Structural geology of hydrothermal ore systems

自然资源对加拿大未来的经济至关重要。拟议的研究将有助于在马尼托巴省的Flin Flon发现新的铜锌矿床，以及在安大略省的Kirkland湖- Larder湖地区发现金矿床。该研究解决了较少研究的岩石变形对矿床成因和随后的改造的影响。断层在矿床成因中起着重要作用，它形成了集中含金属热液的管道。矿床通常沿活动构造边缘形成，随后在过去海洋造山闭合期间发生变形。Flin Flon的铜锌矿床形成于古代马尼克湾洋的一个洋岛，在该洋的闭合和大陆构造板块的碰撞过程中发生变形。这种变形影响了矿床的几何形状和分布。柯克兰湖-拉德湖地区的金矿床是沿目前不活跃的断层布设的，并在随后的断层活动中变形。提出研究的主要目的是了解变形如何控制这些矿床的成因，改变它们的几何形状，并在加拿大的两个重要矿区重新分配矿床。

Natural resources are important for the economic future of Canada.  The proposed research will aid the discovery of new copper-zinc deposits in Flin Flon, Manitoba, and gold deposits in the Kirkland Lake - Larder Lake area, Ontario.  The research addresses the less studied effects of rock deformation on the genesis and subsequent modification of ore deposits.  Faults play an important role in the genesis of ore deposits by creating conduits that focus metal-bearing hydrothermal fluids.  Ore deposits commonly form along active tectonic margins and are subsequently deformed during mountain-building closure of past oceans.  Copper-zinc deposits in Flin Flon formed in an oceanic island in the ancestral Manikewan Ocean and were deformed during closure of that ocean and collision of continental tectonic plates.  This deformation affected both the geometry and distribution of the deposits.  Gold deposits in the Kirkland Lake - Larder Lake area were emplaced along presently inactive faults and were deformed during subsequent reactivation of the faults. The main objective of the proposed research is to understand how deformation controlled the genesis of these ore deposits, changed their geometry, and redistributed the deposits within two of Canada's important mining areas.
