    • Detrital zircon U-Pb data for Upper Triassic sandstones of the Auld Lang Syne basin, northwest Nevada, USA

    Metadata Updated: October 30, 2025

    This data release includes raw detrital zircon U-Pb data for isolated sandstones in Upper Triassic deposits of the Auld Lang Syne basin of northwest Nevada, USA. Detrital zircon U-Pb data for 11 sandstone samples (3269 zircon U-Pb dates) were acquired via LA-ICP-MS at the University of Arizona LaserChron Center for 11 sandstone samples. Primary insights from the data are twofold: 1) The data provide information about sediment provenance and indicate that sediment of the Auld Lang Syne basin was primarily derived from near the ancestral Ouachita orogen of Texas and Oklahoma. Sediment was transported to the Auld Lang Syne basin by a Late Triassic transcontinental river system, recorded today by the Upper Triassic Chinle and Dockum Groups of the southern continental interior region. 2) The youngest detrital zircon dates in each age distribution provide estimates of maximum depositional age. Maximum depositional ages are consistent with Late Triassic (Norian) deposition in the Auld Lang Syne basin, an age previously constrained by sparse invertebrate fossil data.
