Ukrainian Shield

In geology, the Ukrainian Shield or the Ukrainian Crystalline Massif is the southwest shield of the East European craton. It has an area of about 200,000 km2 and is approx. 1000 km long and up to 250 km wide..

It is a pegmatite geologic province which can be divided into the following megastructures: Middle Prydniprovia, Western Pryazovia, Eastern Pryazovia, Ingulski, Rosynsko-Tikychki, Dnistersko-Buzki and Volyn differing in mineralogical composition and geochemical specialization.

The Ukrainian Shield and the Voronezh Massif consist of 3.2-3.8 Ga Archean crust in the southwest and east, and 2.3-2.1 Ga Early Proterozoic orogenic belts.

The Ilyinets crater is located at the boundary of Rosynsko-Tikychki, Dnistersko-Buzki.
