... a similar environment for it. By contrast, the make-up of the Eqe Bay and Isortoq greenstone belts, in particular the predominance of calc-alkaline volcanic rocks, is more consistent with a subduction-related, collisional setting. The Mary River and Prince Albert groups of the Rae Province, thus, appear...

Probability density diagrams and histograms for detrital zircon samples from Rae Group sandstones of the Amundsen Basin. Approximate stratigraphic levels from which samples were collected are shown on accompanying stratigraphic column (derived from Fig. 2) for the Rae Group (lower Shaler Supergroup). Samples from mainland (Brock and Coppermine Inliers) are shown in left column in stratigraphic order with oldest at base; samples from northern Minto Inlier are shown in right column. Age ranges of potential source regions are highlighted with colored bars. U-Pb concordia age (Ludwig, 1998) is plotted on x-axis. Only results with a probability of concordance greater than 1% are shown. Replicates are not included.

Probability density plots (dashed lines) and kernel density estimates (solid lines) of detrital zircon age distributions for different late Mesoproterozoic to early Neoproterozoic strata from the Laurentia, Siberia, and North China Craton (NCC). The age peaks (Ma) are marked. Data source: Rae Group (Gp)—Turner et al. (2016); Rainbird et al. (2017); Tsezotene Formation (Fm) and Katherine Gp—Rainbird et al. (2017); Uy Gp—Rainbird et al. (1998); Khudoley et al. (2015); Diaoyutai Fm—Yang et al. (2012); this study; Qiaotou Fm—this study; Xinxing Fm—Yang et al. (2012); Shouxian Fm—this study. For ages younger than 1500 Ma, the 206Pb/238U age is used, whereas the 207Pb/206Pb age is used for zircon with ages older than 1500 Ma. All data based on analyses with ≤5% discordance. The patterned polygons depict three major age ranges: I—1.00–1.20 Ga; II—1.34–1.50 Ga; III—1.58–1.68 Ga. Probability density plots—Ludwig (2003); kernel density estimates—Vermeesch (2012).

Diagram illustrating the age relationships between the possible source regions and the Rae Group strata sampled for this study (maximum ages based on our detrital zircon data; see Appendix 1 [see text footnote 1]) to highlight the close linkage of ages and gain an approximation of the lag time required to expose protoliths, erode them, and transport derived detritus from source to sink. Time scale for Mesoproterozoic events in eastern North America is from McLelland et al. (2010). Orogenies: R—Rigolet, OT—Ottawan (highlighted in red), S—Shawinigan (highlighted in green), and E—Elzevirian. Symbols: Black dots— anorthosite-mangerite-charnockite-granite (AMCG) magmatism; white dots—mangerite-charnockite-granite (MCGM) magmatism.
