We thank Richard Reynolds and an anonymous reviewer for the helpful comments and suggestions to improve the manuscript.

The field campaign and its associated research, including this work, were funded by the European Research Council under the Horizon 2020 Research and Innovation programme through the ERC Consolidator Grant FRAGMENT (grant agreement no. 773051) and the AXA Research Fund through the AXA Chair on Sand and Dust Storms at BSC. Cristina González-Flórez was supported by a PhD fellowship from the Agència de Gestió d'Ajuts Universitaris i de Recerca (AGAUR) grant 2020_FI B 00678. Konrad Kandler was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation, grant nos. 264907654 and 416816480). Martina Klose received funding through the Helmholtz Association's Initiative and Networking Fund (grant agreement no. VH-NG-1533). We acknowledge the EMIT project, which is supported by the NASA Earth Venture Instrument program, under the Earth Science Division of the Science Mission Directorate. We are grateful to Claire Blaske and Sahil Azad for assistance with sampling in the Mojave National Preserve. Samples within the preserve were collected under permit MOJA-2022-SCI-0034. We thank Rose Pettiette at the BLM office in Needles, CA, for advice and for allowing sampling on BLM land. We thank Jason Wallace and Anne Kelly from CSU Desert Studies Center at Zzyzx for their support during the campaign. Bethany L. Ehlmann, Rebecca N. Greenberger, and Abigail M. Keebler thank the Resnick Sustainability Institute at Caltech for partial support. Without all of the people mentioned, the sampling campaign would not have been successfully feasible.

The article processing charges for this open-access publication were covered by the CSIC Open Access Publication Support Initiative through its Unit of Information Resources for Research (URICI).

Contributions

Sample permits were obtained by BLE, RNG, and AMK. The samples were collected by CPGP, AGR, AMK, RNG, and XQ and analysed by AGR, MHC, and NM. EMIT mineralogy maps we produced by RG, PB, and RNC. PG provided the FoO map. AGR analysed the data and wrote of the original draft manuscript, supervised by CPGP and XQ. CPGP and XQ re-edited the manuscript and all authors contributed to data discussion, review, and paper finalization.
