Summary(Plain Language Summary, not published)
Zircons (small, resistant minerals) are commonly found in sedimentary rocks. They record age information that can be matched or compared to different possible bedrock source regions of different ages. They can also constrain the time at which the sediments forming the sedimentary rock were originally deposited into the basin. Here, the ages of detrital zircons from two sedimentary packages (Pennington Lake and Armit lake) identified in the Tehery region of the Rae craton in Nunavut are determined. The zircon ages are similar to the bedrock zircon ages of the region suggesting that the sediments were sourced locally. The ranges of zircon ages also show some similarities with previously-studied sedimentary packages west of the Tehery region, the Amer and Ketyet groups, suggesting that the packages were part of a common basin system, and also deposited in the Paleoproterozoic (between 2500-1600 Ma).
