Lithospheric Thickness Estimates for Global CO2-Rich Magma Distribution

72.7 KB of lithospheric thickness estimates calculated for spatially averaged magma types. The data, created by Emilie Bowman and last updated on May 23, 2026, defines the mechanical lithosphere-asthenosphere boundary using either the 1290°C or 1175°C isotherm.

Use Cases

• Modeling global CO2 flux from magmatic sources based on lithospheric thickness.
• Analyzing correlations between lithospheric structure and magma geochemistry.
• Validating geodynamic models of the lithosphere-asthenosphere boundary using isotherm definitions.

Strengths

• Data is openly licensed under CC-BY-4.0.
• Lithospheric thickness is calculated using two distinct isotherm definitions (1290°C and 1175°C), allowing for methodological comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 72.7 KB size suggests a limited scope, likely containing summary or point data rather than high-resolution grids.
