Summary, in English

The Ukrainian Shield and Voronezh Crystalline Massif constitute the Sarmatian segment of Baltica. Here, only a few mafic-ultramafic dykes and layered intrusions have been dated, recording early Statherian (ca. 1800–1750 Ma) ages. We have determined new U-Pb baddeleyite ages for the Novogol sill (1789 ± 2 Ma) and the Gremyachye intrusion (1781 ± 7 Ma), which fall within the previously established age range of mafic magmatism in Sarmatia. Overall, mafic magmatism started at ca. 1800 Ma and reached a peak at ca. 1790 Ma. Several intrusions were emplaced between ca. 1785 and 1775 Ma. The next significant peak in magmatic activity took place at ca. 1760 Ma, although a few dykes are dated as late as ca. 1750. Together, these rocks constitute the Prutivka-Novogol large igneous province (LIP), with the main components consisting of tholeiitic dolerite, sub-alkaline olivine gabbro, high-Ti (picrite, camptonite) dykes, and kimberlite. Abundant anorthosite-mangerite-charnockite-granite (AMCG) magmatism also occurred throughout the Ukrainian Shield, coeval with tholeiitic magmatism. Early Statherian mafic magmatism was widespread in many parts of the Nuna/Columbia supercontinent, and magmatic barcoding demonstrates that the Sarmatia, Amazonia, São Francisco, West Africa, and North China cratons record similar events and were therefore probably in close proximity. This suggests that the Prutivka-Novogol LIP was part of a much larger superplume that affected an extensive area within the newly-formed supercontinent.
