Abstract
Svalbard has long been thought to represent the easternmost realm of the Ellesmerian Orogeny in the late Devonian or early Mississippian (Svalbardian tectonic event). Several authors do not agree and present alternative interpretations of the observed structures in older and more recent articles. This article discusses a number of issues that, in our opinion, are not sufficiently considered in those works, but which are essential for the understanding of the Svalbardian tectonic event: (1) the possibility of re-deposited palynomorphs in the discussion of the deformational ages, (2) the age and structural setting of the crucial Adriabukta Formation in southern Spitsbergen, and (3) the presence and nature of the Svalbardian angular unconformity in central and southern Spitsbergen.
期刊介绍：
Since 1982, Polar Research has been the international, peer-reviewed journal of the Norwegian Polar Institute, Norway''s central institution for research, environmental monitoring and mapping of the polar regions. Aiming to promote the exchange of scientific knowledge about the Arctic and Antarctic across disciplinary boundaries, Polar Research serves an international community of researchers and managers. As an open-access journal, Polar Research makes its contents freely available to the general public.
Original primary research papers comprise the mainstay of Polar Research. Review articles, brief research notes, letters to the editor and book reviews are also included. Special issues are published from time to time.
The scope of Polar Research encompasses research in all scientific disciplines relevant to the polar regions. These include, but are not limited to, the subfields of biology, ecology, geology, oceanography, glaciology and atmospheric science. Submissions from the social sciences and those focusing on polar management and policy issues are welcome. Contributions about Antarctica are particularly encouraged.
