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Carajás（Serra Pelada）和米纳斯吉拉斯（Gongo Soco和Itabira）富含氧化铁的高品位钯金矿化的形成。这些矿床仍然没有矿物学特征和适当的地质分类，我们有机会对独特的、迄今为止无法获得的岩心材料进行取样。微分析和大块岩石地球化学工作，流体包裹体显微测温，放射性测年技术将有助于深入了解这种特殊的金钯矿化风格，这可能与目前世界范围内争论的铁氧化物-铜-Au存款组。
