Lower Cretaceous Foraminifera from a Queensland Well Core and Cuttings

A 2026 report from Geoscience Australia details a paleontological study of the Lower Cretaceous marine section in southwestern Queensland. The analysis is based on well cuttings from 80 to 3,310 feet and three specific core samples from the Phillips-Sunray Buckabie No.1 well, drilled to 9,070 feet. It uses lithology and the first appearance of foraminiferal species and Inoceramus prisms to define the sequence.

Use Cases

• Stratigraphic correlation based on the first appearance of foraminiferal species.
• Reconstructing paleoenvironments based on lithology and microfossil assemblages.
• Dating geological sequences using Inoceramus prisms mentioned in the description.

Strengths

• Analysis covers a significant depth interval from 80 to 3,310 feet.
• Includes data from three specific core samples, providing detailed point-information.
• Report is sourced from Geoscience Australia, a national geological authority.

Limitations

• The dataset is described in a report format (PDF/HTML); the underlying structured data is not directly accessible.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
