Magnesite-bearing fracture zones of the Zlatibor ultrabasic massif (Serbia) as a discrete structural-morphological type of magnesite deposits in ultrabasites

In this paper, a discrete structural-morphological type of magnesite deposits in ultrabasites, i.e., in magnesite-bearing fracture zones, is presented. The most prominent occurrences of such zones in Serbia are in the Zlatibor ultrabasic massif and they are economically very significant because they contain large reserves of high-quality magnesite, as well as of the accompanying sepiolite.
