Carboniferous Faunal Correlation Chart for Australian Marine Basins

A correlation chart synthesizing evidence from Carboniferous marine faunas across Australia. The chart is based on biostratigraphic scales using conodont, foraminifer, and brachiopod zones from Western Australian intracratonic basins and the New England Geosyncline in eastern Australia. It was published by the Australian Ocean Data Network and last updated on 2026-04-16.

Use Cases

• Correlating Lower Carboniferous marine sequences based on conodont and brachiopod zones mentioned in the description.
• Dating geological formations using biostratigraphic scales referenced from Britain, Belgium, and Germany.
• Comparing faunal sequences between the Bonaparte Gulf Basin and the New England Geosyncline as described.
• Making tentative correlations of terrestrial sequences based on plant and spore evidence as noted in the synopsis.

Strengths

• Chart is based on established biostratigraphic scales from multiple international regions (Britain, Belgium, Germany).
• Covers distinct geological provinces in Australia (Western Australian basins and eastern New England Geosyncline).
• Last updated date is provided (2026-04-16).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Correlation of terrestrial sequences is described as 'highly tentative' due to sporadic evidence.
