Palynological Report on S.P.L. No.1 (Birkhead) Well

An examination of twenty-two samples from the S.P.L. No.1 (Birkhead) well suggests the Permian-Triassic boundary lies between 3600 and 3700 feet. The report indicates a marine influence in Upper Permian times and a possibly older unit at 5000 feet. It was published by the Australian Ocean Data Network and last updated on 2026-04-16.

Use Cases

• Identify the Permian-Triassic boundary based on palynological analysis of well cuttings.
• Investigate marine influence in Upper Permian strata using microfossil evidence.
• Analyze stratigraphic units and their relative ages from well sample depths.

Strengths

• Analysis is based on twenty-two physical samples from a specific well.
• Provides depth-specific interpretations, including a boundary between 3600-3700 feet and a unit at 5000 feet.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
