| Реферат: | eng: In the taxitic gabbro-dolerites of the upper contact zone of the Norilsk-1 intrusion, five boron minerals were found: kotoite Mg-3(BO3)(2), suanite Mg2B2O5, warwickite (Mg,Ti,Fe,Cr,Al)(2)O(BO3), ludwigite (Mg)(2)Fe3+O2(BO3), and azoproite (Mg,Fe2+)(2)(Fe3+,Ti,Mg)O-2(BO3). This is the first find of oxyborates in the rocks of the Norilsk ore-bearing intrusions and in the Norilsk province as a whole. Oxyborates occur as inclusions in olivine in the recrystallization zones of taxitic gabbro-dolerites. This indicates that they formed at the late-magmatic or postmagmatic stage as result of the interaction between rocks and boron-bearing fluids associated with an ore-bearing intrusion. Microinclusions of boron minerals could be the cause of elevated concentrations of boron in the rocks. This is a characteristic feature of Norilsk PGE-Cu-Ni-bearing intrusions that can be used as a prospecting criterion.
