Sr, Nd and Pb isotope characterisation of surface sediment samples from playa lakes in the Mojave Desert

Strontium, neodymium and lead isotopic signatures were measured on a suite of surface sediment samples from nine different playa lakes across the Mojave Desert. All sediment samples had carbonates and organic material removed before full chemical digestion prior to analysis. Ferromanganese coatings were also removed in a subset of samples, with no notable isotopic effect from an anthropogenic contribution of Pb detected.
