Redox-Driven Mineral and Organic Associations in Jezero Crater, Mars 
Supplemental Information Bundle

Joel A. Hurowitz, Stony Brook University

This bundle contains supporting information for the manuscript:

"Redox-driven mineral and organic associations in Jezero Crater, Mars" 
(2025). J. A. Hurowitz, et al. Nature, 645, 332-340. 
doi:10.1038/s41586-025-09413-0.

This bundle contains the following collection:

data - Oxide and elemental concentrations for each PMC in select targets
       analyzed by the Mars 2020 PIXL instrument between sols 1180-1243.
       Concentrations (wt%) were determined for Na2O, MgO, Al2O3, SiO2, 
       P2O5, SO3, Cl, K2O, CaO, TiO2, Cr2O3, MnO, FeO-T, NiO, ZnO, and Br
       by PIXL's quantification software PIQUANT. Concentrations are 
       determined from detector A spectra (*_rqa_*.csv), detector B 
       spectra (*_rqb_*.csv), and the spectra from both detectors 
       summed together ("detectors combined"; *_rqc_*.csv). This 
       collection also contains lists of the PMCs composing various 
       regions of interest in each PIXL scan (*_pmc.csv). 

Each data product in this bundle is described by a PDS4 label in a separate 
file with the same name but with the extension XML. PDS4 labels are XML 
(eXtended Markup Language) files that conform to the PDS4 Information Model 
XML schema at https://pds.nasa.gov/pds4/schema/released/. They are best viewed 
in an XML-aware text editor, and may be used by software that can manipulate 
XML documents.

See this source for more information.
