Abstract
Based on the petrological and geochemical data, the formation conditions of the ultrabasic-basic rocks of the Rusinovsky complex of the crystalline basement of Belarus are determined. It is shown that the rocks of the Rusinovsky complex are divided into two petrochemical series: magnesian and titanium-ferruginous. The peculiarities of the rare-element rock composition indicate the melting and processing of the original composition of magma, and its crust contamination. According to the formation conditions of the rock, the complex is close to island-arc formations.
