济阳运动是济阳坳陷新生代发展演化过程中一次极为重要的构造变动，具有区域性、块断性和阶段性的特点。济阳运动的形成是深部岩石圈动力学过程在近地表构造的反映。在沙四段沉积末期随岩石圈之下的热异常逐渐加大，岩石圈热结构发生变化，有效弹性厚度逐渐降低，模拟结果认为降低幅度可达8km，岩石圈的变形机制由弹性变形向塑性蠕变转变，这一转变导致的盆地地形变化响应可能是济阳运动形成的重要动力学因素。  相似文献   

Petroleum System of the Fula Depression at the Muglad Basin in the Central African Fault Zone     

张亚敏  顾勤 《中国地质大学学报(英文版)》2011,(3)

Petroleum system theory has been used to study characteristics of the Fula depression in the Central African fault zone.In this system,deep lacustrine facies mudstone in the Abu Gabra For-mation of the Lower Cretaceous is a very good source rock,thick deltaic facies sandstone of the Abu Gabra Formation and fluvial facies sandstone of the Bentiu Formation are good reservoir beds,and the mudstone in the Upper Cretaceous Darfur Group is the regional cap rock.The oil search mode and fault block trap seal-off co...  相似文献
