Geology, hydrothermal alteration, lithogeochemistry, and genesis of Appalachian orogenic Au deposits

与断层有关的(造山)金矿是全球市场的重要黄金来源，一个多世纪以来对加拿大农村许多地区的经济健康至关重要。这些矿床是含金流体沿这些区域断裂运动形成的，金矿的沉积与断裂几何形状的变化和/或与具有特定化学特征的岩石的反应有关。这项研究将集中在纽芬兰拜埃韦尔特半岛和新斯科舍省盖斯伯勒县的造山型金矿。该项目的目标是：1)了解控制金矿化的地质构造和断层的地质背景、性质和几何形状；2)这些地质构造周围岩石的化学成分在矿化定位中的重要性；3)矿化附近岩石与含金流体相互作用而发生的矿物和化学变化的性质。研究结果将对这些类型的金矿如何形成产生影响，并将创造新的信息和工具，引导加拿大和全球的金矿成矿。

Fault-related (orogenic) gold deposits are important sources of gold for the global marketplace and have been critical for the economic health for many parts of rural Canada for over a century. These deposits form from the movement of gold-bearing fluids along these regional faults with gold deposition associated with changes in the geometry of faults and/or reaction with rocks that have specific chemical signatures. This research will focus on orogenic gold deposits in the Baie Verte Peninsula, Newfoundland and in Guysborough County, Nova Scotia. The goals of this project are: 1) to understand the geological setting and the nature and geometry of the geological structures and faults that control the gold mineralization; 2) the importance of the chemistry of the rocks surrounding these geological structures has in the localization of mineralization; 3) and the nature of mineral and chemical changes associated with the rocks near mineralization that have occurred as a result of their interaction with gold-bearing fluids. The results of the research will have implications on how these types of gold deposits form and will create new information and tools for vectoring towards gold mineralization both in Canada and globally.
