geographical environment

The geological structure of Xi city spans the Qinling geosyncline fold belt and the North China platform. During the Yanshan Movement about 654.38+300 million years ago, a large fault occurred across the northern foot of Qinling Mountains. Since the Neogene about 3 million years ago, the neotectonic movement in the Qinling geosyncline fold belt south of the great fault has been extremely active, and the mountains in the north have fallen sharply, which has created the Qinling Mountains. At the same time, the Weihe fault, which belongs to the North China Platform to the north of the great fault, continues to sink.

The altitude difference in Xi 'an ranks first among cities in China. The Qinling Mountains, which are towering and steep with competing peaks, have clear boundaries with the open and flat Weihe Plain, which constitutes the main landform of Xi 'an. The main peak of Qinling Mountain is 2000-2800 meters above sea level, of which the main peak of Taibai Mountain at the southwest end is 3867 meters above sea level, which is the highest peak in the central mainland.
