One of the great achievements of academician Ye. Lazarenko is the establishment of high-performance school of regional and genetic mineralogy. Its development is implemented by his students. Yevhen Lazarenko began regional mineralogical investigations in Lviv; they reached apogee during his work in Kyiv but today unfortunately gradually decline. Despite difficulties, genetic mineralogy continues its development within the plans of the well-known mineralogist. The article specifies the most significant achievements of his students in the sphere of fluid mineralogy – reconstruction of mineral formation conditions using fluid inclusions in minerals. Examples of non-traditional approaches to reconstruction of PT-parameters of mineral formation are resulted. They combine the results of thermo- and barometric researches in fluid inclusions with the data on physical characteristics of minerals, composition of gaseous products of their pyrolysis and behaviour of melts during experimental hardening.
Key words: fluid inclusions, PT-parameters of mineral formation, melt, liquation, pyrolysis, volatile components, genetic mineralogy.

E-mail: mineral@franko.lviv.ua
Crystallochemical features of high-ferrous dioctahedral mica minerals have been studied in detail. It is found out that chemical composition and crystallochemical features of glauconite and celadonite are similar. But celadonite tetrahedrons are fully settled by silicium, or content of trivalent cations in them is less than 0.2 formula units while in glauconite it is higher. Mixed-layered formations like mica–smectites always are present in the structures of described silicates, and their content is usually from 5 to 30 %, sometimes more. There is a gradual transition of smectites (nontronite) through intermediate mixed-layered phases in celadonite and glauconite. These minerals can be interpreted as mineral species. Skolite, presumably, relates to Al-hydromicas (illite). Glauconite and celadonite relate to hydromicas (not to micas), because the content of potassium in them is less than one formula unit. Described silicates are formed mainly from hydrothermal solutions. Formation of glauconite takes place also during halmyrolysis of pyroclastic material (volcanic ash) which supplies in marine sedimentary basins by air way.
Key words: glauconite, skolite, celadonite, crystallochemical formula, mixed-layered phases, hydromica, hydrothermal solutions, mineral-forming conditions.

Brief generalized mineralogical-geochemical characteristics of diamondiferous kimberlite pipes of the Siberian, East-European and African platforms are given. One can usually distinguish in kimberlite diamondiferous platforms of the world (from bottom to top): à) root part – feeder channel in the form of a dyke body; b) volcanic (vertical) channel; c) cone (funnel-shaped reaming), crowned by ring bank in non-eroded apparatus. Each of these parts is composed by rocks possessing particular material and texture-structural specific features. Sufficient regularities in rock alternation create peculiar vertical zoning of primary diamond deposits.
Kimberlite pipes on East-European platform are characterized by many specific features, which differs them from classic kimberlites of the Siberian and African platforms. Among distinctions one can note enrichment of groundmass with saponite connected with enrichment by quartz of hosting the pipes rocks, as well as kimberlites proper. Mineralogical-geochemical composition of African kimberlites may serve as template, since the rock proper got the name after them.

The alkaline metasomatites (fenites) of Eastern Azov region are unique formations with peculiar constant set of minerals and interesting petrologic peculiarities. They have been formed on granitoids and quartzites. In one case the alkaline metasomatites accompany veined carbonatites (Khlibodarivka career), in the other – they associate with calcite and fluorine-calcite veins with parisite and bastnasite (small ore occurrence Petrovo-Hnutovo, near Kaplany and Naberezhne villages on the Kal’mius river). Original mineralogy of the rocks proves their relation to alkaline metasomatites and gives a possibility to compare them with similar rocks of the Ukrainian Shield different regions. The main minerals of alkaline metasomatites are the alkaline varieties of amphiboles (arfvedsonite and riebeckite), pyroxenes (aegirine, aegirine-salite), feldspars (albite-olygoclase) and low alumina micas (like celadonite). Accessory minerals are presented by zircon, parisite, bastnasite, pyrochlore, britholite, monazite, magnetite, rutile and apatite. Fenites and albitites here and there contain TR, Nb, Mo and Zr mineralization.
