The US Appalachian Basin and the Arctic Norwegian and Russian Barents Sea shelf (BSS) areas are two strategic provinces for the energy industry. The Appalachian Basin is a well-studied, mature, onshore basin, whereas the offshore BSS is still considered a frontier area. This study suggests that the Appalachian Basin may be an appropriate analogue for understanding the BSS and contribute to development of a tectonostratigraphic framework for the area. Although the Appalachian and BSS areas reflect different times and settings, both areas began as passive margins that were subsequently subjected to subduction and continent collision associated with the closure of an adjacent ocean basin. As a result, both areas exhibited multi-phase subduction-type orogenies, a rising hinterland that sourced sediments, and a foreland-basin sedimentary system that periodically overflowed onto an adjacent intracratonic area of basins and platforms with underlying basement structures. Foreland-basin sedimentary systems in the Mid-to-Late Palaeozoic Appalachian Basin are composed of unconformity-bound cycles related to specific orogenic pulses called tectophases. Each tectophase gave rise to a distinct sequence of lithologies related to flexural events in the orogen. In this study, similar sequences are recognised in both BSS foreland-basin and adjacent intracratonic sedimentary sequences that formed in response to the Late Palaeozoic–Mesozoic Uralian–Pai–Khoi–Novaya Zemlya Orogeny, suggesting that the processes generating the sequences are analogous to the tectophase cycles in the Appalachian Basin. Hence, this pioneering use of the Appalachian area and its succession as large-scale tectonostratigraphic analogues for the BSS may further enhance understanding of Upper Palaeozoic to Middle Jurassic stratigraphy across the BSS.

阿巴拉契亚地区作为巴伦支海陆架的构造地层类似物

美国阿巴拉契亚盆地和北极挪威和俄罗斯巴伦支海陆架 (BSS) 地区是能源行业的两个战略省份。阿巴拉契亚盆地是一个经过充分研究的成熟陆上盆地，而海上 BSS 仍被视为前沿地区。这项研究表明，阿巴拉契亚盆地可能是理解 BSS 的适当类比，并有助于开发该地区的构造地层框架。尽管阿巴拉契亚和 BSS 地区反映了不同的时间和环境，但这两个地区开始时都是被动边缘，随后经历了与邻近海洋盆地关闭相关的俯冲和大陆碰撞。结果，这两个地区都表现出多期俯冲型造山运动，一个上升的腹地，沉积物，和一个前陆盆地沉积系统，周期性地溢出到相邻的克拉通内盆地和具有下伏基底结构的台地区域。中-晚古生代阿巴拉契亚盆地的前陆盆地沉积系统由与称为构造相的特定造山脉冲相关的不整合旋回组成。每个构造阶段都产生了与造山带中的弯曲事件相关的不同岩性序列。在这项研究中，在响应晚古生代-中生代乌拉尔-拜-科伊-新地岛造山运动而形成的 BSS 前陆盆地和相邻的克拉通内沉积序列中都发现了类似的层序，这表明产生这些层序的过程类似于阿巴拉契亚盆地的构造相旋回。因此，
