Isotopic tracers for sulfide formation applied to offset dykes of the Sudbury basin, Ontario

萨德伯里火成杂岩(SIC)是18.5亿年前的一次撞击事件导致地壳部分熔融形成的火成岩杂岩，以铜-镍-铂矿而闻名。尽管一个多世纪以来，萨德伯里的采矿一直很活跃，但关于该综合体内矿藏的形成仍存在一些重要问题。一个问题是，萨德伯里火成岩杂岩中发现的偏置岩脉内硫化物矿物的起源、历史和来源是什么？Wallbridge矿业有限公司目前正在勘探其中的几个堤坝。到目前为止，人们对硫化物从主块中迁移的条件知之甚少。利用稳定的Fe-Cu-Ni同位素，我们将确定潜在的来源、氧化状态、热液历史和

The Sudbury Igneous Complex (SIC), known for its Cu-Ni-PGE ores, is an igneous complex formed from a partial melt of the crust as a result of an impact event ~1.85 billion years ago. Although Sudbury has seen active mining for over a century, important questions still remain about the formation of ore deposits within the complex. One being, what is the origin, history, and source of sulfide minerals within offset dikes found at the Sudbury Igneous Complex? Several of these dykes are currently explored by Wallbridge Mining Company Limited. Little is known so far about the conditions for sulfide migration from the main mass. Using stable Fe-Cu-Ni isotopes, we will identify the potential sources, oxidation states, hydrothermal history, and
