Geologists from China and three other Asian countries will start a joint scientific expedition through the Himalayas in the middle of next month, announced the Chinese Academy of Sciences (CAS) on Friday.

 

The 16-strong team will for the first time bring along scientists from China, India, Nepal and Bhutan, all of which the Himalayas extend through, to make a month-long comprehensive investigation into the ecosystem and economic development of the region.

 

It will also be a precious opportunity for Chinese scientists to conduct more research into the southern bend of the Himalayas, said Zhang Wenjing, chief scientist of the expedition team.

 

The Himalayas, the world's highest and youngest mountain belt, extends about 2,400 kilometers from east to west. The Qinghai-Tibet Plateau of China borders it to the north, while India, Nepal and Bhutan lie along the southern slope.

 

"We have done a lot of work about the northern bend in the past five decades. But, due to political reasons and difficult local conditions, we had little chance to learn about the other side of the mountains," said Zhang, an iceberg research expert, now working at the Chengdu-based Institute of Mountain Hazards and Environment under CAS.

 

The scientific trek will start from Lhasa, over the northern bend and through the southern, with a vertical distance of more than 5,000 meters in altitude.

 

In addition to comparing the geological structures of the two bends, the scientists also plan to research their different flora and fauna, icebergs and water systems.

 

Liu Jiaqi, a leading geologist in China, said the different sceneries of the two bends are "gorgeous," though he was only able to catch a glimpse of the southern bend in his previous several expeditions into the Himalayas.

 

"The northern slope is ice-covered, with little trace of life; but the southern bend is the opposite. It has a subtropical vein," said the CAS academician.

 

He added that the expedition will probably provide a key to the mystery of the rise of the Himalayas. "Evidence of plate movement lies only in the southern bend," Liu said.

 

The scientists will also try to analyze the impacts of the two different ecosystems upon the indigenous climate during the expedition.

 

Zhang said sociologists will also join them to study local culture, economy, religion and environmental protection practices.

 

The trek will result in a draft map of the geology and ecosystem of the Himalayas.
