AusArray: Lithospheric Anisotropy Measurements Across Australia

Shear-wave splitting analysis of SKS phases from the AusArray national 2-degree deployment and permanent seismic stations provides insights into Australia's lithospheric structure. The data was presented at the 2025 Australasian Exploration Geoscience Conference (AEGC) and is provided by Geoscience Australia Data. The dataset was last updated on 2026-05-19.

Use Cases

• Mapping anisotropic variations across the continent based on SKS splitting measurements.
• Investigating past and present lithospheric deformation and mantle flow patterns.
• Correlating seismic anisotropy with surface and near-surface geological features.

Strengths

• Data is derived from the national-scale AusArray seismic network, likely providing broad continental coverage.
• Analysis is based on the shear-wave splitting method, which is sensitive to seismic anisotropy in the lithosphere.
• Findings were peer-reviewed and presented at a major regional geoscience conference (AEGC 2025).

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 AusArray station deployment.
