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...
This document includes sandstone provenance data for Upper Cretaceous to Paleocene strata preserved in the Crazy Mountains Basin of western Montana, USA. The dataset includes detrital zircon data for six samples from the Upper Cretaceous Hoppers Formation (1 sample), Upper Cretaceous Billman Creek Formation (1 sample), and Paleocene Fort Union Formation (4 samples). Detrital zircon data were acquired at the University of Arizona LaserChron Center in 2017.

This document provides two data sets that characterize outcrops of fluvial deposits of the Upper Cretaceous-Paleogene Raton and Poison Canyon Formations of the Raton Basin of Colorado-New Mexico, USA. First, the dataset includes stratigraphic sections measured through fluvial deposits of the Raton and Poison Canyon Formations (ten unique .tif files), currently exposed in roadside outcrops. Second, the dataset includes raw paleocurrent data (one .csv file) measured from features within those outcrops. The data support a journal article entitled "Evidence for variable precipitation and discharge from Upper Cretaceous-Paleogene fluvial deposits of the Raton Basin, Colorado-New Mexico, USA", published by the authors...

This document includes two suites of zircon U-Pb ages that help to characterize the magmatic and sedimentary history of the North American Cordillera between ~28 and 50 degrees north. The first dataset is a compilation of published zircon U-Pb ages of igneous rocks associated with the Mesozoic-Cenozoic North American Cordilleran arc. The compilation of igneous zircon data includes 1,492 U-Pb ages from the Peninsular Ranges, Sierra Nevada, Idaho, Boulder, and Coast Mountains batholiths, as well as spatially and temporally associated igneous bodies. The second dataset is a compilation of published detrital zircon U-Pb ages from Jurassic to Paleocene strata preserved in forearc and foreland basins of the North American...

This document includes two suites of zircon U-Pb data that establish a detailed chronostratigraphy for Cenozoic strata exposed on Bat Mountain of the southern Funeral Mountains, California, USA. The first suite of data includes detrital zircon U-Pb age distributions that characterize the maximum depositional age and provenance of five sandstone samples from the Oligocene-Miocene Amargosa Valley Formation (N=4) and the Miocene Bat Mountain Formation (N=1). The second suite of data includes zircon U-Pb data for five ash-fall tuffs that are interbedded with strata of the Amargosa Valley and Bat Mountain Formations. Together, interpreted eruption ages of tuffs and maximum depositional ages of sandstones constrain deposition...
