Luminescence characteristics of surface sediments from southern South America

This dataset contains locations and luminescence measurements for individual surface sediment samples collected across southern South America, including corresponding relative standard errors for each sample. The measurements comprise feldspar luminescence signals used to characterize signal properties and variability among samples. Sampling locations span a range of geomorphological and climatic settings in southern South America. The purpose of the dataset is to support the analysis of sediment provenance and transport processes using luminescence characteristics of surface sediments.
