This study investigates the potential of saline surface soils as a non-conventional source for lithium, a critical element for energy storage technologies. While soil salinization is a major challenge in arid regions, it also drives the mobilization and surface accumulation of highly soluble elements. We propose that elements like lithium (Li), sodium (Na), and strontium (Sr) can be transported from depth via capillary action and evaporation, forming detectable geochemical anomalies in surface layers.

To test this, a refined aqueous extraction protocol was developed to enhance the recovery of these mobile elements from challenging arid substrates like aridisols and sabkhas. The method was applied to 36 samples from the Arabian Peninsula, with analysis conducted via ICP-OES. All data were normalized to a dry-weight basis to ensure robust comparability between samples with differing moisture contents.

Our results identified significant lithium anomalies, with concentrations in some samples reaching 258% of the background mean. Strong positive correlations between Li-K (r=0.83) and Li-Mg (r=0.84) suggest their co-migration via saline groundwater. Crucially, lithium concentrations in sabkha soils were found to be up to twenty times higher than in typical aridisols, underscoring the critical role of local hydrology and moisture content in element enrichment.

The findings confirm that surface geochemistry in saline environments can serve as an effective indicator for subsurface mineral potential. The presented extraction technique offers a rapid and cost-effective tool for early-stage lithium prospecting, positioning saline soils as a promising frontier for sourcing strategic metals.
