Summary(Plain Language Summary, not published)
This publication presents U-Pb isotopic data to support age interpretations for supracrustal rocks from the White Hills to Amer Lake area, north of Baker Lake in the Kivalliq district of Nunavut. The data are dominantly from detrital zircon grains from Archean and Proterozoic sedimentary rocks. The data can be used to interpret maximum depositional ages as well as the age of the crustal protoliths that contributed sediment to the depositional basins. The data contributes to understanding when and how the rocks in this area formed and how they may correlate to other units in the area in order to develop better geological models.
