ABSTRACT

Balan perimeter is one of the most representative mining zones of the Eastern
Carpathians, well known for its copper ores, represented mainly by massive and/or
disseminated pyrite and chalcopyrite concordantly interlayered with low grade Cambrian
metamorphites of the Tulghes Group.

The chemical study of these accumulations highlighted the presence of elements (Cu,
Pb, Zn, Ni, Co, Mn) which, by geochemical characteristics and behaviour, can be
included in the category of heavy metals and which, by build-up and/or migration in the
surface water network and soils, can become pollution factors.

The present study has the objective of investigating the accumulation and migration
patterns of the mentioned elements in soils.
