Fluid inclusion studies were conducted in the vein quartz known as the "Marmarosh diamonds" of the Krosno and Dukla zones of the Ukrainian Carpathians, which are potentially oil- and gas-bearing. The "Marmarosh diamonds" contain different types of fluid inclusions which record the evolution of the quartz formation. The inclusions were studied by means of gas chromatography, microthermometry and fluorescence. The following sequence has been observed: methane inclusions displaying characteristic features due to crystallography, light hydrocarbons, complex inclusions with a variety of bitumens, and gas-liquid inclusions with two different hydrocarbon phases. The regions where the light hydrocarbon inclusions occur seem to be the most promising as regards oil and gas prospects.

The present-day state of affairs concerning wastes management in Ukraine is described, and the ways of solving the problems are shown. In the first place, it is wastes minimization by means of their reduction at formation place and reuse. The development of systems of sorting (in the formation place and also central sorting), recycling and composting is of great importance.

Lot of an oil, gas, coal and other technological (sanitary waste landfills, quarries etc.) objects at near border territories of Ukraine are situated. During tens of last years the activity of those objects was provided not in full accordance to demands of nature conservation and in several cases caused the no controlled ecology parameters decreasing. The complex providing of ecological safety of technological objects for progressive development of near border territories are proposed. The results of researches of water, ground and air pollution by some of Lviv region objects are presented.

Geochemiczna charakterystyka macierzystości utworów jurajskich w ukraińskiej części mezozoicznego podłoża zapadliska przedkarpackiego została wykonana w oparciu o wyniki badań 182 próbek pobranych z profili 12 odwiertów. Najbogatsze w materię organiczną są utwory jury środkowej, gdzie mediana TOC wynosi 0,72% wag. Utwory jury górnej są znacznie uboższe w węgiel organiczny (mediana TOC wynosi 0,11% wag). Utwory jury dolnej są całkowicie płonne (TOC poniżej 0,2% wag.). Potencjał węglowodorowy utworów środkowo- i górnojurajskich jest generalnie niski i zwykle nie przekracza 1 mg HC/g skały. W utworach jury środkowej dominuje gazotwórczy kerogen III typu. W węglanach górnojurajskich obserwuje się lokalnie zwiększony udział ropotwórczego kerogenu II typu. Dojrzałość utworów jury środkowej odpowiada początkowej i środkowej fazie generowania węglowodorów termogenicznych w„oknie ropnym", a górnej jury — przejściu z fazy generowania węglowodorów mikrobialnych do fazy „okna ropnego".

Geochemical source-rock characteristics of the Jurassic strata in the basement of the Ukrainian part of the Carpathian Foreland was based on Rock-Eval results of 182 samples collected from 12 wells. The richest in organic matter are the Middle Jurassic strata, where TOC median equals 0.72 wt%. The Upper Jurassic carbonates are much poorer in organic carbon (TOC median equals 0.11 wt%). The Lower Jurassic strata are totally barren (TOC below 0.2 wt%). The hydrocarbon potential of the Middle and Upper 7urassic strata is generally low and usually do not exceed 1 mg HC/g rock. In the Middle Jurassic strata gas-prone Type III kerogen dominate. In the Upper Jurassic carbonates locally increased share of the oil-prone Type II kerogen is observed. Maturity of the Middle Jurassic strata responds to the initial and middle phase of the "oil window", and the Upper Jurassic rocks — transition between microbial hydrocarbon generation phase and "oil window".
