ABSTRACT
/Full article available only in Bulgarian language/

After exhausting of the vein ores of ore zone No 1, the detecting of metasomatic ore beds
in the eastern part of Eniovche deposit has prolonged the ore`s life. The analysis of the geologicstructural
situation places in the first place lytological and structural factories for localization of
the metasomatic ore bodies. The lytological factor is predetermined by the presence of marbles
and amphybolites. Its role is additionally increased by the scarn processes , creating much better
conditions for metasomatic replacement. The structural factors play main role at forming
metasomatic deposits. The fault creates additional anisotropy of the massif and leads to
fragmentation of the fitting rocks. The faults take, fit and control the ore process. The horizontal
and vertical amplitudes of the moving by ore zone E-11 and especially its intersections with
north-northwestern faults determine favorable for the forming of metasomatic ore bodies
situation in the marbles and amphybolites. The traced in the region of the deposit nappe surface
is an additional favorable element in the structural situation, playing the role of a structural
screen.
