Parsons et al 2021: Seismic Tomography and Restored Eurasian Margin Data

Parsons et al 2021 - Supporting Data comprises seismic tomography data and a shapefile of a restored Eurasian continental margin. The data were collected via the SubMachine web app and processed using ArcMap and Adobe Illustrator. This dataset supports the accompanying manuscript by Andrew J. Parsons from the University of Oxford, published in Geophysical Research Letters.

Use Cases

• Modeling seismic velocity structures based on the described tomography data.
• Reconstructing paleogeographic maps using the 43 Ma Eurasian margin shapefile.
• Validating geodynamic models against the restored continental margin geometry.
• Producing publication-quality figures of seismic tomography results.

Strengths

• Data is linked to a peer-reviewed manuscript in Geophysical Research Letters, providing academic context.
• The shapefile provides a specific geological reconstruction for a defined time (43 Ma).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
