周口坳陷古生界潜山的成因及分布规律探讨

Formation and Distribution of Paleozoic Buried Hills in Zhoukou Depression

周口坳陷发育有古生界潜山,古生界潜山的形成主要受构造运动的控制,燕山期、喜山期拉张应力场控制了古生界潜山的分布,印支期、燕山期挤压应力场主要使古生界潜山的内幕结构更加复杂化。大断裂控制古生界潜山的分布。周口坳陷主要发育北西和北东向的古生界潜山。

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.
