Grenvillian and Caledonian evolution of eastern Svalbard – a tale of two orogenies
Abstract Svalbard is located in the north‐west corner of the Barents Sea shelf and the Eurasian Plate, in a key area for interpreting Caledonian and older orogens in the Arctic region. Recent U–Pb dating in the Nordaustlandet Terrane of eastern Svalbard shows this terrane to consist of a Grenville‐a...

In the Neoproterozoic, easternmost Svalbard may have been part of a wider area of Grenville‐age crust, now fragmented and dispersed around the Arctic.
