Structural geology of hydrothermal ore systems

自然资源对加拿大的经济未来至关重要。 拟议的研究将有助于在马尼托巴的Flin Flon发现新的铜锌矿床，并在安大略的柯克兰湖-拉尔德湖地区发现金矿。 这项研究解决了岩石变形对矿床成因和随后的改造的影响研究较少。 断层在矿床成因中起着重要作用，它通过形成通道聚集含金属的热液流体。 矿床通常形成沿着活动构造边缘，随后在过去的海洋造山闭合过程中发生变形。 Flin Flon的铜锌矿床形成于古老的Manikewan洋的一个海洋岛屿上，在该洋闭合和大陆构造板块碰撞期间发生变形。 这种变形影响了沉积物的几何形状和分布。 柯克兰湖-拉尔德湖地区的金矿床沿着目前不活跃的断层侵位，并在断层随后的再活化过程中发生变形。拟议研究的主要目标是了解变形如何控制这些矿床的成因，改变其几何形状，并重新分配加拿大两个重要矿区内的矿床。

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.
