Réunion and Mauritius Volcanic Geology with Elevation Models and Chronostratigraphy

Vincent Famin's dataset supports the article 'Synchronized Mascarene volcanism reveals 400 kyr cycles in melt supply from the Réunion plume'. It contains geological maps for Réunion and Mauritius in QGIS format, including digital elevation models and geochronological data, plus six supplementary Excel tables. The 156.9 MB dataset was last updated on April 15, 2026.

Use Cases

• Analyzing volcanic stratigraphy and eruption cycles based on the provided geological units and chronostratigraphy.
• Modeling terrain and volcanic features using the 5m and 30m resolution digital elevation models.
• Correlating geochronological data between Réunion and Mauritius islands to study synchronized volcanism.
• Conducting spatial analysis of volcanic units and geological structures using the provided QGIS map files.

Strengths

• Includes high-resolution (5m) digital elevation model data for Réunion Island.
• Contains six supplementary Excel tables (S1-S6) with structured supporting data.
• Geological units are defined according to a specific volcanic chronostratigraphy, providing a consistent framework.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some analyses.
• The dataset's 156.9 MB size and multiple file formats (TIF, SHP, XLSX, etc.) may require specific software for full utilization.
