An interdisciplinary team including researchers from Leipzig University has analyzed an extensive collection of sand samples from so-called megaripple fields around the world and gained new insights into the composition of these sand waves. These could help settle debates about the mechanistic origin of some recently discovered enigmatic extraterrestrial sand structures and improve our ability to infer information about past weather and climate events from sediment records. The results of their investigations have just been published in Nature Communications.
