Structural pattern and neotectonic activity

The north-eastern Serbia is one of the most important ore bearing areas in Yugoslavia and Balkan. The Bor and Majdanpek are world-wide known copper ore deposits. Mineralization is con-nected with the Upper Cretaceous magmatism. The main ore controlling factor is fracture pattern. The investigations of structural and morphological characteristics carried out in the wider Majdan-pek area supplied new data on disjunctive structures and indicated an intensive neotectonic activity. A high degree of correspondence between the older fracture pattern and neotectonically active rup-tures has been discovered. Tectonic activity that produced the Upper Cretaceous magmatism was prolonged through the Tertiary and Quaternary. The older ruptures were neotectonically reactivated, changing many times the sense and intensity of vertical movements. The obtained results are a reliable base for selection of perspective ore bearing areas and ra-tional planning of further detailed field structural and metallogenic investigations.
