Palynological Report on the Birkhead Well: Permian-Triassic Boundary Analysis

Twenty-two samples from the S.P.L. No.1 (Birkhead) well were examined to analyze subsurface geology. The report suggests the Permian-Triassic boundary lies between 3600 and 3700 feet and indicates a marine influence during the Upper Permian. This palynological analysis was published by the Australian Ocean Data Network.

Use Cases

• Identify the Permian-Triassic boundary depth based on microfossil evidence.
• Analyze paleoenvironmental conditions, such as marine influence, during the Upper Permian.
• Correlate stratigraphic units in the South Pacific region using palynological data.

Strengths

• Report is based on the analysis of twenty-two specific samples.
• Provides depth estimates for a major geological boundary (3600-3700 feet).
• Identifies specific geological periods and environmental influences (Upper Permian, marine).

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.
