Evolution of ore-forming fluids in a post-collisional porphyry Cu-Au system: A case study from the Bučim deposit, Republic of North Macedonia
Strmic Palinkas, Sabina; Perkovic, Ivor; Čobić, Andrea; Jurkovic, Iva; Tasev, Goran; Serafimovski, Todor; Spangenberg, Jorge E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-27)The Bučim porphyry Cu-Au deposit is situated in the westernmost part of the Serbo-Macedonian Massif, Republic of North Macedonia. The deposit is hosted by Precambrian gneisses with tectonically imbedded rare lenses of Palaeozoic amphibolites. The mineralization is spatially associated with intrusions of andesitic to trachyandesitic magmatic bodies. The geochemical signature of the intrusions and ... -
Safe, accurate, and precise sulfur isotope analyses of arsenides, sulfarsenides, and arsenic and mercury sulfides by conversion to barium sulfate before EA/IRMS
Spangenberg, Jorge E.; Saintilan, Nicolas J.; Strmic Palinkas, Sabina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-23)The stable isotope ratios of sulfur (δ<sup>34</sup>S relative to Vienna Cañon Diablo Troilite) in sulfates and sulfdes determined by elemental analysis and isotope ratio mass spectrometry (EA/IRMS) have been proven to be a remarkable tool for studies of the (bio)geochemical sulfur cycles in modern and ancient environments. However, the use of EA/IRMS to measure δ<sup>34</sup>S in arsenides and ... -
Trace Element and Sulfur Isotope Signatures of Volcanogenic Massive Sulfide (VMS) Mineralization: A Case Study from the Sunnhordland Area in SW Norway
Strmic Palinkas, Sabina; Fjellet, Trond; Stubseid, Håvard Hallås; Liu, Xuan; Spangenberg, Jorge E.; Čobić, Andrea; Pedersen, Rolf B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-07)The Sunnhordland area in SW Norway hosts more than 100 known mineral occurrences, mostly of volcanogenic massive sulfide (VMS) and orogeny Au types. The VMS mineralization is hosted by plutonic, volcanic and sedimentary lithologies of the Lower Ordovician ophiolitic complexes. This study presents new trace element and δ <sup>34</sup>S data from VMS deposits hosted by gabbro and basalt of the ...
