Numerous
native and foreign scientists acknowledge phenomenon of the mineral-forming
fluids effervescence. A lot of scientific works concern with molybdenum,
tungsten, gold bearing and polymetallic deposits. Effervescence phenomenon can
be fixed with a help of postmagmatic deposits inclusions indicating on this
process. Least of all data one can find
for deep-seated rocks and minerals. At the same time theoretical elaboration
cited in the paper testify about the great depth about 150–200 km where
diamonds are conceived. Processes of the mineral formation in endogenous

The features of structure and rocks’ composition of tectono-fluidizate
zones in the Middle-Boug region (Hajvoron, Khaschevata and Zavallya areas) have
been considered. Mineralogical, geochemical and metallogenic peculiarities of
these zones have been adduced. Some minerals of fluidizites (spinel,
phlogopite, celadonite, apatite, hamlinite, gaylussite etc.) have been
described. The certain types of fluidizites crusts of weathering (ferruginous and ferruginous-manganous,
ferruginous-potassic, aluminiferous and siliceous) have been allocated.
Mineragenic features of the region have been caused by tectonic and
lithological factors, penetration of fluidizates, metasomatism and weathering.

The
materials about new mineralogical finds, isotopic-geochemical determinations
and research of fluid inclusions in minerals of granitic “zanorysh”
(chamber)-type pegmatites are presented. Ilmenorutile (niobiumrutile) and
kerite (oxykerite) are thoroughly characterised. The data of determinations of
isotopic contents of carbon of carbonates, kerite and CO2 and CH4
of fluid inclusions in quartz and topaz are shown. New types of own fluid
inclusions are founded and described: formed at repelling common growth and
catching of xenogeneous particles; stuck to the solid fazes (inclusions);
enriched in carbonic substance etc. It is stressed that obtaining these data
was possible because of uniqueness of chamber-type pegmatites of Volyn’ which,
despite of long history of their research and existence of series of
generalisation works, stay in the focus of research. The performed
generalisation allowed to draw the conclusions party sufficiently role of

Basic
plutonic massifs are usually described as comagmatic to volcanic (mainly
tholeiitic) series. It is shown that layered gabbronorite (norite) massifs have
different petrochemical trends as compared to tholeiitic series. They can arise
in active tectonic conditions and are often spatially connected with stress
zones. It is proposed to regard such massifs to independent two-pyroxene
series.
