Flaxman's Hill No. 1 Well: Palynological Observations on Cretaceous Otway Basin Cores

Thirty-four core samples from the Flaxman's Hill No.1 well in the Otway Basin, Victoria, were analyzed for spores, pollens, and microplankton. The data, provided by Geoscience Australia, identifies the Cretaceous age of the Otway Group and notes microfossils for potential correlation with other wells in the basin. The description also outlines unresolved correlation problems between Lower Cretaceous groups and subsurface-outcrop relations.

Use Cases

• Correlating Upper Cretaceous strata based on spore and pollen distributions mentioned in the description.
• Dating geological formations in the Otway Basin using identified Cretaceous microfossils.
• Studying paleoenvironmental conditions from the composition of microplankton and spores.
• Comparing subsurface well data with outcrop samples from the Wangerrip Group as outlined.

Strengths

• Thirty-four core samples provide a specific basis for analysis.
• Data is tied to a specific, named well (Flaxman's Hill No.1) and geographic basin (Otway).
• Analysis includes comparison with two other specific wells (Port Campbell No.1, Belfast No.4) for correlation.

Limitations

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