  • Abstract: <jats:title>Petrology of Gabbroides and Isotope Signature of Sulfide Mineralization from Fedorov-Pansky Layered Mafic Intrusion, Kola Peninsula, Russia</jats:title> <jats:p>Samples from Fiodoro-Pansky massif were investigated by polarized light microscopy, EDS electron microscopy and isotope ratio mass spectrometry. We have observed four-stage ore mineralization: (1) magmatic Fe-Ti-oxides, (2) sulfide-ferrous oxide, (3) hydrothermal Cu-Ni-sulfide with haycokite, talnakhite and galena admixture, (4) tiosulfates formed from pyrrhotite. A few sulfide samples from generations (2) and (4) were investigated isotopically. The second generation is isotopically homogenous with δ<jats:sup>34</jats:sup>S close to zero, whilst the third generation shows significantly negative δ<jats:sup>34</jats:sup>S values.</jats:p>
