AbstractA new collection of papers spanning the breadth of the Arctic provides new insight into the region's geodynamic evolution. New results pertain to lithospheric structure, the interconnection between magmatic and extension-related tectonic processes, variations in the lower crustal compositions of the Amerasian Basin, based on seismic velocity and potential field responses, and provenance and paleogeography of Paleozoic to Triassic successions across the Arctic. Elucidation of geodynamic processes in the Eurasian Basin provides lessons for future reseach in the complex and poorly understood Amerasian Basin. New results detrital zircon provenance studies as well as stratigraphic facies compilations constrain the Late Paleozoic paleogeography of the Arctic realm.
Summary(Plain Language Summary, not published)
This publication is an overview and summary of the contents of a Tectonophysics Special Issue, which the authors of the current paper are editing. It summarizes the conclusions of 15 research papers covering diverse topics on the geological history of the Arctic. It reflects on the new results and discusses how the well-understood modern plate tectonic processes currently active can inform future work in adjacent areas where these processes are no longer active.
