Palaeogeographic Maps of Northern Australian Plate Margins

Updated reconstructions cover tectonic phases from the Carboniferous to the Holocene. The Australian Ocean Data Network published this report incorporating new plate models for the northern margins of the Australian plate. The study was last updated in April 2026.

Use Cases

• Model tectonic evolution using the described Carboniferous to Sakmarian pre-breakup phase features.
• Analyze sedimentation patterns from the deltaic clastic sedimentation phase following Meso-Tethys breakup.
• Study plate boundary changes using reconstructions of the Greater Birds Head microplate's rotation.
• Map geological history through the described phases of rift basin formation and passive margin development.

Strengths

• Covers a long temporal range from Carboniferous to Holocene.
• Incorporates multiple alternative tectonic reconstructions.
• Focuses on the complex northern margins of the Australian plate.

Limitations

• Specific data volume, row count, and sample size are unknown.
• The report notes many tectonic models are difficult to substantiate with available data.
• Data is presented in report formats (HTML, PDF), not as structured numerical datasets.
