Peculiarities of qualitative substance composition of initial kaolins of the Zhezhelivske deposit
Detailed studies of the substance composition of initial kaolins of the Zhezhelivske deposit were conducted. These investigations revealed an absence of mineral forms of titanium and iron. The quality of raw materials in most of parametres is the same as it is at the best deposits of initial kaolins of the world. An economic effectiveness of mining of the Zhezhelivske deposit was shown.

Age of Zelenogaiskaya and Pavlovskaya Greenstone structure (Near-Azov block)
The greenstone rockes of Zelenogaiskaya Greenstone structure are intrudet by leycokratic granites 2480±20 Ma ago. The Pavlovskaya and Zelenogaiskaya Greenstone structure are formed probably in mesoarchean sinchronously with Greenstones belts of Middle-Dnieper block. The metavolcanics DAT formation are correlate with chertomlyk suite of konka series.

Osipenkovsky granodioritic massif as secondary dislocation structure
Osipenkovsky granodioritic massif is situated on the southeastern part of the Western Priazovsky tectonic block. It represents the system hierarchically subordinated secondary lenses. This structure had been forming on due of displaced deformations and compressing strains under the influence of thermodynamic conditions of amphibolithic metamorphic facies.

Rheological types of Ukrainian Shield dislocation tectonics of Middle-Poboug region (base on results of tectonic-facial investigation)
Seven stages of dislocation transformation of Archean granulite-basic complexes were determined basing on the results of tectonic-facial investigation of Middle-Poboug region. Rheological types of dislocation tectonics of Ukrainian Shield corresponding to these stages were separated. It is showed that the most important role for tectonic architecture of this region had played viscous shistosity-gneissous faults which had formed in P-T conditions of amphibolite diaphthoresis (upper katazone) and coditions of active granitization of granulites that was bonded with poboug complex formation.
Mineralogeny of metasomatic formations of the Ukrainian Shield
The presence of wide range of low-, middle- and high temperature metasomatites of the Precambrian rocks of the Ukrainian Shield was confidently proved. Albitites (uranium) and potassic feldspars (berillium) show limited metallogenic specialisation. New findings of ore bearing beresites-listvenites and greisens broaden the prospects on discovering new ore formations.

Comparative peculiarities of metallogeny of Early Precambrian
The metallogenic peculiarities of Early Precambrian of the major shields and cratons of the world (West African, Kaapvaal, Zimbabwean, Ukrainian, Australian, Canadian, and others) are compared. Are suggested, that the main epochs of the gold mineralization are Mezoarchean (3.2-2.9 Ga), Neoarchean (2.7-2.6 Ga), Paleoproterozoic (2.2-1.9 Ga); of the iron ores mineralization - the Paleoproterozoic; and of the uranium mineralization - Neoarchean (3.0-2.7 Ga), and Paleoproterozoic (2.3-1.8 Ga).
To the problem of gemmology terminology
Specific of the independent scientific discipline is reflected in its terminology. Terms and concepts used often in the gemmology are described in the article. These terms and concepts define mostly the object of the research and status of the gemmology among the other branches of the science.

Main problems of the research of landslide processes in Kanev's Pridneprovye
In the article the information about modern display of gravitational processes in Kanev's Pridneprovye are stated. On the basis of field supervision of landslide processes in Kanev's reserve the basic reasons of their occurrence are revealed, the negative influence on an ecological condition of environment is appreciated. The necessity of constant monitoring natural and technogene processes in this region is determined.
Zonal sequences of the Bashkirian stage corals in Eastern Europe
The stratigraphic units that had been recognized by corals (complexes, zones) are of ecosystem nature, which is manifested in strong change of index fossil associations. An analysis of the most studied sections of Bashkirian stage in Eastern Europe as its stratotype area (Western slopes of the Southern Urals) as "standard" section of the Donets basin testify that these regions had passed three main phases in their geological evolution. In stratigraphic charts three sub-stages of Bashkirian stage should be corresponded to the above mentioned phases, respectively.
HYDROGEOLOGY AND ENGENEERING GEOLOGY
Using of potential of soil water for automatization of irrigation system
Regulator device of soil water regime which, in structure of irrigating system, permit to automatize a process of agricultural crops irrigation. This device implements progressive method of optimization of soil water regime. It does not require any energy sources and provides optimal flow rate. Also this device advantageously differs from other well-known devices by it's simple construction and reliability.

The characteristic chemical and mineralogy material of structure hydro-morphological loam of rocks in contours of structures in comparison with containing subairiai less by a cover is given.
Estimation of Consequences of Barrage's Effect from Piles of Base of Uspensky Cathedral of Kyiv-Pechersk Lavra
The results of an estimation of possible consequences of the barrage's effect from piles of the base of restored of Uspensky Cathedral (Kyiv-Pechersk Lavra are made. The available data testify that there are no bases to consider negative consequences of the barrage's effect essential under fulfilment of the design decisions. It is established, that the reduction of stability of the slope near to the Cathedral is possible in the future in case of increasing of the artificial component of the charge of an earth flow.
Submarine discharge of underground water within the cape of Aya
This paper reflects the submarine fresh-water discharge monitoring within the cape of Aya (south-western part of the Mountainous Crimea). It is suggested that hydro-chemical and hydro-optic differences between underground fresh water discharging under the sea level and marine water make it possible to use these methods while finding the spring in the Crimean shelf.
The problem of environment contamination with petroleum products in Ukraine
The environment of Ukraine is significantly exposed to load of petroleum storing, refining and transport. Environment contamination with petroleum products is considered to be a crisis with hard consequences in the nearest future. Groundwater that is the main source of drinking water supply is the most vulnerable. Nowadays, groundwater contamination is revealed in a large number of cities and towns in Ukraine. More than 120 large water-supply well systems are located in either contaminated or "latent" contaminated areas. Different ways of petroleum migration in the subsurface promote contamination spreading complicating predictions and remedial actions at the same time.
