Sr-Nd-Pb isotope ratios from potential aeolian dust sources in Patagonia, South America ...
Patagonia in South America is thought to be the largest source of aeolian dust to the Southern Hemisphere during the Late Pleistocene. This study uses Sr-Nd-Pb isotope ratios from 62 samples collected in Patagonia in southern South America to further constrain the Patagonia endmember. Samples collec...

Patagonia in South America is thought to be the largest source of aeolian dust to the Southern Hemisphere during the Late Pleistocene. This study uses Sr-Nd-Pb isotope ratios from 62 samples collected in Patagonia in southern South America to further constrain the Patagonia endmember. Samples collection focused on both glacial and non-glacial sediment samples, including a north to south transect east of the Andes focused in particular on glacial related materials. We also collected a north to south transect focused along the coast, on non-glacial materials.
