The approximately 200 km diameter, 1.8 billion year old Sudbury impact structure, Ontario, is the largest and richest mining district in North America (past production plus current inventory, using todays prices, is estimated at $400 billion). This region has been mined since 1883 but despite this, there are still major outstanding questions concerning our understanding of the Sudbury structure and its ore deposits. The proposed research seeks to investigate the original and significance of so-called Offset Dykes and Sudbury Breccia and their association with mineral deposits. The potential discovery of a new Offset Dyke in the northeast of the Sudbury structure will be investigated. The results of the proposed research will address significant gaps in our current knowledge of the origin and emplacement of the Sudbury Breccia and Offset Dykes, which are important ore hosts.

直径约200公里、有18亿年历史的安大略省萨德伯里撞击结构是世界上最大的 北美最富有的矿区(过去的产量加上目前的库存，按今天的价格计算，是 估计为4,000亿美元)。这一地区自1883年以来一直被开采，尽管如此，仍有主要的 关于我们认识的悬而未决的问题 萨德伯里构造及其矿藏。拟议的研究试图调查原始的和 所谓的偏置岩脉和萨德伯里角砾岩的意义及其与矿床的关系。这个 将调查在萨德伯里构造东北部发现新的偏置堤坝的可能性。这个 拟议的研究结果将解决我们目前对原产地和 萨德伯里角砾岩和偏置岩脉的侵位是重要的赋矿场所。
