中文摘要 | 鹅掌河位于邛海南岸,在近15年来泥石流和洪水不断地将泥沙从鹅掌河带入邛海,在邛海底部大量淤积泥沙,形成一由南到北(长2km),由低到高(平均高2 m),由窄到宽(南岸宽200 m,北岸宽600 m)的水下堤,在邛海湖中连接鹅掌河河口堆积扇处还发现了的水下冲沟.湖底扇,水下堤和水下冲沟对于研究湖相和海相浊流沉积有一定的研究和应用价值.浊流特别是高浓度浊流在湖中的沉积模式研究对于湖底和海底地貌的变迁,湖盆和深海油气藏的发现都有一定的价值和意义. |
英文摘要 | Goose Foot River is located in the south of Qionghai Lake, Sichuan, China. Huge sediment was carried into Qionghai Lake by debris flows and floods of Goose Foot River in recent 15 years. The sediment deposited in the lake and formed an underwater levee in the lake. The underwater levee is 2km in length, 200m ( along south coast) to 600m (along north coast) in width and the average 2m in height. A channel was found in the lake in 2003 and it was connected with the fan of river. It will be helpful for the research of deposition in lake and deep sea. Research on turbidity currents, especially high density turbidity currents will have special meaning not only for the geomorphology of lake and deep sea, but also for the seeking the hydrocarbon in lake and deep sea. |
