Description
Zhengyao Liu and colleagues published an open sediment database in 2025 for a major Chinese desert. The Gurbantunggut Desert sits in the Junggar Basin of Central Asia. It is China's second-largest desert. Its fixed and semi-fixed dunes take branching, honeycomb, and mixed shapes. Yet broad grain-size data across dune types were scarce. The team sampled many zones and hundreds of sites. They collected well over a thousand surface and profile samples.
All samples followed standard field protocols. A laser instrument measured grain sizes after careful pretreatment. The data capture how sediment changes by dune type and slope position. They also show change with depth in profiles. The patterns reflect wind, sediment supply, and plant cover at work. The authors offer the dataset as a baseline for dune studies. It can support work on sand transport, climate effects, and desert monitoring.
