LAMPROITE-LIKE ERUPTIVE BRECCIA OF THE SOLOZERSKY PROSPECT (KOLA PENINSULA)

New data on the eruptive breccias obtained as a by-product in the course of boulder prospecting for copper-nickel ores at the Solozersky prospect in the Northeastern Baltic Shield are given. Mineralogicalpetrographic, geochemical investigations giving evidence that the discovered breccia belongs to the mafic lamproites – orendites family, which brings forth the prospecting problem of bedrock bodies of lamproite like rocks in the context of possible diamond content of the area, are performed.
