The mountains are like shells and the scenery is very good.

The scenery is very good, the mountains are like shells.

It is not unusual to see shells on the seaside. It is a bit strange to see shells that should have appeared on the Qinghai-Tibet Plateau, and it is still a large area. There is such a shell in the wilderness of Dulan County, Qaidam Basin, Qinghai. The locals are called shell beams. Shell beams can only be regarded as a small hillside, about 2 kilometers long, 70 meters wide, covered with hundreds of millions of shells large and small. The shell surface is covered with thin saline soil layer, and it has been dug 20 meters down after excavation, which is a shell accumulation layer. This is the largest paleontological formation found in China's inland basins so far. These shells, large in the size of copper money, small in the size of thumb, mixed with the sand of saline land, look at the white, and look at the near is still very spectacular. According to geologists, the Qaidam Basin area was still a sea, the Guttis Sea, a hundred million years ago. Later orogeny of the seabed rose to a plateau, and some people speculated that the shells were left behind. But local geologists in Qinghai denied this, and their research shows that the shell beams formed about 150,000 years ago, and the shells are not different from the current shells, and they are not left in ancient times. Although no definitive study has yet been done to confirm the origin of these shells, the geological changes in the vicissitudes of the sea are indisputable, and this place was definitely a place where the water and grass were abundant before.
