Geological Revisions for Hay River, Huckitta, and Tobermory Sheets

Northern Territory geological mapping corrections and additions for the Huckitta, Hay River, and Tobermory Four-mile Sheets. The report presents water bore data and details stratigraphic revisions, including measured sections up to 3,200 feet thick and fossil discoveries. It was published by Geoscience Australia Data.

Use Cases

• Correcting regional geological maps based on revised stratigraphic correlations and fault interpretations.
• Analyzing depositional environments based on measured sections and fossil assemblages mentioned in the description.
• Studying structural geology based on described fault zones like the Toomba Structure with throws exceeding 2,000 feet.
• Dating geological units based on described fossil evidence, such as trilobites indicating Cambrian age or plant fossils suggesting Triassic/Jurassic age.

Strengths

• Includes specific stratigraphic thickness measurements, such as the Arrinthrunga Formation being about 3,200 feet thick.
• Reports detailed fossil discoveries, including trilobites and brachiopods at specific horizons.
• Describes structural features with quantified metrics, such as a fault with a maximum throw exceeding 2,000 feet.

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 bias inherent to the specific mapped sheets in the Northern Territory.
