Native Gold of the Porphyry Copper Mineralization in the Borov Dol Deposit (Republic of Macedonia)

摘要

Mineralogical study of gold in disseminated porphyry copper ores is complicated by its fine (often micrometer size) segregations and low contents (0.n g/t). This paper presents the results of investigation of gold in porphyry copper ores of the Borov Dol deposit (Republic of Macedonia) by an ingenious method. Macedonia is located in the Serbian-Macedonian sector of the Eurasian metallogenic belt of the Tethys. The metallogeny of this region is related to the Cenozoic activation and formation of the volcanoplutonic rock complex in the course of scattered spreading [1]. The major porphyry copper deposits of Macedonia belong to the Leche-Chaldikidi metallogenic zone [2], which is sandwiched between the Serbian-Macedonian massif and the Vardar zone.
