Magnetic susceptibility mapping and rock magnetic characterization of topsoils from southeastern Bulgaria near the Black sea coast was carried out for delineation of the anthropogenic pollution. The presence of strongly magnetic parent material (volcanites, volcanoclastic sediments) and various soil types (Vertisols, Luvisols, Chromic Cambisols, Planosols, Fluvisols) were taken into account by using normalization of the field susceptibilities to the median susceptibility value, calculated separately for each soil ...

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 m...
