“…The PDDP is located in the southwestern part of the East European platform and separates the Ukrainian Shield at the south from the Voronezh Crystalline massif in the north. A large volume of alkaline, ultramafic and mafic igneous rocks is known to be associated with the PDDP [20][21][22][23][24][25][26][27][28][29][30][31] and has been related to a mantle plume during the late Frasnian [25]. Kimberlites related to the PDDP are known in the Prypyat horst (see below) and in the junction between the Azov Domain of the Ukrainian Shield and the Donets Basin [26,32].…”

The results of a laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U–Pb dating and a Hf isotope study of zircon crystals separated from small eclogite xenoliths found in Devonian kimberlites within the Prypyat horst, Ukraine, have been reported. The studied area is located in the junction zone between the Sarmatian and Fennoscandian segments of the East European Platform. Four laser ablation sites on two zircon grains yielded Paleoproterozoic U–Pb ages between 1954 ± 24 and 1735 ± 54 Ma. In contrast, three of four Hf sites revealed negative εHf values and Paleoarchean to Mesoarchean model ages, excluding the possibility that the eclogite xenoliths represented segments of a juvenile Paleoproterozoic subducted slab or younger mafic melts crystallized in the subcontinental lithospheric mantle. A single laser ablation Hf spot yielded a positive εHf value (+3) and a Paleoproterozoic model age. Two models for eclogite origin can be proposed. The first foresees the extension of the Archean lower-crustal or lithospheric roots beneath the Sarmatia–Fennoscandia junction zone for over 200 km from the nearest known outcrop of Archean rocks in the Ukrainian Shield. The second model is that the Central Belarus Suture Zone represents a rifted-out fragment of the Kola–Karelian craton that was accreted to Sarmatia before the actual collision of these two segments of Baltica.

On the basis of the mineralogical-petrographic and geochemical study of igneous rocks of intermediate composition of the Pripyat complex of the Late Devonian Pripyat-Dnieper magmatism area, two subphases of the Pripyat magmatism phase have been definished: late Fransian (Chernin or Skolodino-Chernin) with potassium specification and early Famennian (Turov-Drozdov (Yelets)) with potassium-sodium specification. For the first time, the U–Pb age of titanite from trachyandesites of the parametric borehole Pribor was obtained for rocks of Pripyat-Dnieper magmatism area at 364 ± 1 Ma. These data confirm the Famennian age of the Yelets subphase of the Pripyat phase of magmatism and make it possible to determine the duration of the magmatic activity of this structure at least 14 Ma taking into account the isotope dating of the earliest phases of magmatism in the Pripyat-Dnieper-Donetsk Paleorift Structure as 388 ± 12 Ma, 383.3 ± 3.8, 384.7 ± 3.9 and 383.6 ± 4.4 Ma in the Azov Region and 381 ± 2 Ma in the Pripyat-Dnieper magmatism area.
