The project aims at a better understanding of the formation of iron-oxide rich, high-grade palladian gold mineralization in Carajás (Serra Pelada), and Minas Gerais (Gongo Soco and Itabira). These deposits still defy mineralogical characterization and proper geological classification, and we have the opportunity to sample unique and hitherto unaccessible drillcore material. Microanalytical and bulk-rock geochemical work, together with fluid inclusion microthermometry, and radiometric dating techniques will assist in gaining insight into this peculiar gold-palladium mineralization style which may be related to the currently worldwide debated Fe oxide-Cu-Au deposit group.

该项目旨在更好地了解卡拉加斯（塞拉佩拉达）和米纳斯吉拉斯州（贡戈索科和伊塔比拉）富含氧化铁的高品位帕拉第奥金矿的形成，这些矿床仍然无法进行矿物学表征和正确的地质分类。我们有机会对独特且迄今为止无法获得的钻芯材料进行采样，并进行微量分析和大块岩石地球化学工作，以及流体包裹体显微测温和放射性测年。技术将有助于深入了解这种特殊的金-钯矿化类型，这种矿化类型可能与目前世界范围内争论的铁氧化物-铜-金矿床群有关。
