Zircon geochronology of Torok and Nanushuk Formations sandstones at Slope Mountain and a Seabee Formation tephra deposit at Ninuluk Bluff, central North Slope, Alaska

Description

Zircon geochronology of Torok and Nanushuk Formations sandstones at Slope Mountain and a Seabee Formation tephra deposit at Ninuluk Bluff, central North Slope, Alaska, Raw Data File 2024-33, presents LA-ICPMS and CA-ID-TIMS U-Pb data for five DZ samples collected from a well-known exposure at Slope Mountain, which is one of the few localities where the transition between mid-Cretaceous Torok and Nanushuk Formations is preserved in outcrop. We also report new U-Pb tephra zircon data from basal Seabee Formation at Ninuluk Bluff, a key-and similarly rare-site where the transition between Late Cretaceous Nanushuk strata and overlying Seabee crops out. These tandem-dated samples were collected during summer field seasons in 2018 and 2019 as part of DGGS's North Slope and Brooks Range foothills basin analysis program. The new zircon geochronology results from Slope Mountain and Ninuluk Bluff are documented and permanently archived herein. These data and report are available from the DGGS website: http://doi.org/10.14509/31152.
