Abstract
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 isotope analysis. Late Carboniferous to Middle Jurassic strata on the southern
basin margin are inferred as being predominantly reworked from Silurian to Devonian strata within
the adjacent Franklinian Basin succession. Higher-grade metamorphic detritus appeared during
Middle to Late Triassic times and indicates exhumation and erosion of lower (Neoproterozoic to
Cambrian) levels within the Franklinian Basin succession and/or a direct detrital input from the
Canadian-Greenland Shield.
