Evaluation of the regional geotectonic impact of the High Arctic Large Igneous Province (HALIP) in the present‐day northern Atlantic region has been hindered by poor correlation between the Svalbard–Barents Shelf region and eastern North Greenland. New sedimentological and biostratigraphic data from Peary Land and Kronprins Christian Land (Kilen), North Greenland reveal that the Lower Cretaceous palaeogeographic and sequence stratigraphic development of this area is closely comparable to that of Svalbard. The succession records Hauterivian – early Barremian regional uplift and emergence followed by fluvial sedimentation and subsequent transgression in the late Barremian – early Aptian. Recognition of this tectonically forced regression in North Greenland provides a link to a coeval well‐known tectonostratigraphic event in the Svalbard region, and hence to regional tectono‐magmatic uplift heralding the HALIP and the initiation of the Amerasia Basin.

北极白垩纪早期构造-岩浆隆升的区域影响:北格陵兰东部新数据的含意

斯瓦尔巴特-巴伦支大陆架地区与北格陵兰东部地区之间的相关性较弱,阻碍了对当今北极北部高火成岩省(HALIP)区域地质构造影响的评估。来自北格陵兰岛Peary Land和Kronprins Christian Land(Kilen)的新沉积学和生物地层学数据表明,该地区的下白垩纪古地理和层序地层发育与斯瓦尔巴特群岛具有可比性。演替记录了上特世–巴里米亚早期的区域隆升和出现,随后是河流沉积和随后在巴里米亚– Aptian早期的海侵。对北格陵兰北部这种构造强迫回归的认识提供了与斯瓦尔巴特地区同一时期著名的构造地层事件的联系,
