China is building a national geological park of yellow earth for scientific research and educational purposes in its northwest province of Shaanxi.
Located in Heimugou of Luochuan County, the 5.9-square kilometer park on China's Loess Plateau is home to a variety of yellow earth terrains.
Geologists said studying its yellow earth plane sections could reveal climatic, environmental and botanic changes in the Loess Plateau over the past 2.5 million years.
Covering 640,000 square kilometers in six provinces, the Loess Plateau is believed to be an origin of the Chinese nation.
