Major bishofite deposits have been discovered in Poltava area be oil geologists. The data are given concerning conditions of its bedding, estimated resources, branches of national economy and medicine where bishofite and the products of its processing can be used. Arguments are presented in favour of the idea to start the bishofite-based production of magnium oxide and other magnium products and microelements in the Ukraine tp get extreme shortage of this raw material as well as of the dependence on expensive import.

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 conditions are connected with effervescence phenomenon of the mineral-forming fluids as stimulus for its formation.

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 alkalisation and recrystalization processes in gem-holding paragenesises (topaz and beryl) forming and role in this of heterogenization phenomenon, temperature change and mixing abilities of fluids of different origins in mineral-forming medium.

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.
