Description

Dataset for paper: Byrne et al. (2021) The Effects of Planetary and Stellar Parameters on Brittle Lithospheric Thickness, J. Geophys. Res. Planets

Dataset consists of 16 data files. Each data file gives brittle-ductile transition depth as a function of surface gravity, surface temperature, mantle temperature, and lithosphere thickness. Calculations were performed with a MATLAB code, available at Foley (2021) Brittle-ductile transition code. Zenodo. https://doi.org/10.5281/zenodo.5560138. 

The file format is as follows-Column1: surface gravity in m/s2; Column 2: surface temperature in K; Column 3: effective cooling age of the lithosphere in Myrs; Column 4: mantle temperature in K; Column 5: surface heat flux in mW/m2; Column 6: Total lithosphere thickness in km; Column 7: Brittle-ductile transition depth in km 

File names denote additional parameters. All file names give as lowTplas_dry_... assume pore pressure on faults is 0, while files with names lowTplas_wet_... assume hydrostatic pore pressure. The values of the parameters p & q are given in the file names as _p12q2_ for models where p=0.5 and q=2, and _p1q2_ for models where p=1 and q=2. Finally, the assumed strain rate is appended at the end of the file names as _e1e-13 for strain rate = 10-13 1/s, _e1e-14 for strain rate = 10-14 1/s, _e1e-15 for strain rate = 10-15 1/s, and _e1e-16 for strain rate = 10-16 1/s.
