摘要

摘要: 北淮阳构造带由一系列向北逆冲推覆的构造岩片组成,是建立大别山造山带和合肥盆地构造关系的纽带,先后经过燕山早期和燕山晚期两次向北逆冲推覆作用。燕山早期的构造以后缘滑脱、前缘推覆为特征;燕山晚期逆冲推覆构造以区域挤压、向北逆冲为特征。合肥盆地经过坳陷、断陷两大阶段的沉陷。合肥盆地的坳陷形成强烈受到扬子陆块基底持续俯冲和大别山隆起的控制,晚白垩世后的断陷明显受到大别山差异隆起的影响,并表现出良好的构造耦合关系。合肥盆地东南的舒城坳陷是进一步寻找油气的构造有利地区。

Abstract: The North Huaiyang Structural Belt is composed of a series of thrust slices up to north, and is the transitional zone between the Dabieshan Orogenic Belt and the Hefei Basin. It underwent two generations of thrusting of the Early Yanshanian and the Late Yanshanian. The Early Yanshanian structure is characterized by back detachementing and front thrusting, and the Late Yanshanian one is expressed by regional extruding and thrusting up to north. The Hefei Basin underwent two generations of subsidence including depressions and faulted sags. The depression is controlled by uplifting of the Dabieshan Mountain caused by subducting of the basement of the Yangtze Continental Block, and the faulted sag is affected by the divergence uplifting. They show a good tectonic coupling relationship. The Shucheng Depression in the southeastern part of the Hefei Basin is a tectonic favorable area for oil and gas exploration.
