An area north of the Arctic Circle is composed of a great variety of tectonic crustal domains and overlying sedimentary accumulations ranging from the pre-Neoproterozoic North America, Baltica and Siberia cratons, to Cretaceous and Cenozoic oceanic basins. In addition, there is a series of Neoproterozoic and Phanerozoic fold belts extending onto the Arctic shelves and forming their tectonic basement. This region is among the least studied parts of our planet, and its tectonics and geological history is among the most debated of any region on Earth. Points that remain highly disputed include the following:

• timing and plate kinematics associated with Amerasia Basin formation,
• Alpha-Mendeleev Large Igneous Province: age of magmatism and nature of crust,
• offshore extent of the Scandinavian Caledonides,
• location of the Uralian Fold Belt beneath thick sedimentary cover in the Kara-Yamal region and its relationship with the Late Paleozoic Taimyr Fold Belt,
• relationship between the Siberian Craton, Taimyr and Verkhoyansk fold belts beneath the Laptev Sea Shelf,
• age and boundaries of the DeLong Massif in the northern East Siberian Sea and its relationship with Kotel'nyi Island geology,
• location of the northern limit of Late Mesozoic compressional deformation across the East Siberian Arctic Shelf,
• occurrence of Caledonian/Ellesmerian compressional deformation on Wrangel Island, the New Siberian Islands and the Severnaya Zemlya Archipelago,
• offshore extent of the South Anyui Suture,
• and many others.

We work on compilation of a new Tectonic Map of the Arctic that is designed to portrait first-order tectonic elements associated with Arctic crust, crustal-scale discontinuities and their ages, as well as the characteristics of the lithosphere as a whole using available published geological and geophysical data.
