Abstract

Bakarno porfirno ležište Bučim situirano je na granici općina Štip i Radoviš, nalazi se u Srpsko-makedonskom masivu blisko kontaktu Vardarske zone. Dio je Alpe-Balkan-Karpati-Dinaridi metalogenetske provincije u centralnom dijelu Lece-Halkidi zoni. Bučim je dio Bučim-Damjan-Borov dol rudne oblasti i raspoređen je na četiri rudna tijela: Čukar, Centralno rudno tijelo, Vršnik, Bunardžik. Nastao je kao posljedica oligocensko-miocenske intruzije u pretkambrijske gnajseve, škriljavce i amfibolite. Bunardžik je rudno tijelo u obliku potkove gdje do orudnjenja dolazi u gnajsu. Primarno se eksploatiraju halkopirit i bornit koji se pojavljuju diseminirano ili venski. Uzorci su analizirani metodama mikroskopije u prolaznoj svjetlosti, difrakcije rendgenskih zraka na prahu (XRPD), skenirajućom elektronskom mikroskopijom (SEM). Određene su kalijska, sericitna, argilitna i propilitna alteracijska zona.

Abstract (english)

Cu-porphyry deposit Buchim is situated on the border of Shtip and Radovish counties in the Serbian-macedonian massif in close contact to Vardar zone. It is a part of Alpian-Balkan-Carpat-Dinarides metallogenic province in the central part of Lece-Halkidi zone. Buchim is a part of Buchim-Damjan-Borov dol ore field and it has four ore bodies: Chukar, Central ore body, Vrshnik and Bunardzhik. Origin of Buchim’s intrusions date to oligocen-miocen in preCambrian gneiss, schists and amphibolites. Bunardzhik is a horseshoe shaped ore body with ore mineralization in gneiss. Primarily exploited minerals are chalcopyrite and bornite that appear disseminatedly and in veinlets. The samples have been analyzed with polarization microscope, X-ray powder diffraction (XRD) and scanning electronic microscope (SEM). The determined alteration zones are potassic, sericitic, argillitic and propyllitic zones.
