摘　　要：怒江及怒江大断裂的形成时代迥然不同。根据怒江河谷及其两岸第四纪沉积物特征及测年资料,分析怒江的形成时代应是早更新世—中更新世;而怒江大断裂开始形成于加里东期。The formed age for the Nu River and the Nujiang large fracture is utter-1y different. Analyses indicate that the formed age for Nu River would be the early-mid Pleistocene, and the Nujiang fracture began to form in Cale-donian period based on the Nu River valley, Quaternary sediment characters on both banks and the dating data.
