"Uncovering Ancient Mysteries: Sahara's 13,000-Year-Old Star Dune Dormancy"
Scientists have unraveled the mystery of the absence of star-shaped dunes from Earth’s geological history by dating a 13,000-year-old star dune in Morocco and discovering its rapid formation in the last thousand years. The study, published in Scientific Reports, used ground penetrating radar and luminescence dating techniques to reveal the dune's growth and history, shedding light on Earth's past climate changes and geological formations.
