Abstract [en]

The Malmberget deposit has produced morethan 600 Mt of ore and comprises several ore bodies thatexhibit different mineralogical, chemical and structuralfeatures. In the eastern part, the ore bodies occur asmassive lenses of magnetite surrounded by ore breccia,while the western part is characterized by hematitedominated ores. In contrast to most other apatite iron oresin Northern Norrbotten, the Malmberget deposit have beenstrongly affected by deformation, metamorphicrecrystallization and felsic intrusions.Variations in whole rock chemistry of the ores aremainly reflecting primary features with different signaturesfor massive ore and ore breccia, but also indicatingdifferent types of massive ore. Magnetite from ore brecciahave low content of trace elements similar to magnetitefrom IOCG deposits and may have formed byhydrothermal processes while magnetite in massive oreshow chemical characteristics typical for apatite iron ores.The chemistry of magnetite has in various extentsbeen modified due to element redistribution duringmetamorphic recrystallization and oxidation. Mostsignificant is the preferential partition of Ti and to someextent V into porphyroblasts of hematite. The formation ofilmenite and rutile affects the chemistry of magnetite andgives it a lower content of Ti and V and a signatureresembling magnetite from IOCG deposits.
