A multi-proxy provenance study of late carboniferous to middle Jurassic sandstones in the Eastern Sverdrup basin and its bearing on arctic palaeogeographic reconstructions

A multi-proxy provenance study of Late Carboniferous to Middle Jurassic sandstones from the eastern Sverdrup Basin was undertaken employing optical petrography and heavy mineral analysis, chemical analysis of apatite, garnet and rutile grains, as well as detrital zircon U–Pb geochronology and Hf iso...
