Sarmatian Craton

Sarmatia's northwestern margin has an extensive continental magmatic arc dating back to 2.0–1.95 Ga.[1] The Ukrainian Shield and Voronezh Massif are the exposed areas of the Sarmatian Craton.

It is exposed only in the northwest corner of the Ukrainian Shield and in the Pripyat Trough (west of the Devonian Dniepr–Donets Aulacogen).

The area was strongly deformed at 1.98–1.95 Ga but it can be interpreted as a setting of intense volcanism and sedimentation in a coastal-marine environment in which island arcs reused detritus from Archaean sources.

More recently, however, it has been demonstrated that the Korosten pluton is not made of mantle-derived igneous material but from the lower crust of the Osnitsk-Mikashevichi Belt extruded in the Central Belarus Suture Zone.

[2] The Podolian Domain in southern Sarmantia is made mostly of Archaean-Palaeoproterozoic granulites (up to 3.7 Ga) and divided by major faults into the Vinnitsa and Gayvoron regions.
