Fourteen chapters discuss regional stratigraphy by time intervals from Precambrian to Quaternary, while other chapters describe the geography, geomorphology, tectonics, geophysical characteristics, and resources of the region. A summary chapter includes geologic maps, structural cross-sections, a geotectonic correlation chart, a gravity map, and a location map for exploration wells in the Arctic Islands and northern Greenland. A wealth of additional information is contained on the nine accompanying plates.

"To recognize the 25th anniversary of the Circum-Arctic Structural Events program, an effort organized by the Bundesanstalt für Geowissenschaften und Rohstoffe, this volume presents results from 18 major field expeditions involving 100+ geoscientists from a spectrum of disciplines. The volume focuses on the Proterozoic to Cenozoic tectonic evolution of the circum-Arctic region with correlations to adjacent orogens"--

Dyke swarms are remnants of large igneous provinces, and are pointers of continental break-up events, as well as indicators for ancient continental reconstructions. These global geodynamic aspects are of crucial significance in tectonics, and with recent developments in high-precision age, dating it has become possible to enter these short-lived ma

Accretionary orogens form at convergent plate boundaries and include the supra-subduction zone forearc, magmatic arc and backarc components. They can be broken into retreating and advancing types, based on their kinematic framework and resulting geological character.Accretionary systems have been active throughout Earth history, extending back until at least 3.2 Ga, and provide an important constraint on the initiation of horizontal motion of lithospheric plates on Earth. Accretionary orogens have been responsible for major growth of the continental lithosphere, through the addition of juvenile magmatic products, but are also major sites of consumption and reworking of continental crust through time.The aim of this volume is to provide a better understanding of accretionary processes and their role in the formation and evolution of the continental crust. Fourteen papers deal with general aspects of accretion and metamorphism and discuss examples of accretionary orogens and crustal growth through Earth history, from the Archaean to the Cenozoic.
