Crystal structure defects of rock-forming minerals as genetic marks of metamorphic rocks in the Kola Superdeep Borehole section.

The results of the study of ore minerals contained in ferruginous-siliceous rocks in the SG-3 Archaean unit IX and their surface homologues in various blocks of the north-north-eastern framing of the Pechenga structure have been considered. The compositions of ore mineralization of the ferruginous-siliceous rocks in the SG-3 Archaean unit IX and Rovensky block were found to be similar but they differ from that in Liinakhamary and Suormus blocks. The prevailing content of iron sulfides over the ferrotitanium oxides in the studied rocks of the Rovensky block is likely to be related to the primary ore specialization of the replaced rocks. These ferruginous-siliceous rocks and their magnetites are demonstrated to be of metasomatic genesis.
