We studied the fluid inclusions in minerals from the Cu-containing complexes of Lower Vendian trapped formation (Western Volyn' region), and generalized the results from the point of view of academician Yevhen Lazarenko who investigated the processes of magmatic and hydrothermal mineralization in effusive rocks. The analysis of our results made it possible to justify the need for detailed data in this area, in particular to clarify the conditions of copper flood basalt formation due to migration and redistribution and localization of ore material. Further attention should focus on clarifying the fluid regime of mineralization processes: physical and chemical nature, spatio-temporal sequence of display and parametric variability characteristics of fluids of veinlet-impregnated mineralization. This mineralization is the Earth’s lithosphere natural phenomenon – the direct indicator of migration processes and product of healing of migration fractures.

Chamber pegmatites are confined to shallow depths (1,5–3,5 km) of the Earth's crust, which conditional on general features of the mineral-forming fluids evolution in the cavities of their free growth. Due to lower the temperature and discharge of tectonic stress increases the dynamic porosity and permeability of the pegmatite enclosing rocks. Their increase is reduces the tightness of cameras and accompanied by a change of hydrodynamic conditions mineral-forming systems: from a closed, through transitional it becomes open. Thus there is a natural transition from lithostatic fluid pressure through the intermediate to hydrostatic pressure. For long-term of state of the mineral system are typical of growth a large and giant crystals when PT-parameters which are close to lithostatic or slightly below. These conditions can be realized subject to crystal growth in the flow of mineral-water solution (H2O, CO2, F etc.).

Mineralogy of basalts in Luchychi and Yakyshi layers of Lower Vendian Volynian series is determined by the individual features. Different character of magma differentiation has been educed by petrochemical analysis: differentiation of Luchychi magma was expressed poorly, that predefined by the continuous serve of new material from a magmatic chamber; at Yacoushi time there was the magmatic differentiation caused by fractionating of plagioclase and olivine. Mineral composition has been determined by X-ray spectrometry analysis and optical methods, their relations and sequence of mineral crystallization during a magmatic process has been set. Crystallization of Luchychi lava minerals was in such sequence: titanomagnetite → titanomagnetite + augite → titanomagnetite + augite ± pigionite + plagioclase. For the basalt of Yacoushi layers the sequence of minerals crystallization was following: plagioclase → plagioclase + olivine → plagioclase ± olivine + augite + pigionite → plagioclase + titanomagnetite + augite + pigionite → ilmenite. The different type of lava flows cooling has been educed on the basis of different exsolution features in titanomagnetite.

Mineral and chemical composition of allanite ore of Anadol deposit (Azob region) has been investigated. Two morphologic-genetic types of allanite have been distinguished: more early generation (allanite-1) and late generation (allanite-2). Allanite-2 contains lesser amount of REE (15 %) than allanite-1 (24 %). Allanite-2 occurs with cerianite in the lixiviating areas.The important feature of allanite ore composition is high content of manganese (2, 5 %) and absence of radioactive thorium. The crystalline britholite is investigated for the first time. Unit cell parameters of britholite are: a = 0, 9635 nm; с = 0, 7052 nm.
The hydrothermal alteration products of allanite and britholite are bastnaesite and fluorite. Allanite is unstable under surface conditions, its alteration results in destruction of allanite structure and formation of new phases. Cerianite is the product of allanite alteration and is formed during the weathering. Two morphological varieties of cerianite have been distinguished. There are cerianite-1 with relatively high crystallinity and nanocrystalline cerianite-2 with low crystallinity (39–40 %). Cerianite-1 commonly occurs with allanite. Worth’s attention the high content of cerianite (60–70 %) in allanite-2. High content of Mn in allanite ore indicates the deep origin of ore-bearing fluid with F, which is connected with deep-seated alkaline magmatism.

The fluid inclusions in quartz from veined allanite rock of Anadol REE occurrence have been studied by the methods of thermometry, cryometry and pyrolytic gas chromatography. The conclusion is made that the mineral-forming fluids were heterogeneous (saline solution + gas); their temperature decreased gradually from 160–150 to 140–130 °C, and pressure was considerably less than 30 MPa. Quartz formation depth was less than 3 km. While the temperature decreased from 150 to 130 °C the general concentration of salts in solution decreased from 24 to 16 %; chlorine-calcium solution was changed by chlorine-sodium-calcium solution.

Geological and geochemical researches of the metamorphic rocks and the granitoids from Bilotserkivska structure surround (Peri-Azovian megablock of the Ukrainian Shield) have been executed. This complex represents the deep shear of a tectonic zone which limits the structure. They compose a zone of the viscous-plastic current (shear-zone) which was generated at PT-conditions of katazone (2.06 Ga). Geochemical characteristics of zircon from garnet-biotite gneisses are similar to those of Palaeoarchaean (3 560 Ma) tonalite gneisses, which have been preserved in Bilotserkivska structure. The upper age limit of garnet-biotite gneisses formation is 2 065.1 Ma.

Comparative analysis of gaseous component content in volcanic rocks and spherules is made. The problem is of considerable interest in connection with the new data on the deep mantle origin of the spherules. The study confirmed existing ideas to increase the high-reduced fluids with depth. The increasing of the nitrogen content with the depth has been determined; its content is close to the content of the main component – hydrogen. We suggest a significant increasing of nitrogen's role at the deep levels of the Earth. Based on the results of the gas, mineral and chemical composition of the spherules we suggest that their formation is connected with hypogene processes occurring at the boundary of metal and oxide-silicate geospheres.

It has been set that mineralogical-geochemical facies in Cretaceous–Paleogene flysch of the Ukrainian Carpathians are characterized by three main lithological and geochemical types of sedimentation: grey limestone-clayey-terrigenous (type I), non-carbonate or low-carbonate-clayey-terrigenous (type II), and black carbonate-silica-terrigenous-clayey (type III). They differ in content of organic matter, silica and carbonates. The deposits of the first type belong to alkaline-oxidizing (oxidizing-calcitic), the second – to acid and low-alkaline oxidizing (oxidizing with redeposited glauconite), the third – to reducing (siderite, dolomite or ferrodolomite and low-reducing calcitic) and strong by reducing (primary-sulphide or hydrogen sulphide) facies.

Rock-salt of the central part of the Badenian salt basin of Ukrainian Fore-Carpathians (Hrynivka area) has been investigated. Salt deposit profile by thickness of 256 m has been exposed here by the borehole 525, from which 22 samples of rock-salt have been selected. With the purpose of establishment of distribution character and relative amount of calcium sulphate crystals in halite more than 800 plates of halite have been studied microscopically. It has been set that in 9 samples calcium sulphate crystals are present in significant amount, they are located in the primary inclusions and along growth zones of halite crystals. In addition dolomite was determined in the water-insoluble residue of salts (in 13 samples). These results were compared to our previous data on SO42– and Mg2+ relative contents in brines of primary halite inclusions. It was determined that dependence between chemical composition of brines and presence of sedimentation calcium sulphate and dolomite in the samples exists. In particular the reduction of SO42– content in brine inclusions correlates with the presence of sedimentation calcium sulphate in halite. The possible reason for it is the water metamorphization in salt basin. In-depth analysis shows certain dependence of brines composition in salt basin (Hrynivka area) from the local (continental inflow) sources of waters receipt. A scale of influence of continental run-off of marine brines composition in the basin was minimal.

The article deals with the mineralogy of monazite from crystalline rocks of the Ukrainian Shield. It is marked about the difference of monazite from zircon which crystals commonly contain zircon relicts as cores inherited from substratum. This fact can cause distortion of zircon isotopic age. Received age dating of monazite commonly indicates the age of granite formation. It has been found out on the basis of results of U-Pb isotope dating that the oldest monazite (2,9–2,7 Ga) is present in the rocks of Middle Dnieper megablock. Monazite of Paleoproterozoic age (2,08–1,80 Ga) is most widespread and characteristic for granitoids of Zhytomyr, Berdychiv, Kirovohrad and some other complexes of the Ukrainian Shield.

We have found the initial inclusions of CO2 liquid solution that “stick” to needle-shaped sillimanite crystals in quartz of secondary quartzites of Dibrova deposit (Ukrainian Shield). Their density varies from 0,82 to 0,85 g/cm3. These values correspond to the density of pure CO2 at the temperature of inclusions homogenization of 19,8 and 16,5 °C in the liquid phase. Due to the small size of inclusions the triple point temperature of the contents was identified approximately with an error of 0,5 ° C and in total comprised 57,3 °C. Growth conditions of sillimanite in quartz of Dibrova deposit secondary quartzites are greater than or equal to PT-parameters of intersection point of CO2 density isochors 0,82 and 0,87 g/cm3 with a border of sillimanite field in the diagram of the system andalusite–sillimanite–kyanite, which are ≥ 400 °C and ≥ 205 MPa.
Key words: inclusion, PT-parameters of minerogenesis, quartz, secondary quartzite, Ukrainian Shield.

The most known and interesting ornamental stones of Kryvyi Rih basin are bright brown-yellow tiger's eye and grey-blue hawk's eye. The veins of these semiprecious stones have changeable form; they are framed by the dark-grey host rocks, often folded. Mineralized zones have lenticular form; they belong to the seventh slate horizon of the Saksahanska suite. Their position is controlled by one of Saksahanskyi fault branches.
Key words: tiger's eye, hawk's eye, ferruginous-siliceous formation, Kryvyi Rih basin.

Results of microscopic studies of sulphides being formed at contemporary river sediments have been shown. Vertical mineralogical zoning of river sediments has been discovered. Oxides and hydroxides of iron are formed in their roof. Marcasite crystallizes lower oxygen barrier; it has been partly replaced by pyrite at the bottom of profile. Formed on the early stages of river sediment diagenesis sulphides can be one of the sources of marcasite and pyrite accumulation in the sediments of Black and Azov seas.
Key words: markasite, pyrite, iron hydroxides, microspherulites, diagenesis, river sediments, Ukraine.
