Our colleague Mar Benavides sent us a nice paper about the composition and age of dust in Northwest Africa by Eglinton et al. Thank you very much. Below is the abstract. The paper is available on request and it is of interest for those working on the geology and chemistry of dust.
The introduction of the paper is really very original as they quote the first description of the dust clouds from the Sahara. The citation is from somebody named Charles Darwin who sail this area on board a ship called H.M.S. Beagle. Below is the text.
Nice description, like in a blog.
