We here present the first comprehensive provenance study of Sahara Desert using a combination multiple proxies and state-of-the-art statistical analysis. Our dataset comprises 44 aeolian-dune samples, collected across region from 12°N (Nigeria) to 34°N (Tunisia) 33°E (Egypt) 16°W (Mauritania) characterized by bulk-petrography, heavy-mineral, detrital-zircon UPb geochronology analyses. A set too...

Proxy reconstructions from the mid-Holocene (MH: 6,000 years ago) indicate an intensification of West African Monsoon and a weakening South American Monsoon, primarily resulting orbitally-driven insolation changes. However, model studies that account for MH orbital configurations greenhouse gas concentrations can only partially reproduce these Most do not remarkable vegetation changes occurred ...
