Abstract

Lithium is a high-demand, critical element used not only in lightweight rechargeable lithium-ion batteries, but also in nuclear applications and industries producing ceramics, aluminum, and medical products. It is extracted primarily from pegmatites and volcano-sedimentary brines and clays in arid, closed lacustrine or caldera basins. Lithium brines of the central Andean salars in the AltiplanoPuna Plateau contain around ~70% of the world’s lithium resources. In contrast, Clayton Valley, Nevada is the only current producer of lithium brines in the United States and accounts for ~6% of current global lithium production. Clayton Valley hosts a newly defined Li-clay resource where locally exposed rhyolite tuffs have been proposed as a lithium source. Identifying magma evolution processes and determining the importance of syn- and post-eruptive processes on the source, mobility, and distribution of lithium is an ongoing area of research. These two regions illustrate distinctive magmatic-tectonic regimes for volcano-sedimentary lithium enrichment and therefore represent ideal regions to explore the key geological processes critical to the enrichment of lithium resources.
