摘要: 长江断裂带东延至镇江后并未终止,而是于镇江、扬中之间南移了约三十公里,展布于江苏江阴、沙洲、靖江、南通境内,于吕泗以北进入黄海。同时讨论了长江断裂带的属性,指出长江断裂带应是一条自晚中生代以来的现代大陆裂谷带。

Abstract: According to a large amount of data,the authors have demonstrated the extending to the east of the Yangtze fault zone and indicated that its continuation passes through Jiangyin,Shazhou,Jingjiang and Nanton of Jiangsu province and sea waters of southern Yellow Sea. Nature of the Yangtze fault zone is also discussed. The authors consider that the Yangtze fault zone has been a great modern continental rift zone since the Late Mesozoic,1500 km long and 40—80km wide (the rift valley basin is 10—25km wide). The zone here called Yangtze rift valley zone is typical of features of rift valley; for example,the depth of the rift zone is an elevated one of the mantle current zone,and the like. This,therefore,may serve as a mirror of the modern continental rift zone in the world.
