Titre : New evidence of the Sahara’s age

ScienceDaily (September 23, 2019)

Résumé
The Sahara Desert is vast, generously dusty, and surprisingly shy about its age. New research looking into what appears to be dust that the Sahara blew over to the Canary Islands is providing the first direct evidence from dry land that the age of the Sahara matches that found in deep-sea sediments : at least 4.6 million years old.
