From initiation to termination: The evolution of the Ediacaran Volyn large igneous province (SW East European Craton) constrained by comparative geochemistry of proximal tuffs versus lavas and zircon geochronology

•Final stage of Rodinia break-up was evidenced by lava and tuff of Volyn province.•Time of Volynian volcanic activity has been re-assessed by new sampling and dating.•U-Pb ages were obtained on zircon autocrysts from proximal tuffs.•A terminal effusive episode is dated at 546 ± 5 Ma but initial at 570 ± 7 Ma.•Three phases of activity of distinct dynamics and geochemistry were recognized.•In.
