Lower Cretaceous Foraminifera from a Queensland Well, Great Artesian Basin

Southwestern Queensland's Great Artesian Basin is the location of the Phillips-Sunray Buckabie No.1 well, drilled to 9,070 feet. The report from Geoscience Australia details the examination of cuttings from 80 to 3,310 feet and three core samples to determine a Lower Cretaceous marine section. It was last updated on 2026-04-30.

Use Cases

• Determining biostratigraphic zones based on the first appearance of foraminiferal species mentioned in the description.
• Correlating lithological units with fossil assemblages from described well cuttings and cores.
• Reconstructing the paleoenvironment of the Lower Cretaceous Great Artesian Basin based on described foraminifera and Inoceramus prisms.

Strengths

• Report covers a specific depth interval from 80 to 3,310 feet, considered the base of the marine Lower Cretaceous.
• Examination includes cuttings and three specific core samples (Core 1, 3, and 8) at defined depths.
• Analysis is based on both lithology and the appearance of key fossil species like Inoceramus prisms.

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/HTML reports, not a structured, machine-readable format.
