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 (77,000 sq mi)[1] and is approximately 1,000 km (620 mi) long and up to 250 km (160 mi) 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, which differ in mineralogical composition and geochemical specialization.[2]
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.[3]
