The studies presented in this paper dealing with trace metals in stream sediments and are intended to selecting promising areas in which to prospect for metalliferous ore bodies. Geochemical exploration for ore deposits and metalliferous regions is based on the concept that the products of weathering and erosion of rocks are mainly distributed in local soils, plants and stream sediments.Results of stream sediment geochemical analysis were taken by the Independent Commission for Mines and Minerals (ICMM) and comprise entire territory of Kosovo. Within the surveyed area a total of 3240 samples of stream sediment were collected and analyzed. In this paper are taken in consideration results for the trace metals lead, zinc, copper, nickel, chromium and cobalt.The concept of a geochemical anomaly as a concentration level above some arbitrarily chosen background or "threshold" value for a particular element cannot be applied rigorously to regional variations over a large area encompassing different geologic regions with widely different rock types. Consequently, we adopted the procedure of determining the frequency distribution for each trace metal and of defining anomalies in terms of the statistics.The geochemical results were explored using a range of common statistical techniques including descriptive summary statistics, statistical distribution and correlation analysis for selected trace metals. Statistical analysis and interpretation the geochemical results from stream sediment sampling for trace metals lead (Pb), zinc (Zn), copper (Cu), chromium (Cr), nickel (Ni) and Cobalt (Co) indicates that there are potential areas for increased exploration on these metals. It is recommended to continue the presented investigations by verification activities including mapping, litho-geochemistry, trenching, drilling. © SGEM2014. All Rights Reserved.

Significant economic mineralizations of Kosova territory are hydrothermal deposits of Pb-Zn. These deposits are located mainly in northern and eastern part of Kosovo, the socalled Trepca ore belt, which has a longitudinal stretch about 80 km and consists of a number of mineralized deposits and occurrences. In the geological context, this ore belt is part of the Vardar zone and associated with volcanic and sub volcanic rocks. Most of these deposits are located in the sequences carbonate and other rocks of different compositions, which are characterized by specific physical - chemical anisotropic features. Based on geological data there are several mechanisms leading to the formation of mineralization in host rocks: by filling or replacement, mass transfer (transportation of mineral mass through hydrothermal solutions), convective or diffusion infiltration. Experiments performed in different conditions have led to the conclusion that, the hydrothermal deposit formations are significantly affected by the metasomatic zoning structure, composition and fluid hydrothermal acidity, temperature and other factors. The change of mineral composition is characterized by the presence or absence of certain minerals and the formation of different mineral zonings. In such a zoning mainly dominate are one or two minerals, while the presence of three or more minerals is rare. With the Merdare fault are associated some mineral deposits and occurrences. So far research and data obtained from mining activities of some deposits have provided satisfactory information on the geology, quality, reserves and their economic value. Increasing the level of knowledge and the possibility of expanding the promising sectors for this mineralization requires clarification of structural, formational and controller criteria of forming known to date deposits and use them in terms of finding industrial mineral concentrations, especially in sectors along the deep faults, considered as the most suitable environments for the currently known deposits. Therefore special subject of this paper will be the possibility of finding of other hydrothermal mineralization south and north of the Artana deposit, within the scope of Merdare fault by using different data including and airborne geophysical survey. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

The Upper Cretaceous Flysch series between Suhareka and Bajice is developed in the psamitic and brecciaed facies. The relation between them is tectonic, but south of the area a gradual transition from one to the other facies has been established. Psamitic Flysch facies is characterized by a constant composition and regular graded bedding on the whole area of its distribution. It is represented by three lithogenous types: limy, sandy and conglomeratic. The limy lithogenous types: is characterized by a fairly good carbonate percentage in the whole series. It was formed by the succession of conglomerates, limy and marly sandstones, sandy limestones, limestones, limy-marls, marls, marly-claystones and claystones. These successions are often graded. The depth of certain members range from banked to laminar. The sediments are poor in organic remains. If exist, they occur either in the conglomerates or in the limestones. They belong the foraminifera species (Globotruncana of Campanian-Mastrichtian age has been determined in the limestones near the floor of the series). The sandy type of Flysch: has been preserved in the tectonic trough of Carraleva Mountains. The folding partly covered the areas prevent us to notice the relation with limy and conglomeratic lithogenous type of psamitic facies. It is most probably that the upper parts of the series are built up of the sandy type. It is mainly built up of the finegrained aleuvrolitic, limy-clay sandstones. Those types of sediments are deposited from dense and slow turbidity currents. Conglomeratic type: is less represented in the field of the sheet Rahovec. These sediments are characterized by high carbonate content (40-60%). The basal petrographic members are either conglomerates or conglomerates limestones, limy sandstones and marly. The graded bedding is pronounced by decreasing of the gravel size going towards the top of the bed. Breccia facies of Flysch: is represented by breccias built up of fragments and partly even of blocks of Sericite, sericite-chloritic and biotito shists, marls and metamorphosed sandstones i.e. fragments of Paleozoic rocks. They are mainly cemented by sericitechloritic and more rarely by Carbonaceous and Siliceous basal cement. The stratification of series partly orientation of fragments caused by sliding of mud, occurrence of graded bedding, swimming of blocks into the other material, indicate that the series underwent some redepositions but not so far. In any case, this indicates the proximity of the source area. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

Economical conditions, Kosova after war, geological construction and also the perspectives of mineral exploration in the definite areas of Kosova has influenced that our territory to be of special importance for many researches that have arose interest to many companies whether international and local companies. Structurally, geology of Kosova is divided in two parts represented in East by Vardar area and in West by Sharr-Korab and Drino-Ivanjice area) of the one part and the other part of NNE - SSW direction between Serbian - Macedonian provinces in Kosova and geological province of Albania Dynarides. Area of different Mesozoic fractures that divides Dynarides and Helenides of relative geo-tectonic units in two parts is called Shkoder- Pejë transversal.
