Abstract

The structures and geological history of the shelf of the East Siberian continental margin are considered on the basis of the interpretation of seismic data along with geological data. The main structural constituents of the East Siberian Sea that were formed under the Barremian–Aptian rifting processes are described: the New Siberian rift; the Mansky, North Melville, and Drumhead rifts in the north of the East Siberian Basin; as well as the Melville depression in the south. The rifts are considered in combination with volcanic zones and the main elevations (De Long, Wrangell, Kotelnich, and Baranov). It is assumed that the rifting thinned the crust of the Podvodnikov Basin to form a large midland sedimentary basin.

东西伯利亚大陆边缘的裂谷系统

摘要

在解释地震数据和地质数据的基础上，考虑了东西伯利亚大陆边缘陆架的结构和地质历史。西伯利亚东海裂谷是在巴雷米亚-阿普特裂谷过程中形成的，主要结构成分有：新西伯利亚裂谷；新西伯利亚裂谷；新西伯利亚裂谷；新西伯利亚裂谷；新西伯利亚裂谷。东西伯利亚盆地北部的曼斯基，北梅尔维尔和鼓黑头裂谷；以及南部的梅尔维尔（Melville）洼地。认为裂谷与火山岩带和主要高程（德隆，弗兰格尔，科特尔尼奇和巴拉诺夫）结合在一起。假定裂谷使Podvodnikov盆地的地壳变薄，形成了一个大型的中部沉积盆地。
