Traditionally active rifts are thought to evolve in response to thermal upwelling of the
asthenosphere, whereas passive rifts develop in response to lithospheric extension driven …

Abstract The Wilson Cycle theory that oceans close and reopen along the former suture is a
fundamental concept in plate tectonics. It was named after J. Tuzo Wilson who recognised …

We present a new model of the crustal and tectonic structure of the Arctic region north of 60°
N latitude, constrained as a part of the international Atlas of Geological Maps of the …

The tectonic evolution of the circum-Arctic, including the northern Pacific, Siberian and North
American margins, since the Jurassic has been punctuated by the opening and closing of …

New U-Pb geochronology and a large and growing geochemical data base has clarified the
age and composition of the extensive magmatic belts of NE Russia, allowing a better …

The history of the 2.5 million km2 Amerasia Basin (sensu lato) is in many ways the least
known in the global tectonic system. Radically different hypotheses proposed to explain its …

This article reviews the characteristics of Arctic lithosphere and the principal tectonic events
which have shaped it. The current state-of-knowledge associated with the crust, crustal …

Abstract The Alpha–Mendeleev ridge complex is a first-order physiographic and geological
feature of the Arctic Amerasia Basin. High amplitude “chaotic” magnetic anomalies (the High …

A seismic stratigraphic framework and basin fill geohistory for Arctic Ocean basins is
presented based on data collected by several Russian Government organized expeditions …

In this study, we identify a giant circumferential mafic dyke swarm associated with the 135–
75 Ma High Arctic Large Igneous Province (HALIP). Previously, a HALIP giant radiating …
