WebJul 12, 2012 · Clay and fine-silt grains and aggregates are scarce in sand dunes, which most likely produce dust particles through aeolian abrasion of sand grains. Thus, saltating sand grains impacting clay aggregates on playa surfaces cannot be the sole process for generating dust in the Sahara. Key Points WebJan 24, 2014 · Glacial dust recorded in ice cores from the East Antarctic Plateau originates almost exclusively from South America, including Patagonia ().Model simulations have supported this view and have suggested that dust deposition in the SO occurs mainly in the Atlantic and western Indian SO sectors.However, a recent simulation indicates that …
