Tectonic Geomorphology of the Snowy Monaro Highlands in Australia

Neotectonic fault uplift rates exceeding 0.1 mm/yr have been quantified for Australia's highest mountain region. The dataset results from lidar-based digital elevation model interpretation, field investigations, and optically stimulated luminescence and cosmogenic radionuclide dating. Geoscience Australia Data published this research on 2026-05-19 to constrain the contribution of late Quaternary faulting to landscape evolution.

Use Cases

• Quantifying late Quaternary fault uplift rates based on lidar DEM interpretation and field investigations.
• Analyzing the correlation between neotectonic activity and topographic relief based on the described findings.
• Characterizing seismic hazard in intraplate regions based on evidence of episodic fault activity.
• Modeling landscape evolution of high-relief regions based on combined geochronological and geomorphic data.

Strengths

• Quantifies fault uplift rates exceeding 0.1 mm/yr for specific major faults.
• Integrates multiple data sources: lidar DEMs, field work, and two geochronological methods (OSL and CRN dating).
• Focuses on the Snowy Monaro region, which has the highest elevation and greatest relief in Australia.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific study region.
