This Data Release accompanies the planned publication, "Paleogene sedimentary basin development in southern Nevada, USA." Included here are U-Pb detrital zircon and Ar/Ar feldspar geochronologic data for middle Cenozoic sedimentary and volcanic rocks collected by Jens-Erik Lundstern and Theresa M. Schwartz in several parts of southern Nevada, U.S. The target strata are the lowest Cenozoic sedimentary rocks deposited above the base-Cenozoic unconformity. U-Pb detrital zircon data were obtained at the University of Arizona LaserChron Center in Tucson, Arizona in February 2021, October 2021, and January 2023. 40Ar/39Ar geochronologic data were collected at the U.S. Geological Survey in Denver, Colorado.

The contents of this data release represent the results of the noble gas composition analysis and are presented in support of the planned publication Gao et al., 2023, titled Lead and noble gas isotopic constraints on the origin of Te-bearing adularia-sericite epithermal Au-Ag deposits in a calc-alkaline magmatic arc. Tellurium (Te)-bearing adularia-sericite epithermal Au-Ag deposits are widely distributed in calc-alkaline magmatic arcs and are an important current and future source of precious and critical metals. However, the source of ore-forming fluids in these deposits remain unclear due to the lack of isotopic evidence on Au-, Ag-, and Te-bearing minerals. To advance understanding of the source of Te and precious...
