Situated scetch of samples localization in Monchegorsk region (after Voytekhovsky and Neradovsky, 2008, changed by authors).Microscopic image of rock samples coming from the Monchegorsk Massif showing peridotites (sample 1, A, B) and quartz breccias (sample 3, C, D). Images obtained with an optical microscope, the polarizing light, crossed pollars (pl – plagioclases, ol – olivine, cpx – clinopyroxene, opx – orthopyroxene, qtz – quartz, suph – sulfide).Microphotographs of samples of massive sulfide mineralization from Monchegorsk (sample 2). The pyrite crystals with pentlandite and ilmen-ites with titanomagnetites (reflected light, py – pyrite, pent – pentlandite, Ti-mt – titan rich magnetite).Microphotograph of massive sulfide from Monchegorsk (sample 2, bornite, pyrrohotite, reflected light, crossed pollars, born – bornite, pyrr –pyrrhotite, mt – magnetite).Plots of the metals content (wt %) in analyzed sulfide from Monchegorsk.
The results of the δ 34S for the Monchegorsk sulfide minerals samples.
