3. zone

Wuxi City, Wuxi City is dominated by plains, with scattered low mountains and residual hills. The south is the plain of water network; North high sand plain; The middle part is a water network polder field composed of lowlands; Southwest is a high-lying area with low mountains and hills in Yixing. The prototype of Wuxi landform was formed in the Cathaysian structure in Indosinian period (about 65.438+0.8 billion years ago), which made Wuxi area fold into land. The Yanshan movement (about 65.438+0.5 billion to 70 million years ago) was due to strong volcanic activity, which formed a new fold structure and made the originally stable basement regenerate and uplift. About 25 million years ago, the Himalayan movement was dominated by differential ups and downs. On the basis of the old structure, the folds and faults in the east-west direction have been strengthened, and a depression basin centered on modern Taihu Lake, namely Taihu Basin, has been formed in the east of Jiangyin and Yixing.
