Unraveling the Enigma of the Sahara's Star Dune

Researchers have used radar and other technologies to study a large star dune in eastern Morocco, uncovering details about its formation and development. The study, led by British researchers, used radar to examine the dune's structure and luminescence dating to estimate its age. The star dune is estimated to be about 13,000 years old and is moving at a rate of about 50 centimeters a year. Star dunes make up just 10 percent of all dunes in Earth's deserts and have also been observed on Mars and Saturn's moon Titan.

Unraveling the Enigma of the Sahara's Moving 'Star Dune'

A new study published in Scientific Reports reveals that the enormous star dune in Morocco's Erg Chebbi dune field formed in less than 1,000 years, defying expectations of its age. Using ground-penetrating radar and sand samples, researchers found that the dune is only 900 years old, with a history shaped by climate shifts in the Sahara. This discovery challenges the difficulty of identifying ancient star dunes and sheds light on the dynamic nature of desert landscapes.

Unveiling the Secrets of Morocco's Massive Mobile Star Dune

Scientists from Aberystwyth University and University of London have uncovered the age and movement patterns of a giant star dune in Morocco's Erg Chebbi sand sea, revealing that its base is 13,000 years old while the upper part formed in the last 1,000 years. The dune moves at a rate of about 50cm a year due to winds blowing in opposing directions, and luminescence dating techniques were used to determine its age. This research sheds light on the formation and movement of these natural wonders, with implications for infrastructure planning and understanding of past climates.
