Data sets

Clay mineralogy, grain size, XRF geochemistry and Nd and Sr isotopes from the central Red Sea W. Ehrmann et al. https://doi.org/10.1594/PANGAEA.960352

Short summary

Climatic and associated hydrological changes controlled the aeolian versus fluvial transport processes and the composition of the sediments in the central Red Sea through the last ca. 200 kyr. We identify source areas of the mineral dust and pulses of fluvial discharge based on high-resolution grain size, clay mineral, and geochemical data, together with Nd and Sr isotope data. We provide a detailed reconstruction of changes in aridity/humidity.
