•Mesoproterozoic, Cryogenian and Ediacaran strata identified at the Igarka Uplift.•Age of the Ediacaran strata confirmed by Pb-Pb and C-isotope data from limestones.•Intraplate rifting at >715 Ma correlates to coeval LIP in Laurentia and Siberia.•U-Pb detrital zircon ages evidence for proximal Neoproterozoic source.
