Formation and Distribution of Paleozoic Buried Hills in Zhoukou Depression

Buried hills of Paleozoic developes in Zhoukou depression .The formation of Paleozoic buried hills is mainly controlled by tectonic movements. The distribution of buried hills is controlled by the stressed field of stretching during Yanshan and Himalayan period ,and the stressed field of compressing during indosinian and Yanshan period mainly makes the inside structure of paleozoic buried hills more complex .The distribution of paleozoic buried hills is controlled by regional fault. Paleozoic buried hills of NW , NE trending developes well in Zhoukou depression.
