Geochemical data (Ca isotopes, Mg isotopes, C isotopes, O isotopes, Sr/Ca ratios, Mg/Ca ratios, and Mn/Ca ratios) from Cryogenian carbonate successions.

Figures with high-resolution

Major element and trace element data for mineral phases within peridotites from the Southwest Indian Ridge.

Atomic coordinates and vibrational frequencies from ab initio simulaitons of Cu complexes associated with birnessite.

This datafile includes the EPMA elemental compositions and NanoSIMS isotopic compositions that are also presented in our Supplementary Information.

Geochemistry of aeolian (wind-blown) materials from the McMurdo Dry Valleys, Antarctica. These materials were analyzed for major oxide, trace element, and rare earth element abundances. A three-component mixing model is also included to help delineate source contributions.

''AGG-RB-MJ-KW-RG-dataset'' contains the main dataset. The table is organized so that each row is a valley network entry. Columns include the valley name (if applicable), lat/long, network stream order, the fit parameters and their standard error, upper and lower confidence bounds, RMS, concavity index theta, and basin hydrology exponent c with upper and lower bounds. ''AGG-RB-MJ-KW-RG-Context'' contains the geological and geomorpohlogical context of each valley network. The table is organized so that each row is a valley network entry. Columns include the valley name (if applicable), lat/long, geological unit of incision, age of the terrain, Neukum timing of valley activity, concavity index and background concavity index (from Stepinski et al., 2004), and spatial relationships with other valleys.

This file includes the data of total dissolved iron and manganese concentrations and their size-partitioning along the western segment of the GEOTRACES GP16 transect.

Longitudinal profile data (distance along main stem in meters vs. elevation in meters) for all the valley networks used in the related manuscript 'Did Martian valley networks substantially modify the landscape?'. Refer to the 0 README.txt file for more information.

Data tables 1 and 2 to accompany Joy et al. Bench Crater manuscript.
