On the background of description of the chaotic complexes, the melange in the Bieszczady area was studied in detail. It has an evidently tectonic character with features pointing to tectonic deformation – in some occurrences westwards it seems to be rather a chaotic complex of a more complicated, perhaps partly flow, genesis. Generally, the melange zones represent open or close geochemical systems. Due to their strata defragmenta-tion degree, they may be concerned as a path for a fluid flow, a site for mineral crystalliza-tion and/or migration zones of hydrocarbons and mineralized waters. In that context the tectonic melange in the Jablonki and Rabe vicinity was studied from the petrological, min-eralogical and geochemical points of view.
Key words: tectonic melanges, fluid migration, Carpathians.

Primary inclusions brines chemical composition halite from Badenian evaporite formations in the Ukrainian part of the Carpathians Foredeep has been studied. Investigated area is situated near Kalush. The results show that the basin brine belonged to the Na-K-Mg-Cl-SO4-type. The seawater was the main source of salt formation, and the ratio of the ions concentration was close to those in the modern seawater saturated with NaCl by slightly decreased content of SO42–. The brine salinity did not rise over the initial stage of halite precipitation. Significant fluctuations in concentration of brines in the vertical profile of salt deposit are not observed. The reason of decreased content of SO42–-ions was the chemical evolution of seawater in the Cenozoic, in part, probably, the inflow of continental water. The bromine content (15–80 ppm) in halite from Grynivka area also indi-cates the marine source of brines and a relatively low grade of their evaporation.
Key words: salt-bearing deposits, halite, fluid inclusions, brines, ultramicrochemical analysis, Badenian, Ukrainian Carpathians Foredeep.

E-mail: mineral@franko.lviv.ua
Lithologic and mineralogical composition of Mn-bearing part of Bystrytska suite (Upper Eocene) from Pokutski Carpathians is described. Bystrytska suite is the part of flysch formation and consists of fine-rhythmic layering of clastic, clay and carbonate rocks. Gritstones, sandstones and aleurolites have been described among clastic rocks. Gritstones refer to fine-grained lithoid greywackes; sandstones and aleurolites have simi-lar composition and refer to glauconite-quartz variety. Cement usually is argillaceous-carbonate with significant content of Mn. Clay rocks are presented by clays and argillite-like clays of red and green-grey colours. These rocks form speckled horizon which refers to the base of cross-section. Clays consist of illite, montmorillonite and chlorite with minor contents of kaolinite. Carbonate rocks of Bystrytska suite present specific rocks which consist of mechanical mixtures of ÑàÑÎ3, MnCO3, MgCO3 and FeCO3 in different ratios. These rocks consist of different carbonate minerals: calcite, rhodochrosite and Ca-rhodochrosite, Mn-calcite and manganocalcite, kutnohorite (?), siderite and oligonite, dolomite, ankerite (rare), syderoplesite, magnesite. These rocks are proposed to call car-bomixes; varieties of them, in which four components are in concentrations more than 20 %, – pokutskites.
Key words: carbonate manganese ores, carbomixes, pokutskites, flysch, Upper Eocene, Bystrytska suite, Pokutski Carpathians.

Mineralogical-petrologic and lithological-stage investigations of the flysch sedimen-tary deposits in the Ukrainian Carpathians give the possibility to outline the zoning of the postdiagenetic transformations for Cretaceous–Palaeogene sequences. Four subzones of the regional transformations have been distinguished: deep (or late) katagenesis (III); beginning of early metagenesis (>III); early metagenesis (²V1) and late metagenesis (²V2). It is found out that there are veins of hydrothermal origin along with metagenetic calcite or calcite-quartz veins (often with hard black bitumens) in the flysch deposits.

Clay mineral assemblage of Miocene marine (Badenian, Tyras suites) evaporites of the East-European Platform western part were investigated. Water insoluble residue of 11 gypsum samples was studied by means of X-ray diffraction, SEM and complex thermic analyses. The clay minerals of gypsum deposits contain smectite, illite, chlorite and mixed-layer chlorite/smectite and illite/smectite. Smectite in studied samples is a mixture of allotigenic dioctahedral Al-Fe and authigenic trioctahedral Mg structural types. Clay minerals are represented mainly by dioctahedral smectite, illite and chlorite which demonstrates relatively low brine concentration in evaporate basin. Presence of authigenic minerals (trioctahedral smectite and illite) and mixed-layer chlorite/smectite and illite/smectite evidences the beginning of transformation processes.

Ukraine Native copper has been discovered in the crust of weathering of ferrous-siliceous and graphitic rocks of Neoarchaean Buz’ka series in Bilokamyanska structure (Middle Buh Region). Grains of copper are presented by the crystals (to 0,6 mm) of pseudo-tetrahedral, octahedral, cubic habit and by foliated grains. Minerals-satellites of copper are presented by pyrrhotine, chalcopyrite, titanomagnetite and graphite; elements-satellites – by Cr, Ni, Co. Anomalies of Cu have been discovered in the amphibole and two-pyroxene crystalline schists.

Crystalline basement and cover of the Ukrainian Shield have been stripped by mining holes within the limits of local isometric gravitation anomaly in Pivnichno-Gruz’ka area of Kirovohrad block. Geological section of basement and cover in one of the most representative mining holes is interpreted from point of fluidizate-explosive rock- and ore-forming theory. The anomaly is caused by bowing of the cover, filled with clastic terri-gene-clay formation, fluidizate-explosive originally. The features of geological structure, lithologic-mineralogical and geochemical characteristics of the rocks testify to the original source of diamonds and presence of rare metal-rare earth mineralization in the explo-sive-sedimentary rocks of Smilyanskyi ore district cover.
