摘要
西湖凹陷渐新统一中新统陆盆沉积发育了类型丰富的河道沉积 ,本文根据陆盆充填机制对盆地演化各阶段的控制作用 ,从沉积层序、沉积构造、岩性组合特征诸方面探讨了盆地演化过程的河道变迁特点。
Xihu Trough developed various channel deposits from Oligocene to Miocene.According to continental basin-fill mechanism influencing various stage of basin evolvement,depositional sequence,sedimentary structures and lithologic characters have been discussed to explain evolving path of channel type Oligocene to Miocene in XihuTrough.
