Palynological Report on South Pacific Pty Ltd (Birkhead) Well

Twenty-two samples from the S.P.L. No.1 (Birkhead) well suggest the Permian-Triassic boundary lies between 3600 and 3700 feet. The report indicates a marine influence during the Upper Permian and suggests a potentially older unit at 5000 feet. This dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Locate the Permian-Triassic boundary based on reported depth estimates between 3600 and 3700 feet.
• Analyze paleoenvironmental conditions based on the reported marine influence in Upper Permian strata.
• Investigate stratigraphic age uncertainty based on the description of no evidence for ages above 1900 feet and below 5035 feet.

Strengths

• Report is based on the examination of twenty-two samples.
• Provides specific depth estimates for a key geological boundary.
• Identifies a marine influence in the Upper Permian.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
