| 摘 要： | 西湖凹陷裂陷期构造主要是指从断陷开始形成(Tg界面)至始新世末(T30界面)的构造,它控制着盆内裂陷期地层的发育和沉积体系的总体展布特征.裂陷期原盆地的构造格架总体为一复杂的半地堑结构,主要受控于三组NE向的断裂带:东缘陡坡断裂带、中央洼陷断裂带、西部缓斜坡断裂带.西湖凹陷裂陷期古构造格局对裂陷期构造层序沉积、沉降中心...

| Abstract: | The structures of the Xihu Sag in the rifting stage include those formed from the onset of rifting(boundary Tg) up to the Late Eocene(Boundary T 30)in this paper.The Structural pattern is the factor controlling over the development of stratigraphy and the spatial distribution of depositional systems.The prototype of the basin during the rifting stage is a complicated half graben controlled by three groups of fault zone,i.e.the fault zone on east steep slope,the fault zone in central depression,and the fault... |
