Mihalchenko I. Structural position of formation alkaline sodium metasomatites in the Novoukrainka massif

In dissertation results of studing of substancial composition, external and internal structures, geological relations, structural position of metasomatite bodies and beds of formation of alkaline sodium metasomatites of deep fault zones of Novoukrainka massif are expounded. Formation is complemented apobasite facies (parental rocks - diabase of severinka dyke complex). Zonality of the contact of apogranites and apobasites (apodiabases) facies is investigated. The bodies of alkaline sodium metasomatites occupy L -, P -, R -, Т-, R'-, Fd-positions in structural paragenesis of shear zones of the diagonal system of tectonic breaks. Trend of linear bodies of alkaline sodium metasomatites of Novoukrainka massif are inferior to hierarchical law of secondary structural formation of shear zones; equally with faults they are included in directions of regmatic net of disjunctive breaks. Structural position of formation alkaline sodium metasomatites of deep fault of Novoukrainka massif is determined at level: abstract formation - to the zone of activation (lower Proterozoic Korosten-Korsun-Oktyabrsk's reef-building zone of the north-western reaching); local formation - by the zone of deep fault (submeridional ?aniv- Novoukrainka deep fault); the formation bed - structural draft of faults, which is similar to the "Ж"-type; metasomatite body- by fault which occupy certain position in inherited structural paragenesis of fault zone (L-, P-,R-, Т-, R'-, Fd-position). Key words: geological formation of alkaline sodium metasomatites of zone deep fault, metasomatic facies, metasomatic body, structural position, structural paragenesis, tectonomagmatic protoactivation, deep fault, Novoukrainka massif.
