Glass Chemistry of Eruption Deposits from Mexican Volcanoes, 700 ka

Electron microprobe glass chemistry data from explosive eruption deposits of Popocatépetl, Iztaccíhuatl and Tláloc-Telapón volcanoes in Central México. The dataset spans the last 700,000 years and is associated with a 2021 research paper published in the Journal of Volcanology and Geothermal Research. It originates from a NERC grant and is hosted by the British Geological Survey.

Use Cases

• Reconstructing eruption chronologies based on glass chemistry data spanning 700 ka.
• Analyzing magma composition and evolution for Popocatépetl, Iztaccíhuatl, and Tláloc-Telapón volcanoes.
• Correlating tephra layers across Central Mexico based on geochemical fingerprints.
• Calibrating or validating volcanic hazard models for the Mexico City region.

Strengths

• Covers a long temporal range of 700,000 years.
• Geographically focused on three major volcanoes near a densely populated area.
• Data is directly linked to a peer-reviewed publication, providing context and validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analyses.
• Description metadata is limited; actual data quality requires manual inspection after download.
