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

萨德伯里（Sudbury）火成岩复合物（SIC）以其铜矿石矿石而闻名，是一种火成岩复合物，是由约18.5亿年前的撞击事件的部分融化而形成的。尽管萨德伯里（Sudbury）在一个世纪以来一直在积极采矿，但关于综合体内矿石矿床的形成仍然存在的重要问题。其中一个是，在萨德伯里火成岩综合体中发现的偏移堤防中硫化物矿物质的起源，历史和来源是什么？沃尔布里奇矿业公司有限公司目前探索了其中几个堤坝。到目前为止，关于硫化物从主要质量迁移的条件鲜为人知。使用稳定的Fe-Cu-Ni同位素，我们将确定潜在来源，氧化态，水热史和
