Detrital zircon geochronology and provenance of the Neoproterozoic to Late Devonian Franklinian Basin, Canadian Arctic Islands

Untitled

“…Both samples clearly accumulated on the cratonal margin of North America, although the Nation River Formation also received detritus from a peri-cratonic source terrane to the north (Gehrels et al, 1999;Beranek et al, 2010;Anfi nson et al, 2011).…”

“…These samples record infl uence from both the North American craton and the Franklinian orogen to the north (Beranek et al, 2010;Anfi nson et al, 2011).…”

“…Lane, 2013, personal commun. ), some Cambrian strata that accumulated along the northern Canadian passive margin (Hadlari et al, 2012), a broad range of circum-Arctic strata (Amato et al, 2009;Miller et al, 2006Miller et al, , 2010, and the Franklinian clastic wedge (Beranek et al, 2010;Anfi nson et al, 2011) (Fig. 11).…”

“…1) . 12), with subordinate older detritus (Anfinson et al 2011;Beranek et al 2013;Hadlari et al 2014). The detrital age spectra from the Franklinian Basin and Peary Land record the detrital signature of autochthonous strata in northern and northeastern Laurentia.…”

“…Normalized probability density plots comparing the Pearya Terrane sample groups with detrital zircon data sets from autochthonous Laurentian strata and the Arctic Alaska-Chukotka Terrane. Age spectra are from Peary Land (Kirkland et al 2009); the Archer Fiord, Rawlings Bay, and Kennedy Channel Formations in the Franklinian Basin shelf environment (Anfinson et al 2011;Hadlari et al 2014); the Grant Land Formation and Nesmith Beds in the Franklinian Basin deep-water environment (Beranek et al 2013;Hadlari et al 2014); Proterozoic to Cambrian sediments of northwest Laurentia (Hadlari et al 2012); Neoproterozoic to Cambrian strata of the North Slope Subterrane (Macdonald et al 2009;Strauss et al 2013); and Cambrian or younger Group 1 metasediments on the Seward Peninsula (Amato et al 2009) in the Arctic Alaska-Chukotka Terrane. All plots used the same criteria employed for the Pearya Terrane data of this study (see text for discussion).…”
