Brittle-Ductile Transition Depth Dataset for Planetary Lithospheres

16 data files containing model outputs for brittle-ductile transition depth as a function of planetary parameters. Calculations were performed with a MATLAB code by Bradford J. Foley, published alongside a 2021 paper in the Journal of Geophysical Research: Planets. The dataset includes variations for pore pressure conditions, strain rates, and material parameters.

Use Cases

• Modeling lithospheric thickness on exoplanets based on surface gravity and temperature parameters.
• Analyzing the influence of strain rate and pore pressure on brittle failure depth.
• Comparing tectonic regimes across different planetary bodies using the provided material parameter variations.

Strengths

• Dataset consists of 16 distinct data files, allowing for parameter sensitivity analysis.
• Files systematically vary key modeling assumptions: pore pressure (dry/wet), strain rate (4 values), and material parameters (p & q).
• Source code for the model generating the data is publicly available on Zenodo.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent from the provided metadata; field semantics must be inferred from the file format description.
• Last update date is unknown; freshness unverified.
