“…Trettin and Parrish, 1987;Embry and Osadetz, 1988;Okulitch,1991;Trettin, 1991;Embry and Beauchamp, 2008;Harrison et al, 2011;Williamson et al, 2011) and potential field (e.g. ; Oakey and Stephenson, 2008;Oakey et al, 2012) ; Argyle and Forsyth, 1994;Forsyth et al, 1998;Funck et al, 2011) have recognised the presence of notable sedimentary sub-basins on the offshore Canadian Arctic Shelf area. However, the detailed distribution and areal extent of these volcanic and intrusive igneous rock bodies emplaced on and within the underlying thick Mesozoic sedimentary successions across the Sverdrup Basin region, as well as the actual dimensions and relative time of development of the offshore marginal sedimentary sub-basins are not well known.…”
