Abstract

A new seismostratigraphic model was developed for the sedimentary cover of the North-Chukchi Basin and the main paleogeographic events that occurred within this territory were interpreted. The post-rift sedimentary history of the North-Chukchi basin can be divided into three stages: the late Cretaceous–Paleocene with strong progradation of shelf sedimentary packages to the north, the middle Eocene–Miocene with gradual differently oriented filling of the basin from different sides, and the late Miocene until the present. At the last stage, the shelf outlines were formed along with slow aggradation of the clinoform complex with an insignificant northern deviation.

北楚科奇盆地（楚科奇海，北极）的新生代斜形复合体和地质历史

摘要

为北楚科奇盆地的沉积盖层开发了一种新的地层学模型，并解释了该领土内发生的主要古地理事件。北楚科奇盆地裂谷后的沉积历史可分为三个阶段：白垩纪晚期至古新世晚期向北沉积了陆架沉积物；中新世中期至中新世以来盆地沉积逐渐不同。双方，直到中新世晚期。在最后阶段，架子轮廓是随着斜形复杂物缓慢凝结而形成的，北部偏距不明显。
