ABSTRACT

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.
