High‐precision ID‐TIMS U‐Pb zircon ages for 12 interstratified tuffs and tonsteins are used to radiometrically calibrate the detailed lithostratigraphic, cyclostratigraphic, biostratigraphic framework of Carboniferous Donets Basin eastern Europe. Chemical abrasion zircons, use internationally calibrated EARTHTIME mixed isotope dilution tracer, improved mass spectrometry guided by error analysis have resulted in an age resolution <0.05%, or ∼100 ka, these volcanics. This precision allows...

Models indicate that atmospheric transport distances for large eolian particles are limited to tens perhaps hundreds of km owing rapid gravitational settling, yet a number studies modern–recent sediment have documented the enigmatic so-called “giant” (generally &gt;63 µm) grains over thousands km. Additionally, stratospheric injection tephra by volcanic eruptions has potential increase distance volcanically sourced aerosols in particular. Here we report first finding eolian-transported...

The base of the Permian System was originally defined (Murchison, 1841) in Ural Mountains Russia to coincide with strata marking initiation evaporite deposition, now recognized as Kungurian Stage.Since that time, has been lowered repeatedly include a succession faunas post-Carboniferous affinities.Problems correlating different biotic provinces Urals standard have served justify establishment plethora regional chronostratigraphic references.Work Subcommission on Stratigraphy (SPS) focused...
