Palynological Observations on Flaxman's Hill No. 1 Well in the Otway Basin

Thirty-four core samples from the Flaxman's Hill No. 1 well in the Otway Basin, Victoria, provided spores and pollen identifying the Cretaceous age of the Otway Group. The dataset, from Geoscience Australia, includes observations of microplankton, spores, and pollens intended for correlation with other wells and outcrop samples from the Otway Group. Problems arising from tentative correlations between geological groups are outlined, but no solutions are offered.

Use Cases

• Correlating Upper Cretaceous strata based on spore and pollen distributions mentioned in the description.
• Identifying the Cretaceous age of geological formations based on palynological observations.
• Comparing subsurface and outcrop samples of the Wangerrip Group as outlined in the description.
• Analyzing problems in correlating the Lower Cretaceous Merino Group with the Otway Group.

Strengths

• Includes 34 core samples from a specific well, providing a focused geological record.
• Contains observations intended for correlation with two other specific wells (Port Campbell No.1 and Belfast No.4).
• Examines both subsurface well samples and Cretaceous outcrop samples from the Otway Group.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF and HTML formats, which may require extraction for analysis.
