of the Sydney Basin. This dataset provides a detailed stratigraphic column for a specific well location in the Murray Basin.

Use Cases

• [Stratigraphic correlation] based on palynological markers identified in well cuttings and cores.
• [Age determination of subsurface units] based on the reported transition depths (e.g., 1283-1335 feet).
• [Basin analysis] based on the correlation between the well data and the nearby Oaklands-Coorabin coalfield.
• [Lithological interpretation] based on described sediment types like marine sediments and conglomerates.

Strengths

• Provides specific depth intervals for geological transitions (e.g., 1615-1645 feet for Lower Permian).
• Correlates findings from a well with a separate coalfield area, adding regional context.
• Sourced from Geoscience Australia, a national geological survey organization.

Limitations

• The core dataset columns and structure are unknown, limiting direct analysis.
• Metadata for size, row count, license, and author is consistently missing across all platform entries.
• A factual conflict exists in the description regarding the Tertiary-Cretaceous transition depth ('either 1283-1335 feet or 140-1455 feet').
