New research has found the first evidence that large rivers control desert sands and dust in Northern China.

The results from study showed that the Yellow River transports large quantities of sediment from northern Tibet to the Mu Us desert and further suggests that the river contributes a significant volume of material to the Loess Plateau.

New research published today in the journal Quaternary Science Reviews has found the first evidence that large rivers control desert sands and dust in Northern China.

Northern China holds some of the world's most significant wind-blown dust deposits, known as loess. The origin of this loess-forming dust and its relationship to sand has previously been the subject of considerable debate.

The team of researchers led by Royal Holloway University, analysed individual grains of fine wind-blown dust deposited in the Chinese Loess Plateau that has formed thick deposits over the past 2.5 million years. As part of this, they also analysed the Mu Us desert in Inner Mongolia and the Yellow River, one of the world's longest rivers, to identify links between the dust deposits and nearby deserts and rivers.

The results showed that the Yellow River transports large quantities of sediment from northern Tibet to the Mu Us desert and further suggests that the river contributes a significant volume of material to the Loess Plateau.

"The Yellow River drains the northeast Tibetan plateau and so the uplift of this region and the development of Yellow River drainage seems to control the large scale dust deposits and sand formation in this part of China," said lead researcher Tom Stevens from the Department of Geography at Royal Holloway.

"Identifying how this dust is formed and controlled is important, since it drives climate change and ocean productivity and impacts human health. Its relationship to the river and Tibet implies strong links between tectonics and climate change. This suggests that global climate change caused by atmospheric dust may be influenced by the uplift of Tibet and changes in major river systems that drain this area."
