Rezumat

The paper presents petrographic, mineralogical, geochemical description of the alkaline ultrapotassic rocks, whose presence in the, south-western part of the territory of the Republic of Moldova for the first time we have established. Chemical composition and geochemical characteristics distinguish three types of rock: ultrabasic, basic and major mesocratic leucocratic. In general, the studied species of petrochemical principles tend to be species of the family "lamproite". Consequently, known till now magmatic rock complexes and eruptive origin are replenished with a new type of rock - "lamproite".
